My roommates' laptop is having problems right now. His hard drive has seemed to has died and when he tries booting up to Windows it says there is a disk-read error and doesn't load. He would really like to save the data if at all possible and I had remembered Knoppix, which I downloaded and burned to a CD on my laptop. He tried running it and it will load, the only problem is he cannot see his full hard drive when he loads Knoppix.

His laptop is a standard Gateway 450 series, has the one 30 GB hard drive, and ran Windows XP Home.

Is there something my roommate has to do before he'd be able to see his entire hard drive, or is he just fucked?

Thanks for any help.
