APPLIES TO

  • Microsoft MS-DOS 6.2 Standard Edition



This article was previously published under Q108750

SYMPTOMS

If you unmount a compressed volume file (CVF) on a floppy disk drive and then try to use the MS-DOS FORMAT command to format a floppy disk, you may receive the following message

You must use "DBLSPACE /FORMAT <X>:" to format that drive.

where <X> is the floppy disk drive letter.

CAUSE

This message is caused by the new Automount feature in MS-DOS 6.2. Any command that attempts to access a floppy disk drive containing a disk with a CVF mounts that CVF.

RESOLUTION

To work around this problem:

  1. Change to the drive letter that contains the compressed floppy disk (usually A: or B:) by typing A: or B:.
  2. Type dblspace /unmount <x>: where <x> is the floppy disk drive letter.
  3. Type format <x>: where <x> is the floppy disk drive letter.
