That is what fixed it, hair dryer blowing around the unit. I stayed away
from the circuit boards and just kept moving to
different places. I
thought a head was sticking, but it finally started to move a
bit so it
might have been a really gummed bearing. Or #3 head was stuck and
loosened, most of the errors are on that head.
Running it through the MFM tool got all but 200 or so sectors on the
first pass, most errors were on head 3 but tapered off after cyl 500.
Seems like a normal copy of Accent, no special information so it might
not be worth taking the world apart to get it working.
Thanks everyone. Back to

I had suggested a hair-dryer, as recommended circa
20 years ago for drive "stiction" after disuse. It seems that worked.

I have simply opened and physically moved the disk counter clockwise a
turn, in a clean dust-free place.? Or try putting in an oven on warm for 3
minutes a side, all four sides to loosen the grease.? Might sound crazy but
these have worked for me before

20+ years ago, I remember people talking about
disassembling these to fix
the issue.? I?ve never tried.? Though I have one or two that might benefit
from is.? If the CLASSICCMP archives from ?97-2000 are online, I?d
recommend running a search against them.

Ok, so out of the basement came a Micrapolis 1325
(the old Dec RD53
disk) with what appears to be stuck heads. Rotor tries to move
under power
but can only take out slack. Will move backwards a bit.
Is this stuck head, and what would be the best
way to free it? The
reason I'm asking is this disk had a SA1000 adapter mounted
under it so I
am pretty sure it was a PERQ disk. Which means data may be priceless. And
of course it's stuck.
Thoughts?
