ResizingNTFS
From OSLUG Wiki
As an alternate Open Source solution, you can try NTFSresize.
If you are installing a Debian system it is available in the new DebianInstaller.
It is also available (outdated version) on the latest Knoppix.
It should probably be noted that it is indeed dangerous to resize NTFS filesystems, and it should probably be avoided if possible.
What I've done in the past was to copy my files over to another harddrive, make my partitions, then copy files back over. Having a friend with a drive they can spare for a while.
EDIT: I stand corrected. Now my note should be to use ntfresize, and not do it any of the old scary, dangerous methods, then :)

From the NTFSresize FAQ:
Q: But isn't NTFS write experimental and dangerous?
A: Not the usage of ntfsresize. There are many totally different NTFS implementations for Linux and people tend to confuse them. [...]
