Hmm... those aren't so
common (in the DEC world, there are two
choices - the RD53 (Miniscribe 1325) and the RD54 (Maxtor XT2190).
Jerome Fine replies:
By the way, the RD53 is a Micropolis 1325 or 1335 with the
R7 jumper added to the logic board. Otherwise, the DEC
RQDX2 will not recognize the drive. I have never tried them
on the RQDX3 without the R7 jumper, but it might be possible -
probably NOT.
And while there may still be rare occasions when you can actually
complete the FORMAT required for an RD53, I would recommend
that they be used ONLY for scratch at this point at the end of their
life cycle. I suppose that there might still be the odd RD53 that is
still living a good life, but most (almost all) have become so unreliable
that I strongly recommend NOT using them for any files you care to
see the next time you turn the computer on.
Sincerely yours,
