Thanks for the quick reply.

Actually, I only get this message when right-clicking the Hard Drive icon and clicking Mount.
I did try sudo sth, I think sudo mount /dev/hda1. Which only created the empty hda1 folder.
It would probably help if I knew the appropriate command for this. =P

Bottom line is, I just want to get to the files inside the hd so I can copy them somewhere else and format the computer.

I also read a lot of people talking about /etc/fstab, but I can't find this "fstab" folder.
Do you think getting a newer version of Knoppix would make a difference?

Thanks again.
