Not necessarily, you have to choose the filesystem before installing. For all we know, the op may have already partitioned his drive prior to running knoppix-installer. What I wanted to know is what filesystem is he installing to? Matter of fact, I partitioned my drive using qtparted prior to installing knoppix to my partitions, so I never really ran into that problem. The knoppix-installer will reformat the partitions it installs to anyway, so I asked the question because he may have done it differently.
