? hard disk failure- how to recover data

[ghosthunter]

A technique I read somewhere is if you bring the temperature of the hard drive down to the freezing point by putting it in a freezer first and then taking it back out, somehow the condensation from bringing it back to room temperature helps revive it for about 20 minutes, it can be repeated about five to six times tops. Long enough to get out any important files that need to be backed up.

this is only if the problem is the HDD's bearings.

There is no condensation happening inside the HDD itself because its a sealed environment. The danger here is condensation forming on the HDD's controller board causing a short-circuit is greater.
