Place the hard drive into a baggy, seal it tightly, and put it in the freezer overnight. The next day, remove it from the baggy and put it in the external drive case. Transfer the data from the drive before it warms too much and crashes again.

Restart the computer and when it the computer logo appears, press F2 (or whatever key for your system) to enter BIOS. Change the boot sequence to CD first, Save and then Exit. The Live CD will start, simply follow the directions on the screen–don’t worry, nothing is being done to your hard drive. The OS will start, and you should see your hard drive mounted on the desktop–something like “60GB”, etc. Plug in a second drive and copy and paste the folders over.
