I was trying a Debian Upgrade and my system crashed. So, I had to repartition my HD and tried the Knoppix HD install again. It worked great !!

Before thsi I tried a Damn Small Linux and an Alt Linux Install both didn't discover the partitions. So I guess there were partition detection problems. The can't remove and dev mapp errors still came. However, the HD install still works. I am typing this post using this HD install now.
