What I mean is the output of the command "mount". When you try to save a file on a hard disk while running the LiveCD the hd needs to be mounted read-write. What I need to see is if the partition hda7 is indeed mounted writable, hence the question about mount's output.

Boot knoppix, open a console, type: sudo mount /mnt/hda7 -t reiserfs
Then type mount and post the output.
