sorry that the reply is in english, meine deuch...
you could use qtparted (as root) to format, partiton... the drive, then you edit /etc/fstab to get it detected each boot.
OR you could use Fdisk or cfdisk to partition... and then mke2fs -j (dev/.... or whatever Filsystem you want.
and you could mount the partitions manually each time aswell.
that is
sudo mount -t filesystem /dev/whatever /desired/mount/point
all these things have to be done as root (su or sudo alows you to do them as user in knoppix)
