                   CONVERTING REMOVABLE DOUBLESPACE DISKS

      BACKGROUND
      
      Stacker’s Setup converts only mounted, fixed DoubleSpace drives.
      However, Stacker’s DCONVERT program easily converts a removable
      disk, such as a floppy disk, a Bernoulli, or a SyQuest.
      
      The following procedure assumes you've already installed Stacker.
      
      SOLUTION
      
      For this example, let's assume that Drive G: is a Bernoulli drive
      that was compressed with DoubleSpace. In the conversion
      procedure, you will check the drive for any pre-existing
      problems, run a program called DCONVERT to convert the drive, and
      then mount the new Stacker drive.
      
      NOTE: Because it is not yet a Stacker drive, Drive G
      does not appear in Stacker's drive map.

      Check for any pre-existing problems
      
       1.  If you are in Windows, exit to DOS. The procedure works only
           under DOS.
       2.  Insert the removable disk into its drive.
       3.  Check the drive for any pre-existing problems. At the DOS
           prompt, type:
              CHKDSK G: <Enter>
           Let the DOS CHKDSK utility fix any problems it finds.
      
      Convert the drive to a Stacker drive
      
       1.  Find the name of the compressed volume file by typing:
              DIR G: /AH <Enter>
       2.  Look for a filename such as DBLSPACE.000. Note the name to
           use in the next step.
       3.  Type:
              DCONVERT /C G:\DBLSPACE.000 <Enter>
           where DBLSPACE.000 is the drive to be converted to a Stacker
           drive.
                                      
                                 IMPORTANT!
                                      
                  DO NOT INTERRUPT THE CONVERSION PROCESS!
                   If you do not let DCONVERT finish, you
                               may lose data.
                  
      
      Mount the new Stacker drive
      
      DCONVERT converts the drive into a Stacker drive. The name of
      Stacker's "volume file" is STACVOL.DSK.
      
       1. Ensure the removeable disk is in its drive.
       2. From the DOS prompt, type: CONFIG <enter>.
       3. Allow the program to make changes to your STACKER.INI file.
       4. Restart your computer.
           
      Recompress your data with the Stacker Optimizer
      
       1. At the DOS prompt, type:
              STAC <Enter>
       2. Choose Stacker Optimizer.
       3. Select the drive you want to recompress.
       4. Choose Full-MaxSpace.
      Stacker recompresses the data on the selected drive.
