HELP: WD2500AAJS-40VWA1

[Harddrivenoob]

First off please excuse me if I am not putting enough detail. I have a 250GB Western Digital WD2500AAJS-40VWA1. PCB 2061-701444-600 is on the sticker. 2060-701444-004 Rev A is on the board. It's DCM is HHRNHTJMHN. I am trying to find a PCB that will work with this specific DCM? I am not even sure if that is the correct terminology or if that is something that can be done. But I am looking for help and everybody here seems very knowledgeable.

Thanks in advance

Those have unique info built into the BGA chip... short version: it's not gonna work

[Harddrivenoob]

I guess I should also say that one of the onboard chips has a burn in it which after some research is common with WD drives. Is there any way to move the ROM chips if I have a good PCB?

Unless you have a BGA rework station, no.

[Harddrivenoob]

Are there any folks here from the Massachusetts area that might be able to do this? Any help is appreciated. Thank You.

This pcb doesnt have a BGA chip it has a normal CPU but with alot of pins , most of the times CPU burns it would be helpful if you post the pic of your pcb .

Many AAJS still use non-BGA MCU, and also have U12 present. I was playing with 1600AAJS-00L7A0 today and it definitely has a U12 EEPROM

I never saw this model with an external ROM ?

agree. at last i have lots of 2060-701444-004 Rev A no one have ROM chip.


@Harddrivenoob you match these information nothing help. just need to match PCB model and program the right firmware on PCB matching with your drive.

Hi, It's a lot easier if you have a picture of the Pcb....then we know for sure if it has external ROM chip or not.

It has the spot for the U12 but I have never seen anything there...

[Cleanroom]

That model does not have a U12 chip, i am looking at one right now

You will need some help with this since you will need to rebuild the rom with special equipment. Unfortunately it is not something you can do on your own.

I have seen a lot of these models with just bad boards.

I am not in Boston, but I am in Austin.

It is not something that will be difficult unless the pre-amp got fried.

You should be able to find someone that can do it for less the $500 if it is just a bad board.

[Harddrivenoob]

The drive does have a spot for U12 but it is empty. I have been told that the information is on the actual processor of the board. Any help would be appreciated.

Thank You

[drc]

Getting back to where I was originally, these drives have unique info in the (not BGA but) large processor on the board. Unless you have the capability to move this processor from one to another, you will need a DR pro to rebuild the info on a new board for you.

I don't have access to a datasheet for the MCU, but I'm guessing that you may be able to hook up a device programmer to the U12 pads, and retrieve the internal EEPROM data that way.

But that's only a wild guess, and I'm not a DR guy ...

[drc]

And what "normal" person do you know that has the ability to do things like that?

As far as I was aware, the only ROYL based WD drives with external ROM chip is Orion family...

And what "normal" person do you know that has the ability to do things like that?

Not that I'm saying it would even be possible. Just that it is out of place in a "noob" thread

I pitch my responses to a wider audience. Perhaps someone reading this thread at some future time may investigate my idea, or provide a definitive answer.

If it weren't possible, would you let us know? I wouldn't want people to waste their time, or worse, as a consequence of one of my suggestions.
