I used it with one PC based system with excellent results. However, up
front
I assumed it may be twitchy so I used the best ST225 (minimum surface
defects) I had , shortest cables usable, and didn't format it until it was
warmed up to operating temp and the controller was a WD1005 (memory
test here). I'd never do it with an ST251 as they were flaky in my book
even for MFM. I found the best candidate for this was Quantum D540s
a 30mb MFM drive.
