AJG, gparted is a much better choice. You can either download the gparted LiveCD or get the latest Kanotix LiveCD (Kanotix-2006-01-RC4) that includes not only gparted but also additional useful tools such ntfs-3g.

Re-partitioning your drive may be somewhat difficult because it looks like it holds four primary partitions. Please post the output of
Code:
sudo fdisk -l
so I can take a closer look at it.
