None of the above ;-)
mount -s -b -f //./drive /dev/drive
where the first 'drive' would be "physicaldrive0", etc. For a floppy or CD, 'drive' would be the drive letter (including the colon). Don't use disk drive letters since
they will give you the partition corresponding to the letter rather than the whole disk. Also, the number in "physicaldrive#" corresponds to the number in "disk#" as seen
in 'Disk Administrator'.
The second 'drive' is replaced with some name you pick. So a real example for Disk0 would be:
mount -s -b -f //./physicaldrive0 /dev/hd00
