I have found my old ST251-1 HD from my parents loft and even though I should have all the data off it when i moved to another computer I would still like to check a do a proper copy of everything from it if i can.
Problem is when power is applied (nothing else connected) it spins up fine but doesn't do the head seek/calibration bit and so is stuck in its parked area.
I have moved the heads out manually and powered down, the stepper motor correctly auto parks the heads.
I have replaced the 2 power capacitors on the main control board as mentioned here :

to no avail, the logic would suggest get another ST251-1 off fleabay and swap the control board, as with anything retro now the prices are ridiculous, so would anyone have any ideas why the drive won't calibrate/seek after spinup and/or things to try?
This is exactly what it sounds like (link starts at 1:09) :
Spins then a small strain sound then nowt (except spin). Drive therefore doesn't initialise.
Any ideas what could be wrong?
many thanks
