-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft MS-DOS operating system versions 6.0, 6.2, 6.22 
-------------------------------------------------------------------------------

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" (without the quotation
marks) at the MS-DOS command prompt and then press ENTER.
