Bad sector - the disk has lost the data on some blocks. Thats a physical
disk failure.


what's somewhat weird is that the disk _seemed_ OK (i.e. no errors that I would notice, nothing in the syslog) and then suddenly the disk does not respond at all, I tried dd_rescue and it ran for hours (more than a day) and it rescued absolutely nothing. Is it possible that the disk surface is OK but the electronics went bad? Is there anything that can be done if that's the case? (I have another disk, same model).

You probably void your waranty on both drives if you swap the control board, it may require special tools you don't have, and I have done it in the past. Can you get to the point where it fails and cool it with a shot of freon (or whatever is politically correct these days)? May be thermal, in which case you run it until you back it up, then waranty it.
