Title: Using SREMOVE To Remove a Stacker Drive Completely
STAC FAX Index #2601 - 5/15/92                          
___________________________________________________________________________

Background.

   All of the data, files, and free space for a Stacker drive are contained 
   in a file named STACVOL.xxx.  Stacker's SREMOVE utility removes a Stacker 
   drive by deleting the STACVOL.xxx file associated with that drive.  This 
   process will remove all data in the drive.  Therefore, it is recommended 
   that you back up the data you wish to keep. See STAC FAX index #2404 
   "Backing Up Stacker Drives" for more information on backing-up 
   a Stacker drive. 
   
Removing the Stacker drive.   

   Removing the Stacker drive is a two part process.  First, you need to  
   remove the reference for the drive's STACVOL file from the Stacker 
   device driver in Config.sys.  Then run SREMOVE to remove the drive.
   
   For example, to remove Stacker drive D: first use the SEDIT text editor 
   to modify Config.sys.  Type: 

        C:\STACKER\SEDIT.COM C:\Config.sys    <Enter>

   You should now see a listing of the Config.sys contents.  Locate the 
   Stacker device drivers.  They will look similar to:

        DEVICE=C:\STACKER\STACKER.COM  C:\STACVOL.DSK  D:\STACVOL.DSK  
        DEVICE=C:\STACKER\SSWAP.COM    C:\STACVOL.DSK /SYNC
        DEVICE=C:\STACKER\SSWAP.COM    D:\STACVOL.DSK 

   Now remove the STACVOL.DSK file reference for drive D:  The device drivers
   will now be:

        DEVICE=C:\STACKER\STACKER.COM  C:\STACVOL.DSK   
        DEVICE=C:\STACKER\SSWAP.COM    C:\STACVOL.DSK /SYNC
   
   Press <CTRL> Z to save the Config.sys file.

   The last step is to run SREMOVE to delete the Stacker drive.  Type:

        C:\STACKER\SREMOVE D:

   NOTE: You must run SREMOVE from a drive other than the one you wish to
         delete.  
   
   SREMOVE will produce a message similar to the following:
   
   -------------------------------------------------------------------
   SREMOVE - 2.0, (c) Copyright 1990-92 Stac Electronics, Carlsbad, CA
   
                1637 files/directories found on drive C.

                !!! ALL DATA ON DRIVE C WILL BE LOST !!!

   ARE YOU ABSOLUTELY CERTAIN YOU WANT TO REMOVE DRIVE C? ["yes"/no]: 
   -------------------------------------------------------------------

   Type "yes" to procede.  Reboot for the removal to take affect.        

What if I SREMOVE the drive, then change my mind?

   Because the Sremove process simply deletes the Stacvol file for that 
   drive, it is possible to use an Undelete or Unerase utility to recover 
   the drive, (if none of the clusters used by the file have been rewritten). 
   For example, to undelete the Stacvol.xxx with DOS 5.0 type:  
   
            C:\DOS\Undelete    
   
   The undelete program will prompt for the first letter of the ?TACVOL 
   file.  Enter 'S' (without the quotes).  If the file is successfully 
   undeleted, the program will tell you.
