It was a 16GB flash drive, NAND on it is 32GB.

PC3000 :
IDs / Reads / ECCs / ReadRetry (700mb invalid sectors) / No XOR

Without XOR it's a dead end and "extract" doesn't appear to work.

FE :
IDs / Reads / ECCs (FC1178 1154_1150) / XOR (21cd mix).

Find mix, finds nothing. Raw gives jpgs about 30% good up to 1mb, no bb file gets created.

I need the file system on this one too as there's organisational structure in it, without it the data is useless to the client. Can anyone point me in the right direction or even have a working FE model for this combination I could purchase ?

If there's no XOR do you see any FS structures in hex?

By no XOR what I really mean is no XOR found in PC3000. The data must be XOR'ed as 21cd removes its in FE. 1154_1150 Xor 21cd from the layouts doesn't though I had to use 1154_1150 and then apply xor 21cd in the mix, not sure if the difference is an order of operations thing?

PC3000 has two xor 21cd's for FC1179 - page layout looks wrong on one and block size wrong on the other.

Not had chance to look at the assembler in FE yet, Im not 100% sure the mix is right.

FC cases is pain in the a**. Most cases need cut bad bits (if you get some good data by RAW it means that fortunatelly you not have it at dump), cut pages etc.
EACH ONE case need individual solution. Stucture is another story...

We can solve most cases with structure, it depends on many factors.

I don't think there's enough cash in the case for me to fully outsource this one unfortunately, will check with the client though. I keep asking clients to send me in easier cases - but this is what they give me.

It's more than some good data it's about 2500 jpgs, I wanted to do it PC3000 as I still find it easier to visualise what Im doing in there.
