     STACKER BOOT TIME ERROR MESSAGES

     MESSAGE

     X: = Y:STACVOL.xxx Cannot find STACVOL file - NOT MOUNTED

     Explanation:   This message suggests that a STACVOL.xxx file
                    has been deleted or the STACKER.INI is
                    incorrect.

     Action:        If the STACVOL.xxx file has been deleted, the
                    STACVOL.xxx file may remain UNDELETED as long
                    as you have not written additional data on to
                    the drive that contained the STACVOL.xxx
                    file.  Otherwise, UNDELETE will not be able
                    to recover the STACVOL.xxx file because a
                    portion of it has been written over.

                    The STACKER.INI may be searching for a
                    STACVOL.xxx file on the wrong drive.  Check
                    the STACKER.INI file to make sure each line
                    that loads a STACVOL.xxx file points to a
                    drive that actually contains a STACVOL.xxx
                    file.

                    Example: /C:\STACVOL.XXX,SW


     MESSAGE

     X: = Y:STACVOL.xxx Updating Stacker allocation map...OK

     Explanation:   This message suggests that the data on a
                    compressed drive does not correspond to
                    Stacker's internal table for keeping track of
                    where that data is located.


     Action:        Do nothing.  Stacker will adjust this
                    automatically.


     MESSAGE

     !!! Stacker not found to relocate - nothing done.

     Explanation:   This message indicates that the STACKER.BIN
                    device driver is not loaded and cannot be put
                    into Upper Memory by the STACHIGH device
                    driver.

     Action:        The STACKER.BIN device driver needs to be in
                    the root directory of the bootable partition.
                    STACKER.BIN has the (R)ead only, (H)idden,
                    and (S)ystem attributes attached to it.

                    You can reinstall STACKER.BIN by SYSing the
                    boot partition using a Stacker aware boot
                    disk (with SYS on the disk).

                    Or you can build STACKER.BIN by combining
                    STACLOAD.BIN and STACKER.COM files using the
                    following command:

                    COPY /B STACLOAD.BIN + STACKER.COM
                    STACKER.BIN

     STACKER RUN TIME ISSUES


     MESSAGE

     No error during bootup. After bootup a DIR on the compressed
     drive does not list the files that should reside there.

     Explanation:   This suggests that the STACKER.INI file is
                    bad or missing.

     Action:        Check the root directory for a (H)idden
                    STACKER.INI file.  If it does not exist,
                    create one as such the following:

                    /P=1
                    /DIR=C:\<Novell DOS 7 directory name>
                    /X:\STACVOL.xxx,sw  

                    where <Novell DOS 7 directory name> is the
                    name of the directory that contains your
                    Novell DOS 7 files.

                    where /X is the drive that contains a
                    STACVOL.xxx file.  This line would be
                    included for each of the drives that contain
                    STACVOL.xxx files.

     MESSAGE

     UNSTACK gives the message "Unable to open STACVOL file
     x:\STACVOL.DSK for verification.


     Action:   Check to see that the drive that contains the
               STACVOL file has not been overwritten by a network
               drive.  Log out and run UNSTACK again.

     STACKER MAINTENANCE ISSUES

     Third-Party Surface Scan and Fix

          Run all surface scan and fix programs on the
          uncompressed portion of a Stacker drive (drive
          containing STACVOL.xxx) without the Stacker drivers
          loaded.

          If an error is found within the STACVOL.xxx file, do
          the following:

          1.   Exit the surface program.
          2.   Remove the attributes on the STACVOL.xxx file.
          3.   Run the surface scan on the drive again and allow
               it to fix any problems.
          4.   Return the attributes to the STACVOL.xxx file
               (+RSH).
