The information in this article applies to:
- Microsoft MS-DOS operating system versions 6.0, 6.2, 6.22
-------------------------------------------------------------------------------
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 " (without the quotation marks)
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" (without the
quotation marks) 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.
