Western Digital WD800AAJS 80 gb SATA drive PCB swap

[y2kcio]

Hi all,

Does anyone know if I can just switch out the PCB with the exact same part number on this WD800AAJS 80 gb SATA drive?
Or does it contain unique bad sector information on the PCB?

The drive powers up to full speed, no clicking noise and the drive is not detectable by any computer whether hooked up
directly to a SATA controller or hooked up using an external USB to SATA dock.

Any help would be appreciated!

The PCB does not store and 'bad sector information', the P-list and G-list is stored on the drive (platter) itself. PCB would house adaptive info and microcode that allows the drive to initialise, so this needs to be moved when a replacement PCB is used.

It does not sound like the PCB is your problem though.

I've been told as long as the PCB doesn't contain the P and G lists, I can try and swap out the PCB with a replacement board and see if it works. I was figuring it was the PCB since the drive won't detect even though the platters spin up.

You've been told by 2 people who do this everyday that it's very unlikely that the PCB is your problem. It's probably not what you want to hear, but the problem is very likely elsewhere and you will be wasting your time swapping the PCB.

Best to contact a recovery company if you want the data recovered, we can recommend many in your country if you want to go this route.

The PCB myth is too hard to die...
