One  thing I noticed while reading through the MINIX sources is that the
DISKFIX program probably doesn't work right on DOS 3.x hard disks.

The reason for this is that the DOS indicator in the partition record is
assumed to be 1; but in DOS 3.x it is in fact normally 4  (indicating  a
DOS file system with 16 bit FATs).

To fix this, just change the constant at the start of the program (named
DOS_TYPE)  from 1 to 4.  Mind, to do it properly you should define a new
constant, perhaps DOS3_TYPE, and check  for  both.   Assemble  and  link
DISKFIX. Use  FDISK  to  get  rid  of all partitions, then to set up all
wanted MINIX partiitions (these will be marked as DOS ones by  FDISK  at
this  stage). Run  DISKFIX  to convert all DOS partitions to MINIX ones.
Run FDISK to define a DOS partition. Set the DOS partition as the active
one.

Now run FORMAT to soft-format the DOS partition. Off you go!

Hope this helps.
