I've given you a few ideas in my last few posts, have you actually tried them?
If your afraid of losing data you can take out your HDD and back that up. If you look around on the net you can buy something called a External HDD Enclosure, and look for the smaller laptop size HDD enlcosures, stick your notebook HDD in there and get stuff off it.
Also tried a seatools scan of your HDD??
