I have a problem with a MY Passport USB 3.0 which contains a WD5000BMVW-11AMCSO.
This drive on first appraisal was not spinning up but the PCB was receiving power (led on).
I acquired a replacement PCB from HDDZONE (2060-771737-000) rev P1 and was advised that the serial ROM for the SYMWAVE at U8 and the serial ROM for the firmware at U12 would need swapping.
I tried the replacement PCB just to see if the drive did spin up and this was successful. I then got U8 and U12 chips transfered via a third party , which appears successful, however on return the replceement PCB displays the same symptoms as the original.
Although the the drive does not spin up it is detected as a generic WD mass storage device and displays the following
