I have a 1.5 TB Seagate with an initial stuck spindle. Customer does not recall dropping the drive. Switched the platters using Base Replace and imaged 48% using Atola. There were are problem areas at the beginning and ending of the drive and head 4 did not respond at all.

Changed the heads and now the drive just clicks and spins down, where previously it would click but eventually become ready. I tried accessing via terminal, but isolating the motor connection does not get a response. I also could not find any information on this particular PCB's short points. I have not tried the donor heads back in the donor drive yet, but will do that on Monday.

Does anyone know how to short this PCB to get terminal access? The PCB number is 100530699? I can post a picture of the PCB on Monday as well.

Honestly, the best option for image drives is DDI, I gues you may have more chances with all options in DDI to recover the image.

It sounds like bad heads, as you mentioned, and before you make more tests, you need to return the heads to donor drive and confirm they are okey.

I dont see how will help connecting to terminal.

Can anyone confirm that these are the Read channel short points?
