DoubleSpace Maintenance Program Does Not Display All Drives

SYMPTOMS

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.

When you compress an existing drive or create a new compressed drive using the DoubleSpace maintenance program, some of your drives may not appear in the list of available drives.

CAUSE

The DoubleSpace maintenance program does not display drives that do not have sufficient free space to be compressed.

RESOLUTION

To work around this problem, ensure the disk you want to compress has enough free disk space. To determine how much space is required, refer to the following table:

   Disk Type                                     Free Space Required
   ---------                                     -------------------

   Non-Boot Disk (compressed from command line)        1.13 MB
   Non-Boot Disk (compressed from                      1.13 MB
                  DoubleSpace Manager)
   Boot Disk (compressed from command line)            1.45 MB
   Boot Disk (compressed from command line)            1.63 MB
   Floppy Disk                                         1.10 MB
                

NOTE: MS-DOS 6.2 Help contains incorrect numbers for free space required if you are attempting to compress a boot disk.

For more information, type help dblspace /compress at the MS-DOS command prompt and then press ENTER.
