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\" (without the quotation marks) 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:
a. Copy ATTRIB.EXE to the host drive.
b. Copy DEFRAG.EXE to the host drive.
c. Unmount the Stacker-compressed drive.
d. Clear the file attributes on the SVF. For example, type "attrib -r -s -h
stacvol.*" (without the quotation marks) at the MS-DOS command prompt and
then press ENTER.
e. Run DEFRAG /H <host drive> to fully defragment the Stacker host
drive.
