1. # with the following command you prepare your knoppix 3.4 (and higher) machine to mount an NTFS partition readwrite. This command has to be executed only once: 
     sudo captive-install-acquire
  2. Press the ``forward'' button twice to start scanning your harddisk for native ntfs drivers. After a few minutes, the program may crash (i.e., the program crashes on my machine), but this does not seem to have an impact at all...
  3. # once captive-install-acquire has finished, you can prepare the /etc/fstab to include a specific item for your ntfs partition in rw mode: 
     sudo captive-install-fstab -v --add
  4. # you can now mount the partition in readwrite mode with: 
     sudo mount /mnt/captive-noname
