Under certain circumstances when you are running MS-DOS DoubleSpace,
Doublespace may not disconnect from a network drive correctly if the
network drive letter is between the last physical drive letter and the
host drive letter.
After you attempt to disconnect either from File Manager or MS-DOS,
the network drive changes to a floppy disk drive. If you choose the
floppy disk drive icon in File Manager, a message is displayed stating
that there is no floppy disk in the drive. If you choose the drive in
MS-DOS, the following message is displayed:
where <x> is the drive letter of the disconnected network drive.
File Manager and MS-DOS maintain this nonfunctioning disk drive until
you reboot your computer.
To work around this problem, do the following:
• Restart your computer.
• Change to your DoubleSpace host partition and use the ATTRIB
command to remove the hidden, system, and read-only attributes of
the DBLSPACE.INI file as follows:
attrib dblspace.ini -h -s -r
• Open DBLSPACE.INI in a text editor, such as MS-DOS Editor. You
should see two lines similar to the following (not necessarily in
• Change the ActivateDrive= statement's first parameter to the next
drive letter following your last physical drive letter. For example,
if you have two partitions (C and D) on one physical hard drive, set
ActivateDrive= to E.
WARNING: If you use the incorrect drive letters when you edit the
ActivateDrive= line in the DBLSPACE.INI file, the system may stop
responding (hang) when you restart it.
• Set LastDrive= to the same letter you used in step 4. As with the
previous example, if you have one physical drive and two
partitions, C and D, your DBLSPACE.INI file would include the
• Save the changes you made to the DBLSPACE.INI file and use the
ATTRIB command to reset its attributes as follows:
attrib dblspace.ini +h +s +r
• Restart your computer.
After you restart your computer, DoubleSpace uses the new drive letter
as its host partition. This results in no available drive letters
between your physical hard disk drive and the DoubleSpace host
partition to use for network redirections. You are forced to use drive
letters that follow the host partition drive letter; this prevents the
floppy disk drive icon problem from occurring.
NOTE: This procedure restricts the creation of additional DoubleSpace
compressed drives. If you later decide to create additional compressed
drives, you must change the LastDrive= statement in the DBLSPACE.INI
file to a higher letter than the one specified in ActivateDrive=. For
example, if your host drive is assigned to D, your DBLSPACE.INI file
should include the following lines:
This gives DoubleSpace the necessary drive letter to use when it
creates another DoubleSpace compressed drive.
Microsoft has confirmed this to be a problem in MS-DOS versions 6.0 and
6.2. We are researching this problem and will post new information here as
it becomes available.
