Thanks to the people on this list and one other
(thanks Matt!) I have got my
RD53 working reliably now. I currently have it installed in a MicroVAX 2000
with 6MB of memory running MicroVMS 4.6 and DECnet.
I had to remove the old bumper which had become sticky. But to make the disk
work I had to replace the bumper, so I used some folded over post-it notes
taped to the top of the head assembly. This seems to work for now, but I
fear a better solution is needed.
You could try a thin bump-on rubber foot, as used on some small
electrical equipment.
I also get a grinding noise which becomes
apparent after the disk has warmed up. I think this comes from the graphite
pad underneath. I plan to loosen the mounting bolts a little more to see if
that gets rid of the noise, but I am wondering if there is any other way to
get rid of it. Why is the graphite pad needed? What would happen if I
removed it?
It's an antistatic measure for the spindle. Try bending it a little.
It's unlikely to do any harm running with it bent right our of the way
for a while, so you can find out if that's what's making the noise.
