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:
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.
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.
Stacker 3.0 and 3.1 are manufactured by STAC Electronics, a vendor independent of Microsoft; we make no warranty, implied or otherwise, regarding these products' performance or reliability.
