WD HHD Problem

[ahmad21]

Last week my 2TB WD Caviar Black HDD gone bad. No and anytype of sound coming out of it. But it shows 0.0gb in my bios. Is this PCB issue. changing pcb or swapping rom resolve this or what?

What do you mean by "no noise"?

Is it spinning up?

[ahmad21]

no its not spinning at all, no noise coming out of it, but it showing 0.0GB in bios.

What are the full model of the drive and PCB? WD..-... and 2060-...

[pcimage]

no its not spinning at all, no noise coming out of it, but it showing 0.0GB in bios.

Then you can try and new PCB with ROM swap.

If it doesn't have an external ROM at U12, then you need pro help

[ahmad21]

Its full model is WD2002FAEX-007BA0
and
its PCB model is 2060-771624-003

Seem like those have ext ROM.
Follow pcimage's suggestion.

You can also check some of the components with a multimeterif you have one and have basic electronics understanding. Use the search function. May be easier to restore. It all depends on damage extent.

I would think that if the drive identifies itself to BIOS, albeit with 0 LBAs, the this would mean that a large part of the PCB is OK.

Could it be that the MCU cannot see the preamp, and would this produce the observed symptoms? If so, perhaps the OP could examine the preamp contacts on the PCB.

i tried new PCB with bios swap but no use. same condition not spinning up and showing 0.0gb in BIOS. any recommendations. I have attached the picture of PCB, there is pointer pointing towards replaced chip. Any more chip that has to be swap.

Clean the HDA contacts.

[ahmad21]

Did you try the donnor pcb with the donnor rom (without rom swap) ? Does it spins that way ?
Insulate the head contact on pcb with a piece of plastic foil. Does it spins that way ? If so pre-amp inside the head stack is most likely shorted.
Do you have any tool like wdr, salvation, etc ?

Yes i tried that way also but no use, same condition not spinning. No I have no tools. But there is a person who have PC3000 only. Actually i am not the professional specially for hdd and also there are no hard drive experts in my country. I live in Pakistan.
