First you can shut off caps lock, it honestly makes you sound like an idiot. No offense.
Obviously, your hard disk is damaged. You'll have to replace it to get the machine working normally again, but the disk you have is probably done for. You can attempt to plug it into another machine or use an external interface to save your documents - but it's most likely that your documents and such are un-retrievable unless you've got a pretty big bankroll.
Replacing a hard drive is easy cake. Just remove the tray which usually just contains two screws. Take the broken one out, put the new one in, and presto! I agree with frozen though, please lay off the caps... We check posts, and yours didn't stand out anymore than the other just because you had caps... It was just annoying to read.
