Cannot Manually Mount Fragmented DoubleSpace-Compressed Drive (103535)



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 Q103535
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

If DoubleSpace cannot mount a compressed volume file (CVF) at startup because the CVF is too fragmented, DoubleSpace increases the MaxFileFragments setting in the DBLSPACE.INI file and restarts your computer.

However, when you try to manually mount a DoubleSpace-compressed drive (from the command line or using the DoubleSpace maintenance program), DoubleSpace does not mount the CVF if it is too fragmented.

RESOLUTION

To work around this situation, use the DBLSPACE /MAXFILEFRAGMENTS command to increase the MaxFileFragments setting in your DBLSPACE.INI file. To do this:
  1. Use the TYPE command to view the current DBLSPACE.INI settings. For example:

    type h:\dblspace.ini

    NOTE: The DBLSPACE.INI file is hidden in the root directory of the host drive. To find the host drive for your DoubleSpace-compressed drive, type dblspace /list at the MS-DOS command prompt and then press ENTER.
  2. Increase the MaxFileFragments setting by at least 1000. For example, if the current setting is 1000, type the following at the MS-DOS command prompt, and then press ENTER:

    dblspace /maxfilefragments=2000

  3. Press CTRL+ALT+DEL to restart your computer.
