On a tangent, does anyone know how to perform recovery on a HDD that is not detected by the bios (e.g. due to defect/damage on the pcb)? I have a 500GB IDE Hitachi Deskstar drive (was originally in an external USB caddy, but now taken out) that I think has suffered overvoltage. Even though there are no visible burn marks on the PCB, when connected directly via IDE to any PC I try, the PC will not powerup let alone POST, which indicate some short-circuit perhaps? This happens even if IDE cable not connected, which leads me to think of overvoltage damage (could be wrong). Replacing the PCB with one from an identical drive does not work due to the fact on most modern drives the PCB microcode is unique to the specific unit itself (swapping PCB with an identical unit [make, model, batch, MLC, all same] results in drive spinning but no detection in BIOS or even by the manufacturers own drive fitness tools).
