Before you continue, realize that you cannot install games to the external drive, or use game saves. You can back up your game saves to the drive (the unprotected saves), and play movies, music, and photos off the drive.
If you want to continue, you have 2 options:
1) Download a Linux LiveCD, such as Knoppix or Ubuntu. These disks include partition utilities. This is probably the easiest as it’s definitely free.
2) Download software such as SwissKnife to partition the drive using Windows. There may be other programs, and I’m not sure of any cost associated with them.
