After you use any version of Symantec Norton Speed Disk prior to version 7.0 on a compressed DoubleSpace drive, the DBLSPACE /CHKDSK command may report a very large number of lost allocation units.

This occurs when you have set the option to Clear Unused Disk Space and then perform a full optimization.


To correct this problem, type the following at the MS-DOS command prompt and then press ENTER:

dblspace /chkdsk /f

NOTE: The Compress program from PCTools versions 5.5 and 6.0 may also cause the above problem if the Clear Unused Disk Space option is set when you perform a full optimization.
