Recovery from a Seagate microdrive

[sknopp]

I have a Seagate microdrive that came in from a computer repair company. Specs are:
ST612712DE
ST1.8 12GB FW3.01

It was part of a TravelDrive external USB storage drive. The other tech thought the USB connector had gotten worn and pulled it off and resoldered another USB cable to it. The drive still won't recognize when connected. Does anyone know if the board that goes on these drives have EEPROM chips on them that I will need to remove and put on a new board? My thought is yes. They are listed at U2 and U3 on the board. Is there anything out of the ordinary to look out for in terms of finding a donor PCB (aside from the known and documented things)?

Also, does anyone know where I can get my hands on a donor? A quick search on Ebay doesn't show much promise.

The photo is somewhat blurred, so I cannot get a good look at the information on the chips, but I believe the U2 is the EEPROM (Atmel Chip)

To be sure I would search for the data sheets of the chips based off the information on the chips themselves, the EEPROM will be classified as Flash ROM.

Case closed - client balked at what I quoted him for the recovery.

why didn't you just buy a converter instead of messing about with the USB control board?

Guru - are you referring to a ZIF to IDE converter? The board connects to the host via USB, so there is no ZIF to IDE adapter needed. If I was able to locate a donor board the plan of attack would have been to swap EEPROM and then get a converter from there. Maybe I am missing something?

So did you first use a ZIF to IDE converter to make sure that it was the drive at fault?
