DRVSPACE /DELETE -- Note

If you accidentally delete a compressed drive, you might be able to restore
it by using Microsoft Undelete. When DriveSpace deletes a compressed drive,
it actually deletes a file on your uncompressed drive. This file is called
the "compressed volume file". A compressed volume file has a filename in the
form DRVSPACE.xxx (for example, DRVSPACE.000).

First, restore the deleted compressed volume file by using Undelete. Once
you have restored the file, remount it by using the <DRVSPACE /MOUNT>
command. If DriveSpace cannot remount the compressed volume file, run
<ScanDisk> on that compressed volume file.

For information about using Microsoft Undelete, see the chapter "Managing
Your System" in the MS-DOS User's Guide.
