< Well, the negative things folks have said about RD53's are definitely tr
< It would not spinup properly. Seemed to have a speed control problem as

Classic RD53 spin down disease. the problem is the head positioner is
stuck (literally!) to a rubber bumper.

The fix, open the HDA, put power to it and when the platters spin up
and the head lock unlocks give the head a push to the outer edge of the
platter. If it makes noises and does a seek th the outer track your up
and you can put the cover back on. The problem will occur avain when
powered down. Seems there is a rubber bumper in the voice coil positioner
that gets gooey and the head sticks. I have two I've had to remove that
bumper from (not for the timid).

< ?54 RETRY

Of course the boot device is not up so the boot fails.

< The inside of the TK50 is rather dusty and dirty. I plan to take it out
< get as much dust and junk out of it as possible before I put in a tape (
< got the DEC MVII Diagnostic tape, MicroVMS 4.2 and a DECUS tape with a
< bunch of utilities :) ). How critical is it to have a very clean drive?
< Seems the opening on the front of the drive with no tape inserted allow
< too much junk to wander into it.

vacuum it out! FYI: check the fans, that box should have all of them
going(ba23 two on the side, ba123 three on the bottom.).

< Anybody have an RD54 or equivalent they're willing to sell me?

RD54 is a MAXTOR 2190 series that should help as they were used in other
stuff.
