Can't Access Compressed Drives; DBLSPACE.BIN Is Not Loaded (107136)


The information in this article applies to:
    • Microsoft MS-DOS operating system 6.2
    • Microsoft MS-DOS operating system 6.22
This article was previously published under Q107136
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

You may receive the following error message when you start your computer:

You cannot access any DoubleSpace-compressed drives because DBLSPACE.BIN is not loaded.
NOTE: DBLSPACE.BIN is the portion of MS-DOS that provides access to DoubleSpace-compressed drives.

CAUSE

This problem occurs when you have the following line in your CONFIG.SYS file and DBLSPACE.BIN is not in the root directory:

device=c:\dos\dblspace.sys /move

RESOLUTION

If you have DoubleSpace-compressed drives, you should copy DBLSPACE.BIN to the root directory of your boot drive. You can either copy it from the directory containing your MS-DOS files or expand it from your setup disks to C:\.

If you are not using DoubleSpace, remove all references to DBLSPACE.SYS from your CONFIG.SYS file.

MORE INFORMATION

This situation can occur when:
    • You remove MS-DOS 6.2 and Uninstall restores your pre-MS-DOS 6.2 CONFIG.SYS file, which includes the DEVICE command for DBLSPACE.SYS.
    • You format the host drive (to remove DoubleSpace) and then restore your backed up files (including your CONFIG.SYS file with the DBLSPACE.SYS reference).
    • You have one or more DoubleSpace-compressed drives, drive C is not compressed, and you delete DBLSPACE.BIN from the root directory of C.
