MS-DOS 6.2 Stacker Conversion Err Msg: Out of Memory (107602)


The information in this article applies to:

  • Microsoft MS-DOS operating system
This article was previously published under Q107602

SYMPTOMS

After you start the Stacker conversion process and DoubleSpace reboots your computer, you may receive the following error message:
AN ERROR OCCURRED while attempting to convert Stacker volume c:\stacvol.dsk to DoubleSpace format. There is not enough conventional memory.

CAUSE

This problem occurs when DoubleSpace reboots your computer and there is insufficient memory to convert your Stacker volume file (SVF) to a DoubleSpace compressed volume file (CVF) due to the size of your SVF.

RESOLUTION

You can work around this problem by using the following procedure:

NOTE: Reboot your computer and try to run the Stacker conversion routine after each step.

  1. Place DBLSPACE.SYS in a parallel directory on the host drive. For example, if C:\DOS contains your MS-DOS files, and your host drive is D, type xcopy c:\dos\dblspace.sys d:\dos\ at the MS-DOS command prompt and then press ENTER.
  2. Edit the CONFIG.SYS file and ensure the DEVICE commands for HIMEM.SYS and, if present, EMM386.EXE are placed before the first DEVICE=C:\DOS\DBLSPACE.SYS line.
  3. Edit the CONFIG.SYS and AUTOEXEC.BAT files and remark out unneeded device drivers and terminate-and-stay-resident (TSR) programs using the REM command.
  4. Defragment the host drive for the Stacker-compressed drive. To do this:

    1. Copy ATTRIB.EXE to the host drive.
    2. Copy DEFRAG.EXE to the host drive.
    3. Unmount the Stacker-compressed drive.
    4. Clear the file attributes on the SVF. For example, type attrib -r -s -h stacvol.* at the MS-DOS command prompt and then press ENTER.
    5. Run DEFRAG /H <host drive> to fully defragment the Stacker host drive.
