                         SDEFRAG/OPTIMIZER ERROR 101
                          (Applies to Stacker 4.0)

      BACKGROUND
      
      If you receive error 101 while optimizing your Stacker drive,
      your system does not have enough memory to run the SDEFRAG
      utility. Although the Optimizer uses XMS memory, if available, it
      still requires some minimal amount of conventional DOS memory
      (the first 640K) to run. You must increase the conventional
      memory available on your system, and/or reduce SDEFRAG's memory
      requirements.
      
      SOLUTION

         - Increase conventional memory available.
         - Reduce SDEFRAG's memory requirements.
           
      Increase conventional memory available
      
      There are two methods of increasing your conventional memory,
      automatic or manual. Third party memory managers such as QEMM,
      386MAX, NETROOM, or MS-DOS's MEMMAKER are examples of programs
      which will automate the memory management process. Running a
      program such as these often will increase available conventional
      memory to the point where the Optimizer will run successfully.
      
      If an automated memory manager is not available, or it does not
      provide sufficient conventional memory, you may try using a
      simple memory configuration by manually editing your CONFIG.SYS
      file. This procedure will require DOS 5 or above. Note that if
      you have DOS 6 or above, you may press the F8 key when you get
      the message "Starting MS-DOS" when starting your computer. This
      will allow you to select which lines of the CONFIG.SYS to run.
      
       1.  From the STACKER directory DOS prompt, type ED /C <enter>
       2.  Remark out (make inactive) every line in your CONFIG.SYS by
           typing REM <space> at the beginning of each line, except for
           the following lines:
           DOS=HIGH,UMB
           DEVICE=C:\<DIR>\HIMEM.SYS
           DEVICE=C:\<DIR>\EMM386.EXE <NOEMS or RAM>
           Where <DIR> is DOS or WINDOWS.
           (Note: For DOS 6 or greater use the DPMS and STACHIGH lines
           below)
           DEVICE=C:\STACKER\DPMS.EXE
           DEVICEHIGH=C:\STACKER\STACHIGH.SYS
           (Note: For other versions of DOS use the Stacker lines that
           will appear something like these)
           DEVICEHIGH=C:\STACKER\STACKER.COM
           DEVICE=C:\STACKER\SSWAP.COM (this line may not appear)
       4.  Save the file and restart the computer.
       5.  Run the Stacker Optimizer. If it runs successfully, restore
           your CONFIG.SYS file to its original configuration and
           restart your system.
           
      Reduce SDEFRAG's memory requirements
      
      If the procedures above still do not allow the Optimizer to run,
      you may lower its memory requirements. You may run SDEFRAG with a
      special option. This option affects speed, but allows it to run
      in less memory. From the DOS prompt, type:
      
            SDEFRAG /buffer=#
      where # is a value between 256 and 4096, inclusive. By default,
      SDEFRAG normally runs at /buffer=4096. Smaller numbers use less
      memory. If you have XMS memory available, try using /buffer=1024
      first.
      
                                    Note
      If you received the error message while trying to grow or
      shrink the Stacker drive, run the Optimizer by typing
      SDEFRAG /buffer=nnn /GP <enter>.  If you received the error
      message while trying to change the Expected Compression
      Ratio (ECR), run the Optimizer by typing SDEFRAG /buffer=nnn
                                /GL <enter>.
