Fujitsu mpg3204ah firmware help needed

[bones]

Hi Guys,
I need a bit of help with a drive I have. It's one of those Fujitsu mpg3204ah problems.
Basicly it died! It can't be seen in the BIOS and the drive motor will not spin up.
Fitting another board with the wrong firmware will get the drive motor going.

I have tried the freezer idea, the heating of the chip idea and the MHDD software(can detect it).
So I'd say it's a board fault, not firmware. (Maybe)
I have 4-5 other fujitsu drives with the same board but different firmware. Which I'm going to trash after I get the data off this one drive. If anybody needs certain firmware boards let us know.

My question/s is/are what software/hardware do I need to rewrite the same firmware of the bad board to a working one?
What are the steps are needed to do this.

An other option I see is a firmware chip swap. I'm an Electronic tech by trade so surface mount soldering is fine for me.
I'll try the software options first.

If I went this way which chip is it that holds the firmware?

Or are there any other recommendations that anybody can suggest?

Cheers

Hi,

IMHO the SW method of ROM writing is much more complicated than swapping some SMD ICs especially if you are experienced in SMD soldering.
These boards usualy have M28F102BB Flash.

success!

Hi,
Thanks for the info. I'll change the chip over then.

Hi Guys,
Thanks for the info. I changed the chip and I got my data back. Thankyou very much.
I made sure that I used a board that had the eact model of the larger chip and same brand firmware chip.
Doing this chip change isn't for the faint hearted. If you haven't worked with surface mount, lots of surface mount then get someone who has to do it.

I'm going to trash all the drives I have but keep the boards incase some one needs them.
I'll list the firmwares later.

Cheers
Rodney
