If you are running STAC Electronics Stacker version 3.0 or 3.1 on your
computer, you may receive the following errors when you use the MS-DOS
DISKCOPY and FORMAT commands on floppy disks:
With DISKCOPY:
Formatting while copying
Drive types or diskette types not compatible
Copy process ended
Copy another diskette (Y/N)?
With FORMAT:
Existing format differs from that specified
This disk cannot be unformatted.
Proceed with format (Y,N)?
Parameter not compatible with fixed disk.
Format terminated.
Error reading partition table. Format terminated.
Extended error 21. Format terminated.
CAUSE
According to STAC Electronics, these problems are caused by Stacker's
AutoMount feature. If you remove a Stacker-compressed floppy disk and
insert an uncompressed disk in the same drive, you may be unable to
use the MS-DOS DISKCOPY and FORMAT commands on the uncompressed disk
until the drive is unmounted. In addition, a Stacker-compressed disk
must first be unmounted before it can be formatted with the MS-DOS
FORMAT command.
WORKAROUND
To work around these problems, first unmount the disk drive. This can
be done by typing stacker -x: at the
MS-DOS command prompt (where <x> is the letter of the floppy disk
drive) or by removing the compressed floppy disk from the drive and
rebooting the computer.
