Wow. I didn't know that anybody besides Commodore ever used XT IDE. I have
a couple of WD-98???-X drives, one in a Commodore Colt that I use for ROM
burning. IIRC, WD made 20Mb and 40Mb XT IDE before moving on to AT IDE.
Commodore even designed-in an XT-IDE port on their A2091 and A590 disk
controllers for the A2000 and A500, respectively. The A590 did ship with
20Mb XT drives; the A2091 did not have the 40 pin connector soldered in place.
It does work; I have retrofitted one. They are slow.

And, yes, the ST251/251-1 are both MFM. I use them on ancient DEC hardware.
