This information applies to both Microsoft DoubleSpace and Microsoft
DriveSpace. For MS-DOS 6.22, use DRVSPACE in place of DBLSPACE for
commands and file names.
You receive the following error message if you attempt to create a new
DoubleSpace drive by typing DBLSPACE /COMPRESS on a drive that has
more than 512 megabytes (MB) of data:
Drive C contains too much data to compress. To compress a drive, it
cannot contain more than 512 MB of data.
If you type DBLSPACE under the same conditions, you receive the
following error message:
DoubleSpace did not find any drives that can be compressed. To
compress a disk, first make sure it is formatted and does not
contain over 512 MB of data.
To work around this problem, you can delete unnecessary files so that
you have less than 512 MB of data or follow the procedure outlined
To work around this problem without reducing the volume of data on
your hard drive, manually create a new DoubleSpace drive and move data
to the new compressed drive. Once the uncompressed drive contains less
than 512 MB of data, you can then compress that drive.
To manually create a new DoubleSpace drive:
• Copy the DBLSPACE.BIN file from the DOS directory to the root
directory. For example, if the DOS directory is on drive C, type the
following at the MS-DOS command prompt and then press ENTER:
copy c:\dos\dblspace.bin c:\
• Set the file attributes on DBLSPACE.BIN to read-only, hidden, and
system. To do this, use the ATTRIB command as in the following
attrib c:\dblspace.bin +r +s +h
• Create a DBLSPACE.INI file using the COPY CON command. To do this,
type the following at the MS-DOS command prompt and then press
• Press ENTER twice.
• Press CTRL+Z and then press ENTER to close and save the file.
• Restart your computer by pressing CTRL+ALT+DEL.
• Run DoubleSpace by typing DBLSPACE at the MS-DOS command prompt
and pressing ENTER.
• From the Tools menu, choose Options.
• Increase the "Last drive reserved for DoubleSpace's use:" setting
five letters. For example, if the current letter for Last Drive
Reserved For DoubleSpace's Use is D, increase that setting to I.
• Press ENTER to save your changes and then press ENTER when you are
prompted to "Restart Your Computer Now."
After the computer has restarted, you should have a complete
• You can now run DoubleSpace and create a new compressed drive. To
do this, type DBLSPACE at the MS-DOS command prompt, press ENTER,
and then choose Create New Drive from the Compress menu.
After you create the new DoubleSpace drive, you can move data from
your uncompressed drive to your new drive. If you reduce the data on
the uncompressed drive to less than 512 MB, you can run DoubleSpace to
compress that drive.
NOTE: If you move Microsoft Windows or Windows-based applications to
the new drive, adjust your .INI files and run Registration Editor to
reflect the new drive location of your files. If you move system files
or network files to the compressed drive, adjust your CONFIG.SYS and
AUTOEXEC.BAT file accordingly.
