          Introduction

          DiskDupe Duplicates disks fast!

          Thank you for trying DiskDupe. DiskDupe  is the best program  to
          automate your  disk duplicating  needs. DiskDupe  can  duplicate
          disks amazingly fast and without any fuss. Other programs simply
          don't measure  up  to  DiskDupe in  terms  of  speed,  bad  disk
          detection, ease of use, and depth of features.

          DiskDupe duplicates, formats and compares disks in a fraction of
          the time other systems can. It copies even high-density disks in
          a single drive - without swapping! DiskDupe senses when you  put
          a disk in the drive and goes right  to work. If a disk needs  to
          be formatted, that's taken care of automatically. To perform  at
          maximum speed,  DiskDupe bypasses  DOS and  the BIOS  and  talks
          directly to your floppy controller.

          Requirements (Dos version)

          - IBM PC or compatible computer.

          - DOS 3.1 or later.

          - 450k free RAM.

          - Hard disk or network with 2 MB free.

          Requirements (Windows version)

          - IBM PC or compatible computer that will run Microsoft  Windows
          3.1 in Standard or Enhanced  mode, Windows for Workgroups  3.11,
          or Windows 95' (please see the  Note below regarding Windows  NT
          and system performance in general running under Windows).

          - An  installed  copy  of Microsoft  Windows  3.1,  Windows  for
          Workgroups 3.11, or Windows 95'.

          - A hard disk or network with 2 MB free.

          - 4 MB RAM.

          Note: The Windows version, just  like the Dos version,  requires
          direct access to your computer's hardware. This means that  both
          the Windows and Dos versions will  not run under the Windows  NT
          operating system.  Also, the  performance of  both the  Dos  and
          Windows versions may be reduced  when running under Windows  3.1
          and Windows 95'.

          Options Available



          DiskDupe is available in  four options: DiskDupe, DiskDupe  Pro,
          DiskDupe Auto and DiskDupe AutoPro, DiskDupe formats, duplicates
          and verifies disks in a fraction of the time other systems take.

          DiskDupe

          Our basic duplication  software for those  who need to  manually
          duplicate a few disks to a  few hundred, but don't need all  the
          extra  features.  It  reads  the  master  just  once  and   then
          duplicates even  high-density disks  in  only one  pass.  Master
          disks can easily be stored on  the hard drive. There is  support
          for extended disk formats, i.e.  Microsoft's DMF and IBM's  XDF.
          There  is  also   maximum  capacity  formatting,   verification,
          automatic disk  type  and  disk  change  sensing,  multiple  job
          setups, Relay, multi-drive duplicating, data sensing, and 5"  to
          3" conversions.

          DiskDupe Pro

          For those who need the advanced features on top of the  standard
          version. DiskDupe  Pro contains  the same  features as  DiskDupe
          with the addition  of serialization,  drive alignment  checking,
          support for  double  speed  floppy drives,  labels,  disk  sets,
          RamboDisk, custom  "track  definable" disks,  password  security
          system, barcoding, and more.

          DiskDupe Auto

          DiskDupe Auto  has all  the features  of DiskDupe  and also  has
          autoloader support. This  is designed  for those  that want  the
          convenience of an  autoloader but  don't need  all the  features
          yet. Later, DiskDupe Auto can be upgraded to AutoPro to get more
          features.

          DiskDupe AutoPro

          For those wanting to fully automate their duplication,  DiskDupe
          AutoPro contains the same features as DiskDupe Pro with  support
          for all the major  autoloader manufacturer autoloader types.  In
          addition, DiskDupe AutoPro supports: SDS, 2XSDS and 4XSDS floppy
          drives,  produces  log  files  which  track  duplication   runs,
          supports DDNet (a  separate network program  which controls  and
          monitors other stations remotely), allows workstations to submit
          jobs for duplication, supports in-line printers, and more.

          Navigating

          When you first start DiskDupe, you'll see a menu bar across  the
          top, along with  several preconfigured job  dialog boxes, and  a
          tool bar with the Windows version.  The menu bar and job  dialog
          boxes provide the  access to all  of DiskDupe's operations,  and
          the tool bar provides quick access  to the more frequently  used
          features.



          DiskDupe supports both mouse and keyboard use, so you can click
          on each option with the mouse or use the cursor and tab keys  to
          make your selection.

          Using the Keyboard

          If you don't have a mouse,  you can toggle between the menu  and
          job screen by pressing  <F10>.  A  highlighted operation in  the
          menu bar indicates  that the menu  bar is currently  accessible.
          Press <Enter>  to  pull  down  the  highlighted  menu.  Use  the
          Left/Right arrow keys to move from menu to menu and the  Up/Down
          arrow keys to scroll vertically through each menu. Once you have
          selected the desired operation, press <Enter>. You can also  use
          DiskDupe's hot keys to  make your selection.  To access a  menu,
          press the  <Alt> key  with the  colored  letter of  the  desired
          operation. Once the  menu is displayed,  press only the  colored
          letter of the desired operation. For example, to select a  drive
          as your  destination, press  <Alt><J>, <D>,  <D>, highlight  the
          desired drive and then press <Enter> to ok your selection.

          Once DiskDupe is set up, most users find it easier to operate it
          through the job dialog box, since all of the current selections
          are displayed in the  box. To operate  DiskDupe through the  job
          dialog box without a mouse, press  <F10> to get out of the  menu
          bar. Use the <Tab> and <Shift><Tab> keys to scroll through  each
          function and press  <Enter> to  make your  selection. Press  the
          space bar to select check boxes  and the <Esc> key to cancel  or
          go back one step. You can  also use DiskDupe's hot keys to  make
          your selection  --  <Alt><C> to  select  the number  of  copies,
          <Alt><O> to  select  the  desired  operation  and  <Alt><G>,  or
          <Enter> to go.

