WD3200AAKS Dead

[markmarques]

Hi,
I have a WD3200AAKS-00AYV0 HDD that is dead ... ( dead with no apparent motive whatsoever )
( No noise, not detected in BIOs ) ...
With such symptoms what can I expect to be damaged? the plates ? motor ? or PCB ?

I know the DIY solution can do more harm than good most of the times but I have to ask and before doing any damage to the HDD and trying to do a DIY recover ...

can I swap the PCB from another HDD with the same WD3200AAKS ( but different model ) ?
Or do I have to match exactly the same full model ?


I have several WD3200AAKS models ( still working ) with different models can I put a different PCB model
and start the hDDwhat could be the damage to the existing data in the plates ?

THanks in advance

No sound from HDD at all ? Even when you put your ear close to the drive ?
For PCB replacement you need to match the PCB no. I.e. 771640, and need to swap the ROM chip too

As stated in the post "no noise" whatsoever ...
The HDD were directly connected to SATA board and supplied from the main power supply.
Thought that the power supply had some kind of problem, so I swapped to an External USB enclosure with the same result...
( no noise , no action, nothing ...) ...
It is acting like it has no power , the BIOS does not report anything ...

I had several HDDs that died but had some kind of warning ( strange sounds and SMART warnings )...
This is the first time that the system disappeared ( become dead ) without any warning ...

Might be a power surge ?!

The computer case has several HDDs but only this one failed ...
This is really the first time that I had an WD HDD failed without any warning ( noise, SMART BIOS warnings , etc) ....

The data inside is not that important ... but if I could recover it ...

Nonetheless I am trying to learn new DIY details ...

I know enough not to open the HSA case but if I can solve the issues via swapping a PCB or something similar ....

Thanks for the information

After ordering and receiving an exact PCB replacement
WD3200AAKS-00VYA0 model,
I swapped the PCBs and the HDD started to spin up....

Although the computer BIOS did detect "something" it does not give the correct size ( 0 Gb ) ...
It does not give and inidication of the "WD32xxxx" initial string nor any serial ...

Was it supposed to happen like this ?
What is the next step in order to "revitalize" the HDD ?

Do I need a TTL cable ?

You need to swap the ROM (U12 Chip) on your old PCB to the new one. Post a photo of your PCB and we can help you identify the right chip that you need to swap.

TTL cable won't work with Western Digital because it doesn't use terminal.

AS requested here is the "bad" PCB photo ...
Apparently there is no visible damage so what could be wrong ?

Bad PCB

ROM on this PCB is embended
measure diodes and 0 ohm resistor

[markmarques]

It seems that the "D3" and "D4" diodes have different from 0.0 Ohm values ...

Were all of them supposed to have 0.0 Ohm ?

Any ideas are appreciated ...

Easiest way is to select continuity mode on your MM, one that "beeps" on continuity.

R64 and R67 should beep, D3 and D4 should NOT beep.
