HDD GURU FORUMS

Hello guys I am new to this forum!

I guess I was lead here as most of us, from the need to recover my data from a faulty hard drive.

First of all thank you all who contribute to providing this gem of a knowledge base, after endless crawling online it seems I have finally found, the mecca of gurus!

My hard drive failed is a

Western Digital:
WD Caviar SE16
Model: WD5000AAKS - 00YGA0
DATE: 01 DEC 2007
DCM: HARNNT2CHB
PCB#: 2061-701444-700 AD

I am looking to replace the PCB, and I hope that someone with the right knowledge / resources can set me to the right direction!

Thank you in advance!

This PCB contains unique adaptive info in a masked ROM (inside main MCU) so you cannot simply change the PCB.

Adaptive data needs to be reconstructed from service data on the platters using special tools, you cannot do it yourself.

You need to send your drive to a pro to have this done, or as I understand some PCB suppliers will do this for you for a small fee.

thank you for your reply!
actually i know someone who specializes on PCB soldering so if that is the case i could have them transfer the ROM for me...

as a refference, i came accross this post on HDDGURU:(successful recovery with board swap)
wd4000aaks-00yga0-pcb-replacement-compatibility-t22696.html

a post that you commented aswell pcimage.

i am in the proccess of purchasing a PCB with almost identical DCM.

DCM: HARNNT2CH

1- Motor (H)
2- Base (A) ---------------The one i found is different!
3- Latch (R)
4- Bottom VCM (N)
5- Media (N)
6- Headstack (T)
7- Actuator-Preamp (2)
8- Top VCM (C)
9- Separator (H)

I am hoping to be able to access my data once more like HDDGURU user mooglover:

Hey guys, I've changed the PCB and it worked. I read all the data and copied it to the other hard drive.
It worked besides it has a slightly different PCB board.

My symptoms:
[*]ATX power supply failure
[*]Drive spins up during POST check(BIOS), clicking sound, then spins down - result: BIOS cannot read it

NOTE: recently(before total failure) pc boot was delayed on load when trying to identify / access the hard drive, sometimes BIOS would not even report it, but once in windows the hard drive was fully operational! - this, along with the failed ATX power supply has me hoping that its the PCB thats fried!

please help me troubleshoot and identify gurus!

OP has contacted us and has received a full detailed reply, as to why the problem is not with the PCB.

We have this pcb for sale. contact for more details.
