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 :" to format that drive.

where  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 : where  is the floppy disk drive letter.
 * 3) Type format : where  is the floppy disk drive letter.
