I haven't, although I do own two STs. I suggest you head over to join the community over at
www.atari-forum.com
There are a lot of very technically minded Atari ST specialists in that forum.
You don't say whether the drives are 360K single sided as per original Atari ST, 720K double sided as per later Atari ST, or 1.4MB.
Most STs only natively support the first two, although it's possible that later versions of TOS (2.xx?) may have native support for 1.4MB drives. As I said, the above forum is the best place to pose your question.
