You mount partitions in Knoppix exactly the way that you would expect. By clicking on the desktop partition icon (which mounts them read only by default). Or from a command shell with the mount command. But sometimes windows can muck up a partition so badly that Knoppix can't mount it. Other times windows may have only mucked up the partition table, in which case gpart or testdisk may be able to recover it for you. See man gpart or man testdisk for details.
