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.


MIRROR may return the following error message when you try to use it on a small DoubleSpace-compressed drive:

Drive D: error.
The boot sector for this drive is incompatible with the MIRROR command. The mirror process was unsuccessful.


This problem occurs only if you try to use MIRROR on a very small (approximately 1-megabyte) DoubleSpace-compressed drive that you created by running DBLSPACE /CREATE (or by choosing Create New Drive from the Compress menu in the DoubleSpace maintenance program).


To work around this problem, run Mirror on the host for the compressed drive. To determine which drive is your host drive, type dblspace /list at the MS-DOS command prompt and then press ENTER.
