With that I was able to try formatting an ST-225 with
V2 firmware and V4
firmware. They both worked. I was able to install RT-11 and boot from
the drive (I plan to try rsts next, which is has been my goal for a
while).
So it wasn't firmware - it was operator error :-)
I put the log of formatting with zrqch0 here:

I think my problem is that I got fixated on "autoformatting". This
turned out to be wrong (probably works fine for an drive which already
has an FCT but not for a drive used ina pc).
If I had a big enough MFM drive I'd try BSD but the biggest MFM I have
is 20mb. All my larger drives are ESDI. RSTS should work on a 20mb
drive... he said... crossing his fingers (and remembering it ran on
2x RK05's at long ago... :-)
Cool -- thanks for putting the log up. I'm
fairly sure that's exactly
what I've tried, but I'll have to have another go at it next time I get
a chance.
