hi. i have this hdd that stoped beeing recognized during a data recovery process. no more read/write or head movements noises.
the drive spins, but i think that there is some problem there, because it is not a clean smoth spinning nois. it is some kind of erratic.
so i checked with COM access.
finally got something from the hyper terminal.

erratic spin is the first clue, find a compatible PCB and change, likely controller chip is bad
