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.

Neither the graphical interface of the full-screen DoubleSpace maintenance program, nor the DBLSPACE.EXE command-line switches allows you to reserve zero (0) bytes of free space on the host drive during the compression of a RAM drive.

WORKAROUND

To reserve zero bytes of free space on the host drive when you are compressing a RAM drive, use the following procedure:

  1. Create a new drive or compress an existing drive on the RAM drive using either the full-screen DoubleSpace maintenance program or the MS-DOS command line. For example, at an MS-DOS command prompt, you might type:

    dblspace /create <d>: /size=1.37

    where drive <d> is a 2-megabyte (MB) RAM drive. (This uses 1.37 MB of drive D to create a compressed RAM drive and leaves approximately 0.62 MB free on the drive D.
  2. Resize the compressed drive to its maximum size and the host drive to zero with a command similar to the following:

          dblspace /size /reserve=0 <h>:
                            

    where <h> is the drive letter of the compressed RAM drive. To determine the drive letter for the compressed drive, type dblspace /list at the MS-DOS command prompt.


MORE INFORMATION

Reserving 0.0 MB on the host drive of the RAM drive ensures that no RAM is leftover as unused space on the host drive. The above procedure does not apply to the compression of a hard disk drive.
