You Must Use "DBLSPACE /FORMAT A: " to Format That Drive (108750)

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.
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.
To work around this problem:
• Change to the drive letter that contains the compressed floppy disk
(usually A: or B:) by typing A: or B:.
• Type dblspace /unmount <x>: where <x> is
the floppy disk drive letter.
• Type format <x>: where <x> is the floppy
disk drive letter.
