You are far from the solution at this point.
You need to do the alignment after select and get the perfect match for donor.

Are you even sure that it's the heads? How did you diagnose?

The most common problems at WD, Bad Sectors, PCB, MHA, SA some times FDB, like jono told u, are u sure its head problem, the knocking its contruisly, or knock 2 times and knock again, then motor stop, knocks 3 times and spindle stop what are getting on ATA registers? does hdd never reach readiness at any time?

Regards

Hi Beto

The 7 knocks are continiusly and THEN STOP .The bios configuration is :WDC ROM MODEL--SHABRE-
so what is your advice.

Thank u

Regards

I think no servo.

1. pcb or contacts
2. preamp
3. head

But similar can be SA problem as well, but on this case the head can read the servo.
