SYMPTOM:

If the DISKOPT of a Novell DOS 7.0 Stacker 3.12 drive either fails or
is aborted, an error message will be displayed on bootup. If for some
reason (either mechanical or user error) the DISKOPT of a Stacker
drive is interrupted, it may not mount on boot up.  One of the
following two error message will be displayed:

"E: = C:STACVOL.DSK Reboot during DISKOPT detected - NOT MOUNTED
Press any key to continue..."

"E: = C:STACVOL.DSK Reboot during DISKOPT detected - (Write
Protected)  Press any key to continue..."

SOLUTION:

Stacker Drive NOT MOUNTED

When Stacker mounts a Stacker drive it verifies the STACVOL file
containing the compressed data.  If the Stacker Optimizer (DISKOPT)
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 DISKOPT detected - NOT MOUNTED Press
any key to continue...

Determine the name of the STACKVOL file.  From the DOS prompt type
STACKER and press <Enter>.  Take note of the unmounted STACKVOL file 

     Drive C: was drive E: at boot time [E:\STACVOL.DSK - Not
mounted]  

Run DISKOPT to repair the drive

     DISKOPT /RESTORE=drive:\STACVOL.XXX

     where drive:\STACVOL.XXX is the name of the STACVOL file you
determined in the previous step. 

Let DISKOPT repair the Stacker drive and restart your computer.   

Stacker Drive WRITE PROTECTED

When Stacker mounts a Stacker drive it verifies the STACVOL file
containing the compressed data.  If the Stacker Optimizer (DISKOPT)
was interrupted during optimization, Stacker pauses the normal
startup of your computer with this message:

"E: = C:STACVOL.DSK Reboot during DISKOPT detected - (Write
Protected)  Press any key to continue..."

A CHKDSK on the drive reports: Disk D is currently write protected
because DISKOPT was interrupted while optimizing Drive D.  To remove
the write protection from Drive D run DISKOPT D:

Run DISKOPT to repair the drive

     DISKOPT D: 

     where D: is the write protected drive.  Select option "Perform
Repairs on Stacker Drive."  Let DISKOPT repair the Stacker drive and
restart your computer.
