My MVII is not working

< 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). < 2.. <more than a minute wait here> < ?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. Allison
