      STACKER NOTE                                         STACKER NOTE
                            MOUNT ID WRITE ERROR
                 (Applies to Stacker 3.1 for Windows & DOS)

      BACKGROUND
      
      If the Stacker device driver cannot successfully write the Mount
      ID to a STACVOL file on a Hard Card, you will get the error
      message "Mount ID Write Error" when you start your computer.
      
      SOLUTION
      
          Manually remove write protection
          
          Verify the position of STACHIGH.SYS in your CONFIG.SYS
          file
          
          Add a line to AUTOEXEC.BAT to automatically remove write
          protection
          
          Install the updated Stacker files
          
          Remove the line from your AUTOEXEC.BAT file
           
      Manually remove write protection
      
       1. To remove write protection so that you can change your
          computer's configuration, at the DOS prompt, type:
                   
                   C:\STACKER\CHECK drive: /F /B <Enter>
          
          where drive is the letter of the write protected drive.
           
      Verify the position of STACHIGH.SYS in CONFIG.SYS
      
       1. Edit your CONFIG.SYS file.
       
       2. Ensure that the line that ends with "...STACHIGH.SYS"
          appears after your Hard Card's device driver.  If
          STACHIGH.SYS loads first, then move your Hard Card's device
          driver above it.  For example:
      
                   DEVICE=<Hard Card device driver>
                   DEVICEHIGH=C:\STACKER\STACHIGH.SYS
      
          Note:  If SETVER.EXE appears in your CONFIG.SYS file, ensure
          that it loads after STACHIGH.SYS.
       
       3. If you modified your CONFIG.SYS file, save the changes.
           
      Add a line to AUTOEXEC.BAT to automatically remove write
      protection
      
       1. Edit your AUTOEXEC.BAT file.
       
       2. Add this line to the beginning of the file:
                   
                   C:\STACKER\CHECK drive: /F /B
          
          where drive is the letter of the write protected drive.
       
       3. Save the file and exit to DOS.
       
       4. Restart your computer.  Stacker will display the Mount ID
          write error and prompt you to "Press any key to continue..."
       
       5. Press any key.  Write protection will be removed by the new
          line in AUTOEXEC.BAT, and your computer will start normally.
          Note:  your computer will boot in this way until you
          complete the next two steps.
           
      Install the updated Stacker files
      
       1. Run setup from disk 1 to install the updated Stacker files.
          Follow the Setup screens, and choose RESTART when prompted
          at the "Setup/Upgrade Complete" screen.  Your computer will
          start without the Mount ID write error.
           
      Remove the line from your AUTOEXEC.BAT file
      
       1. The line you added earlier is no longer necessary.  Edit
          your AUTOEXEC.BAT file and delete the line:
              
              C:\STACKER\CHECK drive: /F /B
       
       2. Save the file and exit to DOS.
       
       3. Restart your computer.
