Currently I have MSDOS 4.01 installed with a RLL HD controller on a 386sx. I have two HDs connected; a st277r(65Mb) and a st157r(49Mb). the 65Mb is C: the other is D:. When I boot, Dos only recognizes C: unless I load dmdrvr.sys. Why? Is there any way to get around this? Any help would be appreciated. Thanks Joel Lucsy

Backup everything on that drive. Use Disk Manager (i assume that's where the dmdrvr.sys comes from) to remove the partition. Then use FDISK (on your DOS disks) to set up a new partition on that drive. Then do a FORMAT D:, and restore the files. With Compaq DOS 3.31 or any version of DOS 4.xx you should *always* use DOS to partition the drives.

(Unless you have some obscene drive that is more >than 512 Meg) Don't be crazy. dmdrvr.bin is the device driver for disk manager as you mentioned. It works just fine, and removing it is more trouble than it's worth. The device driver provides SOME protection from SOME hard disk virus software, like stone. It also in any instances (probably not here) provides higher disk I/O rates that w/o it. I too recommend using disk even with dos 3.3, but usually use disk manager to prepare the disk (LLF) before using fdisk and format. And before the (recent) improvements to fdisk & format, used it (disk manager) exclusively. The ONLY problem I had was with OLD versions of diagnostics software like norton or with ill behaved installed TSR's (which I quickly dumped, as they were causing other problems that I hadn't pinned down anyway...). al -- Al.
