PCB replacement... Unable to locate PCB!!!!

[Chrisk]

Hello,

I have three Western Digital WD15EADS. A lighting storm hit and fried my sever and everything in it. I looked at the PCB and the same chip fried on each board.
I found the website hdd-parts.com but they do not carry the board I need. Can anyone help?

HDD 1:
DCM:HHRCNT2MH
PCB number: 2060-701640-001-RevA
HDD 2:
DCM: HHRNHT2MH
PCB number: 2060-701640-001-RevA
HDD 3:
DCM:HHRNHT2MH
PCB number:2060-701640-002- RevA.

If more information is needed please let me know. Thank you for any possible help you can provide.

Here is an image of the PCB chip that burnt. It as the same chip on all 3 boards.

Chip that fried

You are lucky in that your board has an 8-pin serial flash memory IC at location U12. This chip, or its contents, needs to be transferred to your replacement board. Your local TV/AV repair shop should be able to do this for you. Otherwise some PCB suppliers will include a firmware/ROM transfer for US$10-$20, or even for free.

Move the U12 to Donor PCB and ur done
thats all

and plug and pray , nothing else is defected

Hi,

If your data is valuable, I think you should go into a pro, as any other actions could result also in further damage.

If it's not too valuable, you can try to find a donor PCB and swap ROM chip (U12).

Can you give me a suggestion of a place that might have the PCB? The problem I am running into is that no one seems to have this board.

I've found that with newer drives it's harder to get just the PCB, you sometimes need to buy the entire drive as a donor.

I thought you needed to match the numbers up on the PCB board? Or is moving the chip over fixing that issue?

[Nick_CT]

What I meant was that it's hard to find someone who will stock/sell just the PCB of a newer model drive, as these drives haven't been 'retired' yet. ie. you might need to pay for the whole drive, not just the PCB.

Yes, you'll need to match the PCB number as well as swapping the 8-pin U12 chip.

[Chrisk]

That is the other issue I have run into. I have not been able to find a new drive that matches my PCB. I would send the drive to a data center but so far the estimates give me heart issues.

Try PM'ing Eric Lee or networkpc3000, I'm sure either one of them may have it.

I have done so, lets hope they can help!. Thanks again for everyones input. i still welcome more if anyone has anything else.

[Nick_CT]

Eric Lee is a good source, but he doesn't always have stock of the newer stuff. Good luck.

AIUI, the DCM number is important when matching the internal parts, but not when matching the PCB.

BTW, your problem really only requires a simple board swap and chip swap (or reprogramming in situ), not a "data recovery". If the DR centres are gouging you for this trivial service, then look elsewhere. If you take hdd-parts.com as your guide, then you shouldn't need to pay more than $70 per board. In fact you should be able to use the one board for all three drives (with three chip transfers).

HI,
i have this model of PCB in stock. please let me know if need help.

[BlackST]

Here the entire drive is available (new) at about 80-90 EUR average, but have to check for PCB compatibility to be sure. Also, sometimes it is cheaper to buy external enclosures that are known to have the needed drive inside, for "unknown" reasons it can cost less than the bare drive and you have a power supply and an enclosure in bundle !

[harddrivedonor]

Hi, i also have a pcb for you in stock.

Hi

I would place a warning here.
without checking preamps u put your data to risk if u just replace PCB even with ROM transfer

Find some literature here

look and decide. I must add that not all DR firms begin lightning shot drives with checking preamp, so u cannot be sure anyway

pepe

[Chrisk]

Because I have gotten many request for all the board pics. Please see the attached.

While that Post makes sense, is there a guide anywhere to help with checking?
