What this is, if I remember correctly, is some sort of thermal calibration thingy that ... uh ... isn't. I think it's a mechanical problem, not a PCB problem. I don't believe swapping out the electronics here is going to save you. You might ask Rod, or the Quantum Gods. But it sounds like if you want that data you're going to have to send it to a disk-drive restoration outfit. ($2,500 and three days and you're back in business...) Good luck, Brian
