Having a faulty hard drive?

Before you go out and spend hundreds or even thousands of dollars to recover those precious data in that broken hard disk, try this method. Put your hard disk in a zip bag, put it in the freezer overnight, take it out and quickly put back to your CPU and try run it again. Do mind the condensation and it's highly effective. If it works, do transfer the data to another disk and discard the 'broken' one, since it's a 'temporary' solution. But it's enough to recover those data.

But do remember that it's not a guarantee. So do it on your own risk.
