Well Knoppix 3.1 is ancient my friend. Why not get an up to date version? Also why do you use PM to make Linux filesystems? Use Linux to make Linux file systems and forget ext2. Use a journaled fs like ext3 or better yet reiser. Lastly if you want to install a live cd to hdd then Knoppix really isn't the best choice. (see the multitude of upgrade problems in this forum). Try Kanotix and be happy.
