Noisy ST 251 HD

Well, I guess I had a more practical solution than some that
this thread provoked! Let's try another tact:

I am really glad to find I can use the ST-251 in my DEC
Pro 380 instead of the Quantum Q540, since the later drive
is rarer, older, and perhaps (in my experience) not too
reliable. And has a smaller capacity, of course, and is
a full-height drive.

But now I have just one working 251 plus the one that sounds like
a helicopter taking off, and another one that seems to work but
that has ? ? ? written all over it. I can try to dig up some
more 251s, but I got some remarks saying it wasn't too reliable
a drive, either.

Is there a better drive (MFM) with equivalent geometry?
(820 cyls, 6 hds, 17 sec) or maybe with 6+ heads and 820+
cylinders (that might work, too?). Half-height would be
nice, like the 251, because if I ever get another HD
controller card, I can put two drives in my Pro 380 (only
one drive per controller card, and supposedly only one
per Pro chassis, but the 251 probably uses a lot less
power than the Q540, so two drives should be OK).

Thanks,
Dave
