This information applies to both Microsoft DoubleSpace and Microsoft DriveSpace. For MS-DOS 6.22, use DRVSPACE in place of DBLSPACE for commands and filenames.



SYMPTOMS
If you copy a compressed volume file (CVF) to a DoubleSpace-compressed drive and attempt to mount the file, you receive the following messages:

DoubleSpace is mounting drive.

DoubleSpace cannot mount drive.

There is a disk error on drive. To fix it, type SCANDISK

at the command prompt.

For example, you receive this error if you copy DBLSPACE.001 to your compressed drive C and type dblspace /mount=1 c: at the MS-DOS command prompt. In addition, your drive C is unmounted.



CAUSE
DoubleSpace is not designed to support mounting CVFs from CVFs.



WORKAROUND
To work around this problem:


 * 1) Restart your computer to gain access to your compressed drive.
 * 2) Copy the CVF from your compressed drive to an uncompressed drive.
 * 3) Mount the CVF from the uncompressed drive.
