Start with one drive at a time (look at the activity led).

DSKINI will format the disk.

Full commands can be found at:

http://members.tripod.com/coco_docs/id87.htm

With only the 3.5" drive hooked up and a blank DD disk (720K or 1.44 with
density hole taped over) type:

DSKINI

It should format the disk on one side (35 tracks).

If it fails try:

DSKINI 1

If the first fails and the second works then the 3.5" is configured as the
second drive.
