WD1600AAJB H.D.D NOT DETECTING IN BIOS

[soren60]

Hello.
My WD1600AAJB suddenly fail.
Disk spin up, but not detecting by BIOS. No noise or visual damage on PCB.

I bought a new similar disk and swap PCB. No luck.
I looking for the U12 chip, but can not see it.

Patient disk:
WD1600AAJB-00J3A0
Date: 02 apr 2009
DCM: DGRNHTJAGN
PCB: 2060-701596-001 REV P1

Donner disk:
WD1600AAJB-56R1A0
Date: 16 feb 2010
DCM: HHRNNT2AHN
PCB: 2060-701596-001 REV P1

On Ebay it is an other PCB for sale, is this a better choise?

DCM: HGRNHTJAHN
2060-701596-001 rev P1 on the PCB

So, what to do?

Picture on patient PCB.

This board does not have an external flash chip. It has a masked ROM within the CPU- the large chip on the board marked with an M. If the PCB is the problem- which it may not be- you will need a professional to copy the contents of the ROM from the patient to the donor. Although you would- like everyone else on this forum -like to do this yourself, I'm afraid unless you invest substantial money in the necessary professional tools this is not possible. Moreover, the PCB is not necessarily the cause of the problem so you'd still need to find a professional DR service if your data is critical.

If the PCB is OK, why does it not shown up in BIOS?

[drc]

Because something else is wrong with it

[msurgeon]

There are many reasons other than PCB failure that a drive will not show in BIOS. Among them are: head(s) failure, firmware damage, platter surface damage, or any combination of these. In fact, PCB failure is usually the cause - in our experience- about 10% of the time.

Ok. Thanks.
How do we detect the failing part?

I'm afraid that you can't. This can only be diagnosed properly by a data recovery professional. Many companies and individuals advertise themselves as "professionals" but have no idea what they're doing when it comes to physically damaged drives. Research companies in your area who do DR and see if you can get some good referrals. It's easy to screw up these drives permanently in the wrong hands. I don't recall any pros on this forum from Sweden but you can check.

[lcoughey]

Diagnosis is easy. Send to a data recovery professional who provides a free assessment. You will find out the problem and the cost to recover the data.

Ok.
But if problem is located to PCB, what can I do? Swap the M-chip?

They offer a ROM transfer service for $10. I don't know whether that covers your model, though.

since there is no ROM, neither place for it on that pcb, the drive will need professional attention.
it is not about swapping ICs. If u would like to see your data again I suggest stopping DIY attempts before it will be late.

I have no idea as to the professional standing of http://www.onepcbsolution.com/.

However, when a vendor offers a ROM transfer service, this does not necessarily imply that the service is restricted to physical chip transfers.

[jono-ats]

It's probably a firmware problem - e.g. module 11 is corrupted. If so, there is nothing you can do yourself.

Now I did a test with MHDD 4.6floppy.
MHDD did not recognize disk.

I did two different tests.

Test1:
Boot computer with electric power off/on.
Disk spin up, and MHDD highlight BUSY, after 10sec disk stopped an highlight ERR.

Test2:
Boot computer soft.
Disk spin up, and MHDD highlight DRSC and DRDY, disk do not stop.

without proper PCB your test nothing meaning. i can help you transfer ROM data into good PCB. please contact me by email or MSN if interesting. swap the MCU chip is the way. but do you think you will get success on swap it? ******think over and over before action*******

[mr_spokk]

Hi, if you value your info on your harddrive don't play around with it to much...otherwise you can lose it all!
A failing drive is not going to be better by trying accessing it with the wrong tools all the time!

Ok, you are sure that PCB is the problem?
When you transfer ROM data into good PCB, do you "flash" the new MCU, or do you swap MCU physical?
And yes I am intressting of your help, if it is for a resonably price.

Where do you live networkpc3000?

Depending on your soldering skill and on the MCU condition.

[networkpc3000]

i always "flash" original FW into new MCU(good PCB), instand of swap MCU physical. it more easy and safe to do it.