          Using the Mouse

          Navigating the  menus is  easy if  you have  a mouse  installed.
          Simply by pointing on a menu item or selection and clicking  the
          mouse button you get the same  kind of control that you can  get
          from the keyboard.

          You can change job items, in the job dialog box in the middle of
          the screen, directly without having to navigate through the  Job
          menu. For example, to  change the Source to  Relay click on  the
          field next to the word "Source" in the job dialog. The same menu
          selection that is available from Job|Source will be displayed.

          Opening Files

          When opening a file from the File menu, you can type the name of
          the  file  and  DiskDupe  will  add  the  appropriate  extension
          automatically. If you want to open  a file that doesn't have  an
          extension, type a "." after the  filename. You can also enter  a
          new directory  and press  <Enter> to  see the  files in  another
          directory or point  to a file  or directory in  the list box  to



          open it. DiskDupe will remember the last directory you used  the
          next time you need to open a file.

          Getting Help

          If you're ever in need of assistance, DiskDupe has an  extensive
          on-line Help  file to  answer any  of  your questions.  You  can
          access the Help  file through the  menu bar or  by pressing  the
          <F1> key. Pressing  the <F1> key  displays help information  for
          the current dialog you are in. If the current dialog is an error
          message, pressing the  <F1> key displays  an explanation of  the
          error as well as some possible remedies for preventing the error
          from reoccurring.

          Job basics

          If you  have  jobs that  require  custom specifications,  it  is
          worthwhile to  set up  separate  jobs. A  job  stores all  of  a
          specific job's setup  information. This information only affects
          the current job and keeps you from having to select your source,
          destination and various duplication parameters every time you want to
          copy a different disk.                                Once a job is set  up, all you need  to do
          to duplicate the disks specified in that job is to open the  job
          file and press Go.

          To create a job:

          1.   Select New from the File menu.

          2.   Select Job and type the name of the job you want to create.

          3.   Choose your  Source,  Destination and  any  other  specific
          parameters required for this job.

          4.   For other  options, go  into the  Job menu  and select  Job
          Options to select additional parameters for the specified job.

          To use a job for duplication:

          1.   Select Open from the File menu.

          2.   Select Job, choose the job file you want to use, and  press
          Ok.

          3.   Since the  parameters have  already been  preset, press  Go
          when you are ready to begin your job.

          Note: Jobs can also be opened by pressing <F3>.

          To delete a job:

          1.   Select Open from the File menu.



          2.   Select Job,  choose the  job file  you want  to delete  and
          press Delete.

          Using the Preconfigured Jobs

          DiskDupe comes preconfigured with several jobs. The job you will
          probably be using most  often is Main. Main,  and all the  other
          jobs you create, are based on  the settings of the Default  job.
          If you change  the Default job  parameters, then  every job  you
          create afterwards is based on the new Default job settings.

          Two of the preconfigured  jobs you might  find useful are  Quick
          Format and Create  Image. Not only  because you  might be  using
          them all the time,  but because they might  give you some  ideas
          about creating your own jobs.

          Quick Format can be used to delete all the files and directories
          of an already formatted disk. It  does this by first asking  you
          what drive you want to format to (this is an example of the  Ask
          Each Time feature that is discussed in another section), then it
          only formats  the  disk if  necessary  and verifies  only  after
          formatting. If the disk is already formatted it just writes over
          the FAT and Directory Listing on the first cylinder of the disk,
          effectively erasing or deleting all the files off the disk.

          Create Image is an alternative method to using File|New|Image to
          create an image. What  it does is ask  you for the Source  drive
          and the name of the new image  without having to set the job  up
          yourself.

          Copying Disks

          DiskDupe has two basic  operations - duplicating and comparing.
          You can also format disks, which is a variation of duplicating.

          Duplicate makes a copy of a disk and Compare checks that two  or
          more disks are identical. The Copies setting controls the number
          of copies that are made. Enter 0 to copy continuously.

          Whether you are duplicating or comparing, DiskDupe always  works
          from the Source to the Destination.  It copies from the  source,
          sometimes called   the  master disk,    to the  destination,  or
          target disk.

          Although the simplest way  to use DiskDupe is  to copy from  one
          drive to another drive, other ways are useful for certain tasks.
          Two other  common ways  of working  with disks  in DiskDupe  are
          Relay and Cascade. There are  also variations, such as  creating
          an image of a disk on your hard disk and making copies from that
          file.

          For quality and speed, a good, all-purpose setting for Format is
          If Necessary and  for Verify  is Always.  For convenience,  Disk



          should always be  set to  Auto unless  you are  working with  an
          uncommon format.

          Regardless of the options chosen,  DiskDupe makes an exact  copy
          of a disk,  including hidden and  system files,  subdirectories,
          and volume labels. However,  DiskDupe cannot make duplicates  of
          copy protected disks.

          Comparing while Duplicating

          The Compare  function  performs  a  byte-by-byte  comparison  of
          copied disks to  the original disk  or an image  file to  ensure
          that they are  exactly the same.  Disks can  be compared  either
          while they are  copied, by setting  Verify to  Always under  the
          Format/Verify option, or in a  separate step, using the  Compare
          option under Go.

