request PCB 2060-771824-003 REV A

I’ve a problem with my WD30EZRX HDD, my pc doesn’t detect the disk any more. I’ve tried many rescue programmes but not one detects my hard drive. The hard drive is running without any suspicious noises, so I guess the PCB is not working. What do you suggest? The PCB no. is 2060-771824-003 REV A, and a second question if I replace the PCB do I have to replace the Bios as well?

Replacement the PCB will not solve the problem below.

    * The drive will power up normally (no ticking noises, errors etc) but will not be recognized by the computer

    * The drive will power up normally and be recognized correctly but will report a size of 0 bytes

    * The drive will power up but report SMART errors on boot

Those problem is caused by the HDD firmware corrupted.You can find a data recovery company help.
