First thought goes to heads...

It is definitely not able to reach track following. It can't even properly catch servo.

90% chance of heads is my guess....the other 10% is left for strange occurences. heh.

In fact . No servo, no TF, and Gray Err.... Heads, or a bad PCB (the read channel completely KO with everything else OK) or something weird....

This was my guess as well, the other 10% i spoke of includes read channel KO.




I would assume that this drive is clicking, probably want to try the PCB on another drive and see if it clicks in same pattern.

On samsungs it also shouldn't hurt to try a known good PCB on the bad drive, and see if you get the same clicking/terminal output.

He begins by clicking the exit of the terminal, I imagine that is also head, I make the switch and put the result after, thanks to all

Hi
GryDetectErr
H: +00001

means head gone. 95%, 5% PCB

Can you open it and try to see the head 0 at the microscope.

Maybe head is dirty, and can not read the SA.