          If there  are any  errors  on the  disk,  DiskDupe will  show  a
          message on the screen indicating that the disk is bad.

          Stand-alone Compare

          The Compare option works nearly  the same as Duplicate,  whether
          you're comparing from  a disk, an  image file,  or using  Relay.
          Follow the same instructions, but select Compare instead.

          When comparing  a master  disk to  a copy,  be sure  to put  the
          master disk in first. Otherwise  DiskDupe might report an  error
          in the unused portion of the copied disk.

          One minor difference  between Compare and  Duplicate is that  if
          you specify  10  copies, DiskDupe  will  compare just  10  disks
          whether they are good or bad. With Compare, for example, if  the
          last disk  is  bad  DiskDupe will  not  ask  for  another  disk.
          Duplicate, on the other hand, will make 10 good disks. Thus,  if
          DiskDupe found three bad disks while duplicating, you would have
          ended up putting in thirteen copies to get the 10 good disks.

          Comparing or Duplicating with Detect Data Area

          When it  is necessary  to copy  or compare  the contents  of  an
          entire disk, which includes the areas outside of the normal data
          area on the  disk or image,  the Detect Data  Area option  under
          Job|Option should be selected.

          Normally, when  duplicating or  comparing  an original  disk  or
          image to a copy, DiskDupe will compare only the data portion  of
          the original to the copy. If the unused portion of the copy  has
          some deleted files  on it for  example, and if  the data on  the
          original disk does not extend completely over the deleted  files
          on the copy, the deleted files will still be present even though
          a complete disk to disk copy was made.



          If the disks are compared with  the copy now being the  original
          and the  original being  the copy,  DiskDupe will  report a  301
          Compare Error because  the deleted file  data is still  present.
          Selecting Detect Data Area solves these kinds of problems.

          Drive to Drive Copying

          The most straightforward way  to duplicate is  to copy from  one
          drive to another. This is useful for making a specific number of
          copies of disks of different types and sizes.

          To copy from drive to drive:

          1.   Select Source from  the job  dialog box.  Select the  drive
          (usually A: or B:) that you will be reading from.

          2.   Select Destination  from the  job  dialog box.  Select  the
          drive that you will be copying to.

          3.   Select  the  appropriate  settings  for  Disk,  Format  and
          Verify. For good, all-around settings, set Disk to Auto,  Format
          to If Necessary and Verify to Always.

          4.   Press Go when you are ready to begin duplicating.

          DiskDupe will prompt you  to put the master  disk in the  source
          drive and the drive light will turn on. As soon as you close the
          drive door,  DiskDupe  will start  reading  the disk  into  your
          computer's RAM,  or  memory, using  your  hard disk  as  virtual
          memory if necessary. This allows DiskDupe to make as many copies
          as you want without having to reread the master disk.

          When you use DiskDupe with your  autoloader, all you need to  do
          is insert a stack of disks in the input hopper and DiskDupe will
          control the duplication.

          Copying with Relay

          Relay is an  extremely efficient  method of  backing up  program
          disks or making copies of a shareware library. To use it,  first
          make sure all your master disks have write-protect tabs on them.
          Relay senses the write-protect tabs and automatically reads  and
          copies the master  disks to  all the  non write-protected  disks
          after each  master  disk. This  allows  you to  make  copies  of
          different master disks of one type without using the keyboard.

          To copy disks using Relay:

          1.   Set Source to Relay and Destination  to the drive you  will
          be copying to.

          2.   Before duplicating, make  sure all your  master disks  have
          write-protect tabs on  them and press  Go. DiskDupe will  prompt



          you to insert  the first write-protected  master disk. After  it
          reads the master, insert  the disks you  want the master  copied
          to. When you want to start copying from the next write-protected
          master, just insert it into the  drive. DiskDupe will sense  the
          write-protect tab  and  read  the  new  master  disk  without  a
          keystroke. After it reads the new  master, insert the disks  you
          want the new master copied to, and so on.

          3.   When you are finished, press <Esc>.

          When you use your autoloader, the process is much simpler. Start
          by putting the first write-protected  master on the desk.  Count
          out the number  of copies you  want made from  that master,  and
          stack that many disks  on top of the  master. Do this until  you
          have a stack with all the masters and empty disks that you  want
          copied. Put the stack  into the input  hopper and DiskDupe  will
          proceed to copy them using Relay.

          Caution: If your master disks do not have write-protect tabs  on
          them, they will be overwritten.

          Copying with Cascade

          If you have more than one floppy drive of the same type and  are
          making  multiple  copies,  you  can  use  Cascade  to  get  more
          efficiency out of  your drives.  With Cascade,  once the  master
          disk is read, DiskDupe cycles through  and makes copies in  each
          drive, beginning with the drive from  which the master disk  was
          read. You can cascade up to 20 drives.

          Cascade won't write  to two  drives simultaneously,  which is  a
          limitation of the IBM PC hardware. Using Cascade, however, saves
          the time it takes to change the disks and saves you from  having
          to change the disks often.

          To copy disks using Cascade:

          1.   Select Source and choose the image  file or drive that  you
          will be reading from.

          2.   Select Destination, choose Cascade, and enter the drives in
          the order you wish DiskDupe to cycle through them. For  example,
          if you want to copy to drive A and B, type AB:.

