Well hats off to you, it worked!
I have now fixed the faulty internals of the two faulty Micropolis hard
drives by teasing out the black gooey mass that use to be the head park
rebound bumper / end stops for each drive.
They had turned into a black sticky mush and as you correctly identified
were holding the heads from un-parking.
However one of the logic board has also gone faulty so if anyone has a spare
faulty drive they would be willing to part with the hopefully working bottom
logic board please contact me.
