      BACKGROUND
      
      When you compress a drive containing data, Stacker moves your
      files into a STACVOL file. During creation, the STACVOL file
      grows dynamically until it reaches full size. If the creation
      process ends prematurely, a size-mismatch will result. You will
      receive an error message when you restart your computer such as:
      
            E: = C:STACVOL.DSK (Size mismatch) (Write protected)
            Press any key to continue...
      
      NOTE: A size-mismatch on an operational Stacker drive requires a
      different solution. See Document 64982 "Size Mismatch, Existing
      Installation" for details.
      
      SOLUTION
      
         - Let AutoRecover restore the system, or
         - Manually restore the system, fix any disk errors, and
           recompress the drive.
         - What to do if you boot into Windows or a menu program.
           
      LET AUTORECOVER RESTORE THE SYSTEM
      
      Restart your system into DOS the same way you did when you ran
      Setup. Stacker 4.0 for OS/2 & DOS includes an automatic repair
      utility called AutoRecover. It will detect the error, announce
      the interruption of the Setup process, and will offer to either
      Uncompress the drive, restoring it to its original configuration,
      or to carry forward with the installation.
      
       1.  Accept Autorecover's recommendation. If it completes the
           Setup, you are finished. If it Uncompresses the drive,
           proceed to the steps below.
       2.  After the drive is uncompressed, examine it for problems or
           issues that may have caused the error. Run OS/2's CHKDSK
           against the drive. If it finds errors, run CHKDSK with the
           /F parameter.
       3.  Disable any anti-virus programs and caches and run the
           Stacker Setup again.
           
      
      MANUALLY RESTORE THE SYSTEM
      
           If AutoRecover does not invoke, do the following:
      
       1.  Insert Stacker Disk # 1 and go to that drive. At the prompt,
           type:
           UNCOMP DRIVE: <enter>
           where drive: is the drive that is compressed.
       2.  After the drive is uncompressed, examine it for things that
           may have interrupted the Setup. Run OS/2's CHKDSK against
           the drive. If it finds errors, run CHKDSK with the /F
           parameter.
       3.  Disable any anti-virus programs and run the Stacker Setup
           again.
           
      WHAT TO DO IF YOU BOOT INTO WINDOWS OR A MENU PROGRAM
      
      If you boot into Windows or into a menu program, you may not be
      able to perform the steps above because the write protection on
      the drive may prevent you from exiting to DOS. You will have to
      interrupt the boot process so that you can get to the DOS prompt.
      
       1.  If you are using MS or PC DOS version 6 or greater, restart
           the computer. Press the F5 key when you get the message
           "Starting xx-DOS...". When you get the Stacker error
           message, press the F5 key to continue. You will then be at
           the DOS prompt where you can execute the steps in the
           section above.
       2.  If you are using any other DOS version, restart the
           computer. When you get the Stacker error message, press any
           key to continue.
       3.  After the computer continues booting, press and hold the
           Ctrl key and tap the "C" key several times in rapid
           succession. If your timing is right, you will get the
           message:
           Terminate batch job (Y/N)?
           Respond "Y", and press enter. You will then be at the DOS
           prompt where you can execute the steps in the section above.
           (This method also works with DOS 6).
           
      Note: The secret to successfully interrupting the boot process is
      timing. The Ctrl-C key combination must be pressed while the
      AUTOEXEC.BAT file is executing. You may need to experiment a few
      times to get it just right.