          3.   Select Duplicate and press <Go>.

          If you designate your Source as a drive, DiskDupe will read  the
          first disk, wait for you to remove the disk and insert new  ones
          in all the drives. DiskDupe will  sense the disk change, make  a
          copy in the first  drive, and then switch  to the next drive  to
          make a copy. It will make copies until it reaches the end of the
          cycle, where it  waits for you  to change the  disks in all  the
          drives. DiskDupe will sense  when you insert a  new disk in  the



          first drive  and  resume copying  immediately.  If the  disk  is
          changed in the first drive, before  DiskDupe reaches the end  of
          the cycle, you must  press <Enter> to resume  copying. If a  bad
          disk is encountered, you will have to remove it and insert a new
          disk in that same drive before DiskDupe resumes duplicating.

          Relay and Cascade

          You can also combine  Cascade with Relay. In  such a setup,  the
          first write-protected master disk is  read from the first  drive
          in the cycle  and will be  copied to  every non  write-protected
          disk inserted in the following drives. It will continue, through
          the cycle, to  make copies of  the first disk  until the  second
          write-protected master disk is read, and so on.

          Images

          If  there  are  disks  that  you  copy  frequently,  it  may  be
          worthwhile to store an image of these master disks on your  hard
          disk. Not only is reading an image file from your hard disk much
          faster than  reading a  floppy disk,  using the  image  prevents
          undue wear and tear on the disk. The drawback to image files  is
          the space they take  up on your hard  disk. Image files  contain
          the data on the disk plus a  header which for a half full  1.4MB
          disk amounts to about 730K.

          DiskDupe images are always forwards-compatible which means  that
          images made with older versions of  the software will work  fine
          with newer versions.  Also, images made  with both DiskDupe  for
          Dos and DiskDupe for Windows are compatible with each other  and
          can be interchanged.

          To Create an Image File:

          1.   Under the File menu,  select New and  then Image. Type  the
          name of the image  file you want to  create, such as  DISK1.DDI.
          When you have finished, press Open.

          2.   Select the drive that the master disk will be read from (A:
          or B)  and press  Ok. DiskDupe  will prompt  you to  insert  the
          master disk into the  drive. The image file  will be created  in
          the current subdirectory.

          You can also create image files the same way that you copy  from
          disk to disk, except that you would choose Drive as your  Source
          and Image as your Destination. When creating the image file, the
          Copies setting has no effect.

          To copy from image to disk:

          1.   Select Source,  Image. Select  the image  file, then  press
          Open. The copy  type will be  automatically set to  that of  the
          image file.



          2.   Select Destination, and the drive you want to copy to.

          3.   Set the number of Copies,  using 0 for continuous  copying,
          and select Duplicate. When  you  are  ready to duplicate,  press
          Go.

          To compare a disk with a  previously created image file,  select
          Compare from the Go dialog box and press Go. DiskDupe will do  a
          byte-by-byte comparison of the copies.

          Using Images on a Network

          If you are  running DiskDupe on  a network, image  files are  an
          easy way to duplicate disks at a number of workstations. Instead
          of distributing master disks  to each workstation, create  image
          files on the network. More than  one user can then run  DiskDupe
          to make copies as needed. And, it is a simple process to  update
          an image file on the network if its data changes.

          Image files  stored on  the network  can  be shared  by  several
          workstations. For example, one  workstation can duplicate  disks
          from the  image file  while another  compares them  to the  same
          image.

          Formatting Disks

          With DiskDupe,  you can  either format  a disk  as it  is  being
          duplicated or separately.  When you copy  disks with  Duplicate,
          DiskDupe will detect whether a disk  has been formatted and,  if
          necessary, format it  while copying.  Use Format  as a  separate
          feature whenever you want to preformat  disks ahead of time  for
          later use  with DiskDupe  such as  making  master disks  or  for
          general Dos use.

          To format a disk:

          1.   Set Source to Format.

          2.   Set Destination to  the drive you  will use  to format  the
          disk and press Ok. This can be  one drive or a number of  drives
          using Cascade.

          3.   Go  to  Format  and  Verify  and  select  the   appropriate
          settings.

          4.   Set the number  of Copies, or  set it to  0 for  continuous
          copying, and select  Duplicate. When  you are  ready to  format,
          press Go.

          Note: If you set  Disk to Auto, DiskDupe  will ask what type  of
          disk you are formatting, otherwise, you can set Disk to the disk
          type.



          Quick Format

          To do a quick format, select the Quick Format job or set  Format
          to Only If Necessary and Verify to Only After Format and  follow
          the above instructions for formatting a disk.

          Reformatting a  disk that  has been  previously formatted  takes
          only about 2 seconds  per disk. This  effectively wipes out  the
          data on a disk by writing  over the disk's FAT (File  Allocation
          Table) and  directory  table.  DiskDupe will  format  the  first
          couple of tracks,  where the file  and directory information  is
          located, realize that the disk doesn't need to be formatted, and
          prompt you for another disk. If you  run a DIR or CHKDSK on  the
          disk, you will see that the disk is indeed empty.

          If you also want to recheck the  disk to make sure there are  no
          damaged areas, set the Verify option to Always. This is  quicker
          than a  full  reformat,  but will  check  the  entire  disk  for
          defects.

          Note: Although the disk appears blank, some of the data is still
          physically on the disk. The only time this might pose a  problem
          is if the disk contains sensitive  information that you want  to
          be sure to  wipe off completely.  If so, use  the full  reformat
          option.

          Full Reformat

          To do a full reformat, select the Full Format job or set  Format
          to Always and follow the instructions  for formatting a disk  as
          described earlier.

          Perform a full  reformat if you  plan to use  an old  disk as  a
          master disk or want to completely erase all the data on it.

