Supported operating systems
The Disk Manager dynamic drive overlay provides support for
drives with 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
You can remove the dynamic drive overlay (DDO) from your
drive without losing your data. However, if you do not have
another method for accessing high-capacity drives, you will lose
access to the full capacity of your drive (see “Addressing drive-
capacity limitations” on page 10).
Caution.
Before you remove a DDO from a drive, 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. If the DDO migration pro-
gram 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.
