If you uninstall MS-DOS 5.0 or later on a machine that has been partitioned with Ontrack Disk Manager, you should continue to use the Disk Manager drivers supplied with the version of MS-DOS that you were using when you partitioned the disk. If you don't use these drivers, disk corruption can occur under certain circumstances.

NOTE: This does not apply if the Disk Manager drivers are dated after the MS-DOS 5.0 files.


If you upgrade to MS-DOS 5.0 or later and have a partition that is larger than 32 MB, Disk Manager updates the sector information so that it appears acceptable to MS-DOS. However, if you then uninstall MS-DOS to use an MS-DOS version prior to version 5.0 and you use the earlier Disk Manager drivers, the drivers are not MS-DOS version-aware, so they cannot reset the sector information automatically. This could cause disk or file corruption. The Disk Manager drivers supplied with MS-DOS versions 5.0 and later are MS- DOS version-aware.

To avoid these kinds of disk problems, continue using the most current Disk Manager drivers.
