Hey, I would really like to add some useful input... but its really impossible without a more complete description of what your setup is... (s2000 cool car btw

)
Saying "my hard drive crashes, whats wrong?" is kind of going to a doctor and saying "I have a pain in my torso, whats wrong?"
It could be a whole heck of a lot of things, and rather then play what could be a very long game of Q & A, if you could list your *entire* setup, complete with a description of how its installed, someone here might spot your problem.
- it could be a bad hard drive
- it could be your ide cord is gettingpulled out
- it could be the drive is not sufficiently buffered from shock, or not installed securely
- It could be a crappy psu, that is allowing unrestricted voltage to go to the hard drive.
- it could be that the drive is installed in an area with too much heat, and its overheating.
