DriveSpace Err Msg After Installing over PC-DOS 6.1 or 6.3 (122120)
The information in this article applies to:
• Microsoft MS-DOS operating system 6.22
This article was previously published under Q122120
When you try to run the DriveSpace utility from MS-DOS 6.22 after upgrading
from PC-DOS version 6.1 or 6.3, the following error message is displayed:
This error occurs because the compression driver that IBM ships with
versions 6.1 and 6.3 of PC-DOS is incompatible with DriveSpace.
MS-DOS 6.22 Setup runs correctly because the compression is not on the boot
drive. Setup completes with no data loss; however, if you then try to run
DriveSpace to convert the compressed drive, the above error message occurs.
You must copy the original PC-DOS DoubleSpace files back to the host drive,
back up the data, reformat the host drive to remove compression, and then
restore the data.
The README.TXT from MS-DOS version 6.22, section 1.17 recommends that
PC-DOS users remove disk compression before upgrading.
