            17.1   DISK COPY PLUS


            "I really find your DISK COPY PLUS a very very fine program. It
            literally has saved me a lot of time copying diskettes."
                                            -----   one user, United States


            DISK COPY PLUS is the professional version of DISK COPY FAST.
            It includes all the features of DISK COPY FAST plus some
            advanced features.


            To many people, large quantity diskette duplicating means that
            you need to buy high-price copier. Not so any more. With DISK
            COPY PLUS you can assemble two low-end 286 PCs each equipped
            with up to four floppy drives at much lower price and achieve
            much higher copying speed. Not only do You get higher
            productivity, but also that you get two computers instead of a
            special purpose machine.


            DISK COPY PLUS is even better for you if you only need to copy
            a small quantity of the same source diskette every day.
            Consider the low cost, incredibly high speed (see section 10 in
            DCF42.DOC) and other powerful features (explained later), DISK
            COPY PLUS is hard to beat.


            One of the most powerful features of DISK COPY PLUS is
            customized hot keys. You define up to 10 hot keys according
            to your special needs.


            A feature similar to hot keys but requiring no keystrokes is
            the AUTOEXEC feature. You define what DISK COPY PLUS should do
            automatically when you run the program, just like AUTOEXEC.BAT
            does when you reboot your computer.


            For example, DISK COPY PLUS can be configured so that each
            time you type DCP at the DOS prompt it will read an image file,
            set up a serial number (explained later), define read/write
            options and then prompt for the target disk. You then insert



      DISK COPY FAST    Copyright 1992, 1993    Chang Ping Lee       page 28






            the target into drive A:, close the door and it will start
            copying. After you have done with one format, at the press of
            one key it converts the source to another format, say, from
            720KB to 360KB, and continue copying in another drive.


            In this example, it takes only two keystrokes (one to change
            format, another to quit.) to produce as many 360KB and 720KB


            target diskettes as you like. Each copy produced can have a
            unique serial number and each copy can be double checked with
            a BYTE-BY-BYTE comparison to make sure they are identical to
            the original, except for the serial number.


            This high degree of automation means that you can save time for
            more creative work, or you can hire someone who knows nothing
            about computers to do the copying for you.


            Another nice feature of DISK COPY PLUS is automatic serial
            number assignment. Some people like to change the disk serial
            number that DOS shows you when you use the DIR command. Other
            people like to imbed a unique serial number in their product.
            DISK COPY PLUS allow you to do either or both types of these
            serial numbers. In addition, it provides other tools to help
            you find and VERIFY the right location for imbedding serial
            numbers and show you the imbedded serial number on any
            duplicated diskette. This feature can be done automatically
            using the hot keys or AUTOEXEC features.


            DISK COPY PLUS also keeps track of serial number of EVERY
            image file for you so that you don't need to specify the
            serial number each time you run the program. It also keeps
            a log file for your diskette duplication. With a little
            editing (you add the distribution destination) the log file
            becomes a nice record of your diskette distribution.


            The power of DISK COPY PLUS keeps growing. Listed below are
            some other powerful commands.

            The DIAG command checks boot sector, file allocation table
            (FAT) and directory structure and provides reports for diskette
            usage and fragmentation.


            The CONVERT command convert diskette image from one format to
            another, so long as the data on original format can fit into
            the new format. For example, a 1.44 MB disk can be converted to
            360 KB diskette if the data on the 1.44 MB disk does not exceed
            the total data space on a 360 KB diskette.


            The DEFRAG command performs defragmentation on a diskette. It
            does more than just sectors swapping. The entire diskette is
            checked thoroughly for any possible way of compaction. The
            result is a perfect with no waste of space and no fragmentation.


            The DUMP command lets you move around the loaded diskette at
            very high speed. You can use it to check the contents of a
            diskette or verify the imbedded location(s) of a serial number.


            DISK COPY PLUS also provides commands that allow you to see
            the directory of a diskette, image file or diskette loaded in
            memory.