          Format Compatibility

          When DiskDupe formats disks, it places  a Dos 3.3 boot track  on
          the disk. This is  compatible with all versions  of Dos. If  you
          want to format a disk with the boot track of another version  of
          Dos, or make a bootable disk or make formatted Unix, Midi or Mac
          high density disks, follow these instructions.

          1.   Format a  disk using  the normal  format command  for  that
          system. With Dos this is FORMAT /U.

          2.   Use DiskDupe to make a copy  of this disk. If you want  you
          can also create an image file of  this disk and use that as  the
          Source.

          If you are using a master disk formatted with Dos 4.0 or higher,
          DiskDupe will copy the serial number of the master disk  without
          changing it.



          Extended Disk Formats

          DiskDupe 5.1 has been enhanced to   support Microsoft's 1.68  MB
          DMF format, as  well as IBM's  1.84 MB OS/2  format. The  copies
          made will contain  the same data  as the original,  but will  be
          arranged slightly differently.  This will in  no way affect  the
          readability of the disk.

          Additional Extended Disk Formats

          Besides support for the above mentioned formats, we've created a
          few of our own:

          400 KB Double Density 5.25" disks

          1.36 MB High Density 5.25" disks

          800 KB Double Density 3.5" disks

          1.68 MB High Density 3.5" disks

          1.84 MB High Density 3.5" disks

          These formats can be used by developers to distribute their  own
          software.  They allow the diskette to hold more data than with a
          standard format by  increasing the  number of  data sectors  per
          track of the disk, and reducing the gap size between each sector
          on the  disk  (the ``sector gap ''                                           ).   When  the sector  gap  is
          reduced it  is  harder for  the  controller to  read  sequential
          sectors,  so  the  sectors  are  interleaved  on  the  disk   by
          separating sequential sectors by one  sector.  For example  with
          the 800K format  each track has  10 sectors  with the  following
          order: 1,6,2,7,3,8,4,9,5,10.  When  a disk is read  on a PC  the
          floppy controller in the  PC reads the sectors  in order, so  it
          has plenty of  time between sectors  to get ready  for the  next
          sector in the sequence, even  though adjacent sectors are  close
          together.

          Extended disk  formats take  longer to  copy than  normal  disks
          because of  the  sector  interleave.    Since  the  sectors  are
          interleaved the controller needs for the  disk to spin twice  as
          many revolutions as a normal disk to read and write the  sectors
          in order.  Allegro controllers speed  up the process by  writing
          the sectors in their interleaved order, although it has no speed
          advantage when reading the disks.

          Using or Distributing Extended Disks

          Most drives will have problems reading disks from Dos that  have
          more data sectors  than normal.    While users  will be able  to
          produce a directory of the disk,  they will be unable to  access
          most files.    To eliminate  this  problem DiskDupe  comes  with



          FixFlop, a small memory resident program which patches Dos to be
          able to access disks with these formats.

          If you're distributing  your product on  a 1.68 MB  disk,   make
          your first disk a  regular 1.44MB and  make the remaining  disks
          1.68 MB. This will allow the  installation program to load  from
          the first disk and run FixFlop so that the rest of the disks can
          be accessed.

          If you want all your product disks  to be 1.68 MB, you must  run
          FixFlop first  and then  run the  install program.  This can  be
          accomplished by making an install  batch file that runs  FixFlop
          first, and then installs the rest  of the files. If FixFlop  and
          the install batch  file are  small enough  to fit  on the  first
          cylinder of the disk, then Dos  will be able to run these  files
          without having to run FixFlop first.

          FixFlop does  not need  to be  loaded if  the product  is  being
          installed from Windows 95.

          Ask Each Time

          The Ask Each  Time option  is ideal  for duplication  activities
          that involve the constant selection and re-selection of  images,
          sets, drives, RamboDisks, cascaded  drives, serial files,  label
          files and DiskDupe protection files during one setting.

          When active,  and before  you begin  a job,  the Ask  Each  Time
          selection you've chosen will bring up a dialog that will ask you
          to select the appropriate new  item. This minimizes the  chances
          of selecting an item  incorrectly, such as selecting the source
          as a  drive instead  of  an image,  and  reduces the  number  of
          keystrokes required  to  make a  new  selection, since  you  are
          automatically put back into  the appropriate dialog when  making
          your next selection.

          A good time to  use Ask Each Time  is when duplicating  multiple
          images, since you minimize the  chances of duplicating from  the
          wrong image, and you won't have to navigate as many menus  after
          each image is copied.

          Another good  time to  use Ask  Each Time  is when  you want  to
          create a  job  that  automates some  routine  process,  such  as
          formatting some  disks.  To create  a  handy format  job,  first
          create a  new job,  then set  the job's  Source to  Format,  the
          Destination to Drive, select the Ask  Each Time option from  the
          Drive dialog, and set Disk to Auto. Now, when you want to format
          a disk, open the new job and press Go.  DiskDupe will prompt you
          for the drive you want  to format to, and  then ask you for  the
          format capacity.

          The  Ask  Each  Time  option  can  be  found  under  Job|Source,
          Job|Destination, Job|Serial, Job|Label and Job|Protect.



          Track Range

          When copying disks, Track Range controls  which parts of a  disk
          are formatted, written and verified. This saves time if you  are
          duplicating disks  that  are  not full.  Track  Range  has  four
          options which can be  set by selecting Range  in the job  dialog
          box.

