hello,

i have the following hard drive:
WD500BEVT-00A03T0
WWN:50014EE202BC2D97
from the 27 4 2009
DCM: EHCVJBBB
LBA: 976773168
R/N 701609

PCB:
2060-701609-000 REV P1 (on board)
2061-701609-800 03P (on sticker)

the drive is completely dead and i would like to see if the PCB is the culprit.
i have another drive of the same model albeit from 2011.
i tried the PCB from this one and the drive spins (with some clicking however) up but is not recognized by the computer

now what can i do?
i found a similar drive on ebay with a different WWN (50014EE2AD9792EE) and a different DCM (HHCVJBBB)
but with the same R/N and MDL
do i have a chance that i can use this PCB?

what else can i try before i send the drive to a (costly) recovery center?

thanks for all help!

You should send it....

This drive have unique adaptives inside the PCB, you can't use another drive's pcb on this model.

Is there an 8-pin chip at location U12?

no,
U12 is empty

thanks

Then the adaptive information is stored in the main controller chip, and needs to be transferred with professional equipment.

is this an expensive procedure?

Could you upload a detailed photo or scan of the component side of the board? If you're lucky, there may be a simple DIY fix.

shure, here it is

I can't see any obvious problems.

If you have a digital multimeter (US$10), then we could measure a few voltages. We could start with your good board and establish some test points. It may only turn out to be a post mortem exercise, but it may help others.

i do have a multimeter. shoot!

Could you measure the voltages at each of the following test points and components on your spare board?

Also measure the voltages at the jumper pins.

Use the SATA power ground as your reference:

Set your meter on the 10VDC range. Be careful not to slip with your probes, as serious damage will result.

hmm, i just realized you want me to measure my good board.
however, since it seems impossible to simply excahnge the boards, i did not get a good one ...

Well, do the same with your bad board.

what are the voltages supposed to be

hi blofeld i have send a pm to u check please for solution

Hi Blofeld,

I strongly recommend against experimenting on the board hoping to fix it. If your data is important, you really should have a professional rebuild a circuit board for you. You'll need a PC-3000 to do it, which costs ~$10,000 USD. If you mess the board up too bad while experimenting, it may actually become impossible to recover the data.

I normally charge $500~$650 (plus parts) for this type of recovery in my lab based in Providence, RI USA, but if you just want a rebuilt board and not the imaging onto a new drive, etc. I can probably do it for $350 plus parts. Other labs should have similar prices. If you're outside the USA and would like a recommendation of a company to use, let me know.

Yep, that's the problem with donor drive suppliers. They buy pc-3000 just to do a million rom transfers. But, most people aren't willing to risk trying to recover data themselves. So they still hire a professional.

@data-medics, you don't need PC$10K to do a ROM transfer.

To Spildit, as much as I like you, and as much as I am grateful to you, you must understand that the world doesn't owe anyone a living. My mission is the same today as it was 20 years ago when I first started posting to Internet forums, and that is to help people as much as I possibly can. If that conflicts with other people's commercial interests, then that is a fact of life that they will have to accept. When I went into business, I did so with the same understanding, and I still managed to earn a respectable living.
