If it spins up then back down and repeats thats a
stuck head
positioner.
When the drive is powered down there is a magnetic retract and at the
end of travel there are bumpers that betwen heat and time get sticky.
The windup then down is the failure of the heads to move and find servo
and it fails.
Just checked, that is exactly what is happening, but it only did cycled two
(or was it three?) times. I will try opening it up to see if it is the
sticky bumpers problem. Has anyone documented the procedure in detail at
all?
