Are you sure the 3.5" HD isn't f03ht ?

Here is the chart for AT&T UNIX V/386 3.2.2.  I would expect ISC to
be similar:

      Diskette Type             Device         
      -----------------------------------------------
      5.25" 1.2MB DSHD         /dev/[r]dsk/f_q15dt
                          -or- /dev/[r]dsk/f_5ht
      5.25" 360KB DSDD         /dev/[r]dsk/f_d9dt
      5.25" AT&T UNIX PC       /dev/[r]dsk/f_d8dt
      5.25" AT&T 3B2 720KB     /dev/[r]dsk/f_5qdt
      3.5" 1.44MB DSHD         /dev/[r]dsk/f_3ht
      3.5" 720KB DSHD          /dev/[r]dsk/f_3dt
