The only thing I can think of is a shareware program called HDSENTRY.  What it
does is disable the interrupt for all writes to the hard drive.  It beeps and
prints a message everytime a write to a hard drive is attempted.  Only way out
of HDSENTRY is to reboot.  This works fine from DOS.  I don't know if the
program is available anymore.  Check simtel20.arpa to see if they still have
it in their archives.  Only other option is to write your own program that
will disable DOS writes to a hard drive.
