Dear sir:
thanks for your reply .
We Checked everything with MRT machin,it doesn't seem a matter of firmware or something like this.
with a similar PCB head does not click,but stop after some moment.
thanks for your care.

Heads are gone, need to change in cleanroom.
NOT a pcb problem.

It is convenient that when you put the case of the exact model of HDD. Also if you have the MRT you can put a screenshot when the MRT detects the HDD.

It seems that it is a problem of heads as the comrades say, but the more information more details you can help diagnose the case.

Greetings.
