SUMMARY

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.

SYMPTOMS

When you use the DBLSPACE /HOST command to change your DoubleSpace host drive letter, you may receive the following message

The drive letter <X> is not available for DoubleSpace's use.

where <X> is the drive letter you specified.

CAUSE

You receive the previous message when:

  • The letter you specify for the new host drive is in use by an existing physical drive or DoubleSpace drive. -or-


  • The drive letter you specified is greater than the LastDrive= entry in the DBLSPACE.INI file.


RESOLUTION

To determine which drives are currently in use on your system, type dblspace /list at the MS-DOS command prompt, and then press ENTER.

To specify a drive letter greater than the LastDrive= entry in the DBLSPACE.INI file:

  1. Use the DBLSPACE /LASTDRIVE command to increase LastDrive= entry in the DBLSPACE.INI file. For example, type dblspace /lastdrive=j at the MS-DOS command prompt and then press ENTER.
  2. Restart your computer.
  3. Use the DBLSPACE /HOST command to change your DoubleSpace host drive letter. For example, if your DoubleSpace-compressed drive is drive C and you want to change your host drive to drive I, type the following at the MS-DOS command prompt and then press ENTER:

    dblspace c: /host=i:

  4. Restart your computer.