           17.2   DISK UTIL PACK


           "Your Disk Utility Package has many useful features. I was
           amazed by the copying speed of the F2H & H2F. They are time
           saving utilities. Great to use."     -----  one user, Singapore


           DISK UTIL PACK is a collection of five high performance and
           useful diskette utility programs. For example, the author uses
           H2F every day for filling orders for DISK COPY FAST and related
           products.


           F2H  (Floppy to Hard disk)

           A utility to copy a diskette to hard disk or RAM disk at very
           high speed. See the following table for benchmark results.


           H2F  (Hard disk to Floppy)

           A utility to copy recursively from current directory on hard
           disk or RAM disk to a diskette at very high speed. This program
           combined with F2H is ideal for backing up a small directory.
           See the following table for benchmark results.



                                 H2F vs XCOPY      F2H vs XCOPY
              --------------------------------------------------
               Case 1 (1.2MB)     8  vs  40         8  vs  17
               Case 1 (1.44MB)    9  vs  50         9  vs  19
               Case 2 (1.2MB)     9  vs  33         9  vs  18
               Case 2 (1.44MB)    8  vs  40         9  vs  19

               Note: (1) Case 1 contains 36 files and no sub directory.
                         Case 2 contains 13 files in 21 sub directories.
                         Total file size in both cases is about 300 KB.

                     (2) Performance varies on different system. The
                         above benchmark results is provided as an example,
                         NOT guarantee.

                     (3) The above results were measured with a RAM disk
                         on a 33 MHz 386 compatible system.

           FMT

           A utility to format 360KB, 1.2MB, 720KB and 1.44MB diskettes.
           Features include no keyboard operation, serial number assignment,
           label assignment and bad sectors handling.

           You type the program name at DOS prompt to start and press the
           ESC key to end, no keystroke in between!

           The serial number and label can be assigned incrementally with
           a text file which stores the serial number and label for the
           next diskette to be formatted. You can keep more than one text
           file for this purpose. Before exit, FMT will update the file
           automatically.

           Conventionally, a cluster is marked as bad cluster if the
           formatting program fails to access after three tries. FMT,
           however, adopts a more strict policy to ensure that your
           valuable data won't be saved on places which are bad or about to
           turn bad. FMT will try three times too. The difference is that
           if FMT fails to access a sector in the first try it will mark
           the sector bad and tell you how many tries has failed.


           CLN

           A utility to make full use of cleaning kits sold by 3M, Memorex
           and other companies.

           Without CLN, all you can do is to use commands such as DIR to
           get the disk drive moving and bring head into contact with the
           cleaning disk and the cleaning solution on it. However, there
           are two problems that only CLN can help you.

           Firstly, how many DIR commands you need to keep typing to keep
           the disk head in contact with the cleaning disk for 30 to 60
           seconds? With CLN you only need to type CLN to start and press
           the ESC to end the process, no keystrokes in between. CLN also
           "reads" both sides of every "track" to make full use of your
           cleaning kit. Try CLN once and you will know how many keystrokes
           it can save for you.

           Secondly, since there is no data on the disk DOS will stop after
           it fails to access the first track. This means you may only be
           using 0.625% of the surface of your cleaning disk! (There are 80
           tracks on a high density drive. Each track has two sides and you
           are only using one side on the first track.)



      DISK COPY FAST    Copyright 1992, 1993    Chang Ping Lee       page 32






           CLN not only forces your system to keep on "reading" different
           tracks on the cleaning disk and thus clean the head more
           thoroughly but also provides you simple and easy ways to verify
           that it does what it claims. Your will have the confidence that
           you give your diskette drive the best care possible.


           CHDK (CHeck DisKette)

           A utility which gives detailed information about a diskette. It
           shows you the information contained in the system area of the
           diskette, check the integrity of the system area, gives you
           detailed layout of system area, root directory and data area and
           then give you a report of the fragmentation on the diskette.

           The program also shows you other important or interesting
           information about a diskette. For example, it shows you the
           sectors, clusters and tracks with active data, maximum number of
           root directory entries.

           CHDK shows you lots of information packed in one screen.
