Well, for about 100 bucks, you can get a new hard drive. If you look around, there's something called Norton Ghost... install that on your bad hard drive, and it will copy it to a new HD.
If you put the crappy HD in a baggie, put it in the freezer, it will work for quite a while before it heats up and fails again. That will give you time to install Ghost, figure out how it works, and to time how long it takes before it bombs out again. Refreez and give it a try!
