      STACKER NOTE                                         STACKER NOTE
                      ERROR RUNNING NORTON DISK DOCTOR
              (Applies to Stacker 4.0 & Norton Utilities 7 & 8)
      STAC FAX  4408 (06-03-1994)
      -----------------------------------------------------------------
                                      
      BACKGROUND
      
      Disk repair utilities such as Symantec's Norton Disk Doctor (NDD)
      are not aware of Stacker's new SmartPack technology. If you run
      NDD against a Stacker 4.0 drive you will receive an error message
      that the Container Volume File for drive x appears to be
      seriously damaged or that the compressed volume is unsupported.
      NDD further recommends that you use the utilities provided with
      the compression program. However, you can run NDD against your
      Stacker drive if you skip compression tests.
      
      SOLUTION
      
      You may skip compression tests in two ways: from the command line
      or from the NDD menu.
      
       1.  If you start NDD from the command line, type: NDD /NOCOMP
           drive: <enter>. NDD will not give you the error message.
       2.  If you wish to turn off compression tests from the NDD menu,
           start the program as usual. From the main menu select
           Options. From the Options menu select General. Select Skip
           Compression Tests, then OK, and OK again to return to the
           main menu.
       3.  Run NDD as usual. NDD will not give you the error message
           about the seriously damaged Container Volume File.
       4.  Windows users: If you run NDD from Windows (Norton Utilities
           version 8), or have Norton Destop for Windows version 3, you
           may skip compression tests in the following manner:
           a. Open NDD. From the menu bar, select Option, then
           Preferences.
           b. Click on the box for Skip Compression Test.
           c. Click on OK to save the changes. Then run NDD on any
           drive you desire.
