Pointless exclaimative: w00t HDD failure!
Umm, my friend you just might be in trouble. i would suggest booting using something other than your hdd, such as knoppix cd or redhat recovery console for example.
Then run fsck and pray that it will fix whatever error you have on your hdd. if it does not, get the data out of there asap. You can accomplish it via plethora of software included on knoppix disk.
