Broke my PCB bios chip :-(, lost my chances to recover?

[Jamguy]

Hi,

I was trying to transfer the BIOS chip of my burned PCB to a new PCB I have bought, unfortunately the bios chip failed to come out resulting the black piece to de-attach from its base (image attached).

Are the files lost for good ?

Seagate Momentus 5400.6 500GB
ST9500325AS
PN: 9HH134-567
FW: 0002BSM1
PCB STICKER: 100572173 F

Thanks,

Itay

No.

So, what else I can do, without going to recovery lab that will charge $$$$$???

You have just put another 0 behind the recovery amount, If you value your data, go see a pro before it's to late

Rewrite your documents, redownload what you have downloaded, and use Google Earth / Street view + Photoshop for the pictures.
Alternative : pay "someone" for the technical info you need and do it on your own (technically you are not going to a recovery lab, you are doing on your own).

Beside the humour, I'm afraid you have no chances without equipment.... and know how (priceless)

Good luck.

It's a Seagate.

I agree with mr_spokk, you just added another 0 to the amount you have to pay to recover your data.

Realistically, nothing.

Another good DIY example....

Hi, is that a deccaped chip?, people pay to get chips decapped with fuming nitric acid, and you did it with heat?

Well as people already told you, if you have important data seek proffesional help, if not, look for a fried with a nice microscope to see if the connexions betwee the die and the external pins are ok, then desolder pin by pin without applying more heat to the die or the interior of the chip. This won´t get your data (or you have a very very low chance to get the rom working again) but at least you would have a lot of fun in the process of investigation.

it shoul look something like this but whit 8 pins in your case

He doesn't want to investigate, he wants his data. Anyway from what it seems, THE CHIP is beyond repair. And even if the die was intact, how are you going to make WORKING connections to it ? It is gonna cost much more than professional help, if possible at all (to me the die has excellent chances of being FUBAR too) .
Why concentrate on the poor silicon chip ?

Ok, this is hilarious! Thanks for making by Monday a bit more enjoyable, BlackST!

1) it's not a SOIC
2) when you have some time and a PC3000, try your "method" and report . Let alone SD

[BlackST]

If you say so...

[Mawito]

well, for me, what Spildit said made a lot of sense, if and only if the rom is still alive (yes i know very improvable) he still has a chance of reading the rom with a programmer and transpassing that rom to a new one.

And now link time for those whom like me, like to take a peak inside thing, even when we know it´s wrong:

Here is how people recover data from chips.

Here is how people recover data from chips.

Let me fix that for you - "Here is how people recover data from masked chips" - Masked roms are programmed in the design stage. The diodes and pathways are hard coded as the chip is etched or photo-exposed. This is how early videogame cartridges were made.

This technique of visually scanning the chip and using software to rebuild the data only works on masked roms, or PROMS. PROMS retain data by burning out select fuses in an array. Thus they are one time use only. And the burning-out of a fuse would leave a small mark on or in the die.

Flash roms are not readable by this method. You need to use a form of particle beam disturbance reading, a remote means of determining how many electrons are in a well (or memory cell) representing the data. In modern flash devices it can be as few as 10 electrons.

The best hope in this case is to do a visual inspection of the chip. See if the wires are lifted from the die. They can be put back with a wire bonding machine. This sort of thing is done all the time on expensive custom parts.

Thanks for the explanation, i misstranslate then, i thought that was posible too on normal flash roms.

Thanks for all the replies.

From what I understand, finding the exact board (including exact PCB label) won't work ?

Thanks

compliance is unlikely at 3,5 inch's
sometimes it's possible at 2,5 inch seagate.
Did you try?
