22 Medalist 17240, 13030, 10231, 8420 and 4310, Rev. B

Supported operating systems

The Disk Manager dynamic drive overlay provides support for drives that have capacities greater than 528 Mbytes under MS- DOS, Windows 3.x, Windows 95, Windows NT 3.51, Windows NT 3.50 (requires DM upgrade drivers), OS/2 V3.0 (Warp full pack), and OS/2 V2.0–3.0 (requires DM upgrade drivers).

Before you install a non-DOS operating system on the drive, install DOS and Disk Manager and make sure that the drive is bootable. Instructions for running the dynamic drive overlay with other operating systems are available in the Disk Manager online manual.

Removing the dynamic drive overlay

If Disk Manager installs a dynamic drive overlay (DDO) and you do not need this software to access the full capacity of your drive, you can remove the dynamic drive overlay without losing your data. However, you will lose access to the full capacity of your drive unless you have another method for accessing high- capacity drives (see Addressing drive-capacity limitations on page 11).

Caution. Before you attempt to remove a DDO, make ! a backup copy of all the data on your hard drive. Also, run CHKDSK, SCANDISK or a third-party equivalent to detect and repair any damaged files before you follow the procedure below. If the DDO migration program encounters a serious file problem or is interrupted by a power loss or hardware failure, the migration will fail

and your data will be lost.
