SYMPTOMS
========

When you try to mount a DoubleSpace-compressed removable media disk, you receive
the following error message:

  Dblspace cannot mount drive <letter>: The <letter>:\Dblspace.000
  file is not a valid compressed volume file. To fix it, type scandisk
  <letter>:\Dblspace.000 at the command prompt.

If you run ScanDisk, it will likely report no errors.


CAUSE
=====

This problem occurs when the DoubleSpace-compressed removable media disk is
write protected.

RESOLUTION
==========

To work around this problem, remove the write protection from the removable
media disk.

STATUS
======

Microsoft has confirmed this to be a problem in MS-DOS DoubleSpace version 6.2.
We are researching this problem and will post new information here in the
Microsoft Knowledge Base as it becomes available.
