                             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
        
        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.
