Let me recommend HDT or Harddisk ToolKit. a very nice
formatter/partitioner on classic mac OSes like system 7 and around.

  Hi!
 I installed A/UX on three different Quadras, with various HD (one was

 The disks weren't Apple original, so a patched partitioner was needed.

 If you need something, contact me in PM. 
 Thanks!
 It does look a little daunting, but it should be interesting, at least...
