Hi

I also have the misfortune of a crashed hard disk, in fact 2 harddisks!

The cause: a faulty PSU!

I smelled the burning PCB of the Harddisk and new this was very bad.

SO I am looking for a replacement for the board for a WD10EADS (28/12/2009 ) and a STM325031as but also i have some questions.

After reading in your forum its not just a question of replacing the PCB with a new one?
There are unique codes in the circuit logic linked to the software on the disks?

I appreciate your advice in how to retrieve my data

Dobre is in Belgium I would send him a PM. Just have the drives looked at by him and see what he can recommands on this one. WD drive is not such an easy one to work on as it is and if the PCB is actually bad there could (I am not saying there is) be other damage on the inside of this drive.

Other wise post here the specs from the label of both drives plus the specs on the two PCB boards. Make sure you give the number that is printed on the PCB board for WD. This one is important. The other you can get from the stickers on the PCB board. There are people here that sell parts and will contact you on this one.

Last option you can follow Frank on this one. I am sure he will post here soon. Be sure to read the posts here on the forum and especially the one from the guy in Greece who tried to do this work himself and see what happened to him. Good luck on this one

for WD10EADS you had to do FW transfer from bad PCB to good PCB with special tools.
for STM325031as you had to soldering ROM chip from bad PCB to good PCB by yourself or get someones help.

Plus ,
They Are Already Fried ,So In The WD10EADS Its even More Harder .

If you upload detailed photos of both boards, one of us will help you identify the faulty components.

The usual fault is a shorted diode which can simply be removed, in which case the repair will cost you nothing.

Good luck.

Search this forum and the forums at Seagate and WD for "TVS diode".

Sir ,
Lets Make a Small tutorial On this And Post It In HDD Guru .What All Makes Of TVS Have You Come Across .

OK here are the hdd

The SEAGATE HDD has a sticker with number
100471144 E k843E4MB

His pic of the PCB, please note that the component that is defect (diode?) is completely gone!



The Western digital has a sticker with number

2061-701640-202 03PD3 XT 8R22 L2PP 6 0005230

His PIC of the PCB:

Here the smooth chip seems to have the damage:

sir ,
Kindly Read whats Written On top of 8 Pin IC Of All Two PCb And Report back .

[powerbits]

on the seagate hdd i see 2 8 pins chips:

ic1 ON seagate
ATMEL810
25FS12AN
SH27

ic2 on seagate
hjaj
fd8
2p102a


on the wd i have one 8pins ic:

ss7 25l-f02oa

Hi ,
IC Number One Should be desoldered and go to new pcb ,Not Sure Of WDC ,But i think it should Too [ It Seems a Serial Flash Ic ]

IF the preamps still work...

The Maxtor/Seagate board has sustained a hit on the +5V supply.

This is what the board should look like:
http://ep.yimg.com/ca/I/yhst-4446369223 ... 12_1071555

If you would like to attempt a DIY repair, then remove the smaller of the two diodes (the one to the left of the KVP part). This is the 5V TVS diode. Then replace the damaged inductors (?) with wire links.

Otherwise a replacement PCB is available here:

The above vendor offers a ROM transfer service for $10.

The serial EEPROM chip on your WD board is this one:

Do not be unnerved by the attempts to intimidate you into engaging a professional service unless it's really necessary. Remember, you are most vulnerable when you've lost something precious. In that respect data recovery is a bit like the funeral industry, except that they offer to resurrect your loved one .

BTW, if your DIY attempts fail, don't post back. You'll be the butt of merciless ridicule, even if your workmanship is perfect. The DR people will attempt to place the blame on you or me, and then attempt to profit from your failure by intimidating others. I can show you one example where a DR company quoted $1400 to recover data from a drive with a shorted diode. Instead, the owner opted for a simple DIY repair which cost him nothing.

ok guys but about the seagate board

Wat do i replace exactly with wich components.. i have some older HDD where i would pick of the good component
