I have about a dozen or so 1325,1335, and 1355 drives here, also some
earlier ones (some have the DEC label) RD50, 51,52, and even a few 54s. If
anyone is interested, please contact me off list.
Thanks, Paul

That is what fixed it, hair dryer blowing around the unit. I stayed away

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
