      STACKER NOTE                                         STACKER NOTE
                     REBOOT DURING SDEFRAG, NOT MOUNTED
                    (Applies to all versions of Stacker)

      BACKGROUND
      
      When Stacker mounts a Stacker drive it verifies the STACVOL file
      containing the compressed data.  If the Stacker Optimizer
      (SDEFRAG) was interrupted during the "Writing New directories..."
      stage of optimization, Stacker pauses the normal startup of your
      computer with this message until the problem is corrected:
      
        E: = C:STACVOL.DSK Reboot during SDEFRAG detected - NOT MOUNTED
        Press any key to continue...
      
      SOLUTION
      
        Determine the name of the STACVOL file
        Run SDEFRAG to repair the drive
           
      Determine the name of the STACVOL file
      
      From a DOS prompt, type STACKER and press <Enter>.  Take note of
      the unmounted STACVOL file (E:\STACVOL.DSK in this example):
      
           Drive C: was drive E: at boot time [E:\STACVOL.DSK - Not
              mounted]
              
      Run SDEFRAG to repair the drive
      
       1. Insert Stacker disk 2, change to that drive, and type one of
          the following:
      
                              (For Stacker 2.0 and 3.0)
              SDEFRAG /Fdrive:\STACVOL.XXX
                              (For Stacker 3.1)
              SDEFRAG /RESTORE=drive:\STACVOL.XXX
      
          where drive:\STACVOL.XXX  is the name of the STACVOL file
          you determined in the previous step.  There is no space
          between /F and the drive letter.
       
       2. Let SDEFRAG repair the Stacker drive and restart your
          computer.