          With Track  Range  set  to  All,  DiskDupe  formats,  writes  or
          verifies the entire disk, whether or not it contains data.

          With Track  Range  set  to Data,  DiskDupe  formats,  writes  or
          verifies only the  part of the  disk with data.  On a  partially
          full disk used to  install software onto a  hard disk, the  Data
          setting can save  the time DiskDupe  takes to  format, write  or
          verify the  unused  space. However,  anyone  who tries  to  copy
          additional files to this disk or  make a copy with Dos  DiskCopy
          will get an error  because the empty space  on the disk has  not
          been formatted. This can serve as a type of copy protection.  In
          addition, since most disk defects occur in the last tracks,  you
          will get more ``                         good'' disks.

          The Serial setting  in DiskDupe Pro  and AutoPro  is useful  for
          applying serialization in a second pass. DiskDupe will only copy
          or compare tracks with serial numbers.

          The None  setting in  DiskDupe Pro  and  AutoPro is  useful  for
          applying copy protection or printing labels without copying  the
          disk.

          Disk Conversion

          DiskDupe allows you to convert certain  types of disks to  disks
          of another physical size, such as a from a 5.25", 1.2MB disk  to
          a 3.5",  1.4MB. You  can, for  example, copy  a program's  5.25"
          program disks to 3.5" disks for  installation on a laptop  which
          only has a 3.5" drive.

          Converting disks is just a special application of the  Duplicate
          command. The table below indicates which disks, drives, and menu
          settings to use for a conversion. The conversions listed are the
          only ones presently supported.

          DiskDupe transfers  the  information  track-by-track,  including
          hidden and  system  files, volume  labels,  and  subdirectories.
          During a conversion, the destination  disk will be formatted  to
          the same capacity as the source disk. So if you are copying from
          a 5.25", 360K disk to a 3.5", 720K disk, the 3.5" disk will have
          a capacity of 360K.

          Track-by-track disk conversion won't copy from a higher  density
          disk to a lower  density disk, even if  the higher density  disk
          has just a few files on it. So you can't use disk conversions to



          convert a 1.4MB disk to a 1.2MB disk. In this case, it's  better
          to use the Dos Copy command to transfer the files.

          720K to 5.25" Conversion

          When converting a 3.5" 720K disk to a 5.25" size disk, you  will
          need to copy to either a 360K disk or a 1.2MB disk, depending on
          your computer. In both cases, you must use a 1.2MB drive to make
          the conversion. Try  using a  360K first  and only  switch to  a
          1.2MB disk if you get an  error on several disks. The disk  will
          be formatted  to 720K  capacity by  using the  area between  the
          tracks.

          Some computers will not recognize the converted disk. You'll  be
          able to do a DIR of it, but cannot read the actual files. If you
          encounter this  problem, use  the FIXFLOP.EXE program  included
          with DiskDupe.  This is  a  small memory-resident  program  that
          allows such computers to read this 5.25" disk.

          Note: If you are copying disks  to send to others, we  recommend
          making a  master for  each disk  size, rather  than using  track
          conversions. This allows  you to use  the full  capacity of  the
          disk  and  will  alleviate  any  possible  problems  that  other
          computers might have reading converted disks.

          Maintaining your Drives

          Dirty, misaligned drives are the primary cause of poor  diskette
          copy quality. Since dirty heads prevent data from being properly
          written, good  disks are  often  needlessly rejected  while  bad
          disks pass  through  error  detection  mechanisms  unnoticed.  A
          diskette produced on a misaligned drive will usually be readable
          on the same drive but not on properly aligned drives.

          How Often to Clean

          We recommend that you clean the drive heads every 500 disks,  or
          at least once a month. Sometimes in humid or dirty environments,
          you will need to clean the  heads every 100 disks. If you  start
          experiencing a lot of rejected disks or have other problems,  it
          is always a good idea to clean the heads.

          With DiskDupe,  you can  set a  counter to  remind you  when  to
          clean, as well as  align your drives. To  set the limit for  the
          counter, go into the Setup menu  and choose Global. The  default
          settings for Disks  between Cleaning  is 500  and Disks  between
          Aligning is 2000. Once you reach any of these settings, a  Clean
          or Align button  will appear on  the job screen,  as well as  an
          exclamation point (!)  next to  the appropriate  counter in  the
          Drive List dialog box.  Once the drive is cleaned or aligned, the
          counter will reset to 0 for that drive.



          When cleaning the drive, use a good wet-dry style cleaning  disk
          (you will need different kits for 3" and 5" drives).

          To clean the drive:

          1.   Select Drives  from  the Setup  menu,  and the  Drive  List
          dialog box will appear. (You can also press the Clean button, if
          it appears on the job screen, to access it directly.)

          2.   Highlight the drive to be cleaned and press Clean. DiskDupe
          will prompt you to insert the cleaning disk into the drive.

          3.   Apply the drops of cleaning fluid to the cleaning disk and,
          when  ready,     insert  it  into   the  drive.  DiskDupe   will
          automatically sense the  disk and will  clean the  drive for  15
          seconds.

          Quality vs. Speed

          This section provides advice  on how to  make the best  possible
          copies and how to speed up DiskDupe. There is always a  tradeoff
          between speed and quality  but with DiskDupe  you can achieve  a
          good balance.

          The main way to control quality and speed is with the Format and
          Verify options.

          Format Option

          A good, all-purpose  setting for  Format is  Only if  Necessary.
          DiskDupe will  detect  if disks  have  been formatted  and  take
          advantage of it for faster copies. If any part of the disk needs
          formatting, DiskDupe will detect it and switch into format mode.
          This works especially well for a combination of preformatted and
          new disks.

