DoubleSpace Doesn't Support Logical Drive B on Single Floppy (104889)

The information in this article applies to:
    Microsoft MS-DOS operating system 6.2
    Microsoft MS-DOS operating system 6.22

This article was previously published under Q104889


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.

DoubleSpace does not work correctly if you mount two DoubleSpace- compressed floppy disks on drive letters A and B if you only have one physical floppy disk drive.


If you have one floppy disk drive (A) but can access it as A or B, you will encounter problems with DoubleSpace if you manually mount a DoubleSpace-compressed floppy disk on both drives A and B.

NOTE: The DoubleSpace Automount code disables itself for logical drive B if you have only one floppy disk drive.

To avoid this problem, do not use the logical drive B to manually mount a DoubleSpace-compressed floppy disk.
