I just did one of this model today...only had about a dozen read errors after it was cloned. I saved the ROM from the patient and donor PCBs, using PC3K. Then I wrote the patient ROM to donor PCB.

Just remember, the ROM on the PCB is unique to the drive. If you accidentally damage it, it is game over.

how do you realize the connection from the flash?
over TTL? or do u use a direct connection to the flash chip over soic grabbers?

Just as I said, using PC3K. Am I correct in assuming that the data isn't worth $350? You get it yourself, you save a few bucks...you make a simple mistake and the data is lost forever or the cost ends up being 10 times the price.

This company will do it for you for US$29:

If you purchased a replacement circuit board from another store, but did not get the firmware transferred, we can transfer the firmware from the original board onto the donor board for you.

You can move over the ROM chip if you have soldering skills and are able to identify which chip it is. It's an 8 pin chip, if you upload a picture we can help you identify it.

hey,
have a 16 pin soic testclip ...
http://www.mouser.de/ProductDetail/Pomo ... lNkg%3D%3D
... which fits on the 8 pin chip (the distance between the legs of the chips fits).

So i can transfer the bios from one pcb to another without soldering.
http://pdf1.alldatasheet.net/datasheet- ... LSNIG.html
found this technical papersheet - there is a pinout on page 5.

i will try this out tonight or tomorrow...
thank u guys for your incredible help!! :)
