Hi i work for a data recovery company, does any1 have any questions?

Yes, how can I recover from a WD800BB (Mammoth Marvel drive) with burnt PCB and ROM?

The answer is eluding me for the moment.

(excluding finding a donor with exact DCM, which is nigh on impossible )

PC IMAGE....I am in the same boat as you. Burnt ROM and bad PCB - can't find a donor, I have been trying for 6 months now.

02yellowgt, your ROM is fine. You just need to transfer it to a donor PCB.

no it isn't.....I had someone try to remove it and broke 2 pins off the IC. Heh....it was a tech. at an electronics manuf. com.

oh, that's bad

The drives are easy to find....it's finding one with the EXACT same production numbers to support the bad drive. For example, my drive is WD800BB-22JHC0 and DCM ESBANTJAA. I am no expert (not even close), but it's my understanding that all numbers must match exactly to do a complete PCB swap. Anyone else...agree/disagree?

Thank you VERY much......

If/When you find one please let me know.....

If you'd like to send me the chip, I could most likely repair it for you.

I'm in the UK.

Mine is a WD800BB-00FJA0

DCM: DSBHCTJAH

If anyone can help?

Just a ROM file would be OK, I can burn new ROM from that if necessary

Cheers

replace the pcb with a matching pcb model number found top of pcb near the spindle e.g 2060-701292-000.
NOTE you will need pc3000 to read adaptive information found on small 6 to 8 leg chip and write back to new board. Or simply swap 6 to 8 leg chip near top left of board.

Yes, that is normal procedure! But as I said, the ROM is burnt, so cannot read or transfer

Thanks for the reply though!!

u can also use this

for copying data from damaged ROM and copy it to new ROM .

Its really easy to remove and resold ROM as it has eight legs how can someone break one of its legs ?

So, where's that smart guy? He had so many things to tell us...

Can U read ROM version...?
Pls give ROM (Modules) version...

Mikippp

It turned out that ROM was not burnt.

By luck, I tried the original ROM on a PCB from drive with same model, but different p/n of PCB.

Worked 100%



Did not work on PCB from different model, but same PCB p/n

Yea, it's not that easy to smash this eight-legged bug

yep, even with smoke coming from the Motor Chip and cooking it!

Maxtors - anyone know what the letters in the four letter code reference?
for ex:

K, M, B, D

or

N, M, B, A and so on..
