Corrupted P2 Transfer using a generator.

Hey Folks,
I just got back from a 10 day shoot where we were using a generator. We were using a 3 card CF transfer drive using firewire 800. It is a big device borrowed from a friend, that requires external power(not buss powered). Our file transfers using this device were corrupted, which, due to the long hours, were only noticed on the 3rd day. After lots of trouble shooting we figured out that the fw800 transfer drive was corrupting our files, presumably because the generator was putting out noisy power to the drive's crappy power supply. The transfer drive works great using normal AC power, and subsequently our p2 cards transferred flawlessly with a buss powered card reader.
SO NOW we have 3 days worth of corrupted material that I'm trying to salvage. It has a pixel colored pattern every 2-3 seconds. Picture attached below. Is there any way to fix this with the header? Re assemble the images? Or any other suggestions to fix this? What about restoration companies?

Any advice/help would be a life saver. much thanks!

in dire need of help. Anyone run into this before on a panasonic 4-bay reader? thanks!
