I have 3 prodrives now that exhibit the spin up, and spin down without any head actuation.

I noticed on all 3 drives when paying close attention, What appears to be tantalum capacitors near teh power jack are actually aluminum electrolytics, and Guess what... They are leaking. everywhere.

So, I know the drives work if you give the actuator head arm a little push on the platter, but they wont do it under its own power.

I may have just found out why.....
