   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...).
