circuit board burnt

[DeluzioNFX]

Ok so i have 3 old seagate HD's where the circuit boards have burn mark on the circuit board. i Was wondering if i find a circuit board with the same model #,p/n, firmware and i swap them out.. if there is a good chance that i could get the drive going again? just long enough to recover whats on them

If the drives are the exact same make/model it has a pretty good chance of working.

Another thing I did once when someone had a controller board from a slightly different drive that looked mostly the same was to move what looked like a serial flash chip (it was an 8 lead soic so pretty easy to take off with a hot air rework station) from the original board to the donor. After moving the flash chip to the donor board it was then possible to recover data from the drive.

Same model & firmware usually works pretty well, I've done this swap many times on Seagates.
