WD5000AAKX-60U6AA0 Click twice then spins down

[gameboybin]

I got a drive 500GB WD. That from the beginning was clicking twice then spins down. Upon inspection the PCB, the ROM everything seems fine. So i came to conclusions that it is the heads

Got a matching donor, checked the platters and swapped heads. The drive still Clicked twice then spins down
I have tried uploading LDR, tried hot swapping but nothing worked.
Can anyone help me out?? Any suggestions is welcomed??

Thanks everyone!

Did you try head mapping? may be 0 or 1 ,any platter damaged?

yes. i've tried head mapping still double clicks and spins down. I checked the platters. No visual damage.

likely heads are gone...

i checked the heads. they are perfectly fine. swapped them back to donor. still works

[MindMergepk]

did u rule out PCB, did you test patient heads in donor ?

I did rule out the PCB, but i haven't tested patient heads in donor
