Heya southperry my mac crashed...

So my little old mac book crashed and when i tried to start it again i got the folder with the question mark flashing indicating that it couldn't find the system files, so i was like yeah k w/e i'll just find buy the install disk. well when i got home i thought well may as well put Ubuntu on it so i can do something...so i put the boot disk in with a fresh download (10.4 or something) and it dosnt pick it up so im like k w/e mac is being a papaya so i power off then on hold option+command+shift+del as all mac users know this picks up any disks ect any ways i hear it spinning away and nothing happens disk stops spinning so i says to myself hmm strange - and i power off and on again and hold c now this should work since it makes what ever is in the disk drive run, well no luck with that either so im like fuuuuuuu hard drive is fucked. now before i go and buy a brand new Mac book pro (I know new hard drive but i need an upgrade any ways its like 3 years old.) is there ANYTHING else i can try is there like a spinrite for mac?

Soooo yep. thats it.