          If you are formatting new disks you can set Format to Always  to
          save the few  seconds that DiskDupe  normally takes to  identify
          that a disk  is blank and  shift into Format  mode. Also if  you
          want to reformat old disks, set it to Always.

          If you're using disks that you know have been formatted, you can
          set Format to  Never to  save time.  With Format  set to  Never,
          DiskDupe will  reject as  ``bad''                                           any  disks that  haven't  been
          formatted, so  you can  also use  this setting  to separate  out
          unformatted disks from a mixed stack.

          Verify Option

          The Verify  Option  lets  you  select  how  carefully  you  want
          DiskDupe to check the disks being copied for defects.  Normally,
          Verify is set to  Always. This will make  sure that all  defects
          are detected. However, if you are using preformatted disks  that



          you know are good,  you can set Verify  to Only After Format  to
          speed up duplication. You shouldn't  set Verify to Never  unless
          you plan to  compare every  disk in  a separate  pass using  the
          Compare option under the Go menu.

          Reject Rates

          In most  batches of  disks, depending  on the  quality, you  can
          expect about 2% to 4% to be bad  on the first pass. If you  want
          to use only the highest quality disks, you can throw these away.
          You can put the  disks through again and  usually about half  of
          them will pass the  second time. These disks  will be almost  as
          good as the  ones that  passed the first  time. Once  a disk  is
          rejected twice, it is best to throw it away.

          You can use low cost disks with DiskDupe and still be  confident
          it will catch any bad disks. Make sure, however, that the Verify
          option is set to Always.

          Quality Considerations

          There are several steps you can take to ensure that your  copies
          are perfect. If you still get a significant amount of bad  disks
          after following these suggestions,  you might consider  changing
          to a different brand of disks.

          - Make sure  your computer operates  properly with DiskDupe.  To
          check your computer, go into Drives in the Setup menu and  click
          on Test. For further information, refer to Testing Your Setup in
          the chapter on Setting Up Your Computer. As an additional  test,
          copy several  different  5.25" and  3.5"  master disks  and  use
          DiskDupe to compare each  master disk to  its copy. If  DiskDupe
          doesn't report any  errors, your  computer will  work well  with
          DiskDupe.

          - Avoid using a 5.25" 1.2MB drive to copy 360K disks, if at  all
          possible. Since the 1.2MB  drive writes a  smaller track than  a
          360K drive, some  360K drives  will have  problems reading  360K
          disks written in that drive.

          - Clean your disk drives frequently.  Drives need to be  cleaned
          about every 500 disks or at least once a month.

          - Make  sure your  drives are  properly  aligned. If  a  drive's
          read/write head  is  out  of  alignment,  it  will  be  able  to
          duplicate and  read the  disks it  copies with  no problem,  but
          other drives  may  not  be  able  to  read  these  disks.  Drive
          diagnostic kits  are  available  that  will  measure  the  drive
          alignment directly. The alignment should be checked every  2,000
          disks or at least once a year.



          - If you buy preformatted disks,  be sure that Verify under  the
          Format/Verify option  in the  Job menu  is  set to  Always.  The
          quality of preformatted disks varies greatly.

          - After  you  duplicate disks  on  one drive,  compare  them  on
          another. Sometimes you will want to  compare 100% of the  disks,
          but usually comparing 5% to 10% of the disks is enough to  alert
          you to any problems.

          Even if your disks are duplicated perfectly, after you mail them
          to someone else,  you can  expect about  1% of  them to  develop
          problems. A  lot of  damage is  done  to disks  during  mailing,
          mainly due to  magnetic fields produced  by the  motors used  in
          conveyer belts  and sorting  equipment.  Also many  people  have
          dirty or misaligned drives that  will have problems reading  any
          disks besides their own.

          Viruses

          Viruses rank  among a  computer's deadliest  enemies,  infecting
          programs and  depositing themselves  in  your hard  disk's  boot
          sector. When virus-ridden programs and disks are run on  another
          computer, that machine is stricken as well.

          DiskDupe is  a  natural deterrent  to  viruses. Since  it  works
          directly with your computer's hardware, DiskDupe will not spread
          viruses from  an  infected  computer to  the  copies  it  makes.
          However, if a disk that DiskDupe is copying is already infected,
          the copies will be as well. Since DiskDupe images are stored  as
          data files, they are not susceptible to virus infection, even if
          your system is later infected by  a virus. However, images  made
          from virus-ridden disks will contain the virus.

          Commercial software  such as  Norton  Anti-Virus, PC  Tools  and
          McAfee Viruscan can check for and remove viruses from your  hard
          and floppy disks.

          Optimized Master Disks

          If files have been  erased from a disk,  DiskDupe may be  fooled
          into thinking that  there is more  data on the  disk than  there
          really is. To help DiskDupe work most efficiently, it is best to
          use a newly formatted disk as your master disk.

          DiskDupe is able to sense which part of the disk has valid data
          on it and only duplicate  that part of the  disk. If you have  a
          master disk which has had many different files copied to it  and
          then erased, DiskDupe  will have  to duplicate  the entire  disk
          even though all  of the disk  might not contain  real data.  The
          copies will still be good, but the duplication will take  longer
          than necessary.



          To make  a blank  master disk,  first format  a disk  using  the
          DiskDupe Format  command with  Format set  to Always  under  the
          Format/Verify option. Then use the Dos Copy command to copy  the
          necessary files onto this newly formatted disk. This master disk
          is now clear of extraneous data.

          Note: If you format  your master disks with  the Dos 5.1  format
          command, use the FORMAT /U option to erase the entire disk. This
          will enable DiskDupe to make fast copies of this disk.

          Duplicating Times

          The following  table gives  you an  indication of  the  relative
          speed of  various copying  combinations. Ideally,  it's best  to
          always verify and compare each disk.  Since this isn't always  a
          realistic proposition, the following table can help you  balance
          the trade-offs between quality and speed.

          Notes:

          - If your disks are not completely full, duplicating times  will
          be faster than this.

          - For  information regarding  copying times  with various  speed
          drives see the on-line help under Index, Duplicating Times.

          Trouble Shooting

          Common Problems

          Problem: After I copy a disk using DiskDupe and then try to do a
          DIR on it, I get an error reading the disk.

          Solution: Take the disk out of the drive. Type <Ctrl-C>  several
          times and put the disk back in.

          Problem: I am trying to copy 360K disks on my computer and it is
          not working.

          Solution: Make  sure you  have your  A: drive  set up  correctly
          (usually as a  1.2MB drive)  and that the  copy type  is set  to
          360K.

          Problem: DiskDupe works perfectly on  my computer, but gives  me
          an error on my laptop.

          Solution: Some laptops have a battery saving feature that  turns
          off the DMA chip. Turning off this feature when you use DiskDupe
          should solve the problem.

          Problem: I keep getting a 909 DMA Setup error.



          Solution: DiskDupe is trying to allocate some memory to set up a
          DMA buffer, but  it cannot allocate  any because  memory may  be
          fragmented (this usually happens when running from Windows).

          Try starting DiskDupe  by typing DISKDUPE  /DMAWIN=OFF from  the
          Dos prompt.  This setting gets saved in the DISKDUPE.DAT file so
          it does not have to be reentered each time afterwards.

          Alternately you  could try  increasing the  DMA buffer  size  by
          adding the line "DMABufferSize=100"  under the [386Enh]  section
          of the Windows SYSTEM.INI file if you are running DiskDupe  from
          Windows.

          Software Compatibility

          This  section  provides  remedies  to  difficulties  that   some
          computers experience  when  running  DiskDupe.  If  you  have  a
          problem running  DiskDupe  that  matches  one  or  more  of  the
          descriptions below, you may want to try the suggestion given  to
          see if it  improves performance or  eliminates the problem.  Try
          these only if you experience problems.

          - Windows 3.1: If  you get  an error  message indicating  a DMA
          problem,  add  the  line  DMABufferSize  =  64  to  the  Windows
          SYSTEM.INI file under the [386 Enh] heading in the file.

          - Windows 3.1:  When running in  386 Enhanced  Mode and  Windows
          reports a ``                     Program Violates System Integrity ''                                                         message when you
          click on the DiskDupe icon, create a PIF file for DiskDupe  with
          EMS KB Limit set to 0. This occurs when early versions of EMM386
          are used with the /NOEMS parameter.

          - QEMM and SmartDrive 3.1: If QEMM reports an error with its DMA
          buffer, use  the line ``QEMM386.SYS DB=3 DMA=15'' to load  QEMM.
          The DB=3 parameter allocates 3k for  the disk buffer and  DMA=15
          allocates 15k for  the DMA  buffer. This  sometimes occurs  with
          SCSI hard disks.

          - OS/2: To get maximum speed, open the Dos settings box for the
          DISKDUPE.EXE object.  You'll need  to set  HW_TIMER to  Off  and
          IDLE_SENSITIVITY to 100 for the Dos session.

          Other MSD Products

          Besides the  DiskDupe software,  Micro System  Designs offers  a
          complete line of other products to  help you automate your  disk
          production. For a brief description  of these products, see  the

          your local DiskDupe dealer.

          Allegro Mini



          A floppy controller card that is up to  40% faster, guarantees a
          higher quality copy, supports up to four 2X (Double Speed) drives,
          and is easier to install than a regular controller card. The Allegro
          Mini gets its speed by formatting and writing in the same revolution,
          which increases the copy quality by eliminating the write splices
          between each sector.                               Recommended for  DiskDupe Pro  and DiskDupe
          Auto and AutoPro  users with 1X  (Single Speed)  and 2X  (Double
          Speed) drives.

          Allegro I

          A floppy controller card that has the same quality, speed and ease-
          of-installation as the Allegro Mini, but supports SDS (Simultaneous
          Double Sided) and 2XSDS (Double Speed Simultaneous Double Sided)
          drives. Recommended for DiskDupe AutoPro users with SDS and 2XSDS
          drives.

          Allegro II

          An enhanced version of the Allegro I, the Allegro II offers all the
          features of the Allegro I and more. The Allegro II supports 4XSDS
          (Quad Speed Simultaneous Double Sided) drives.  It has a special 2.2
          Rev Turbo Mode setting that can further increase copy times.  It's
          software auto-configurable, and contains support for a special PLL
          (Phase Lock Loop) Window Margin chipset upgrade that can help catch
          marginal quality disks before they get out the door. Recommended for
          DiskDupe AutoPro users with SDS, 2XSDS and 4XSDS drives.

          DupeJet

          The DupeJet is a manual duplication system including a high speed
          drive, controller and software that can copy up to 300 disks per
          hour. The components used are the same that professional duplicators
          use, so you are assured of the highest quality copies.
