Harddisk partitioner for NTFS

Im looking for a program that can add a FAT16 partition to my NTFS harddrive. I know it is possible, since I have already downloaded two programs capable of doing it. The problem is that those are demos and wont work. Anyone knows if there is a free program that can do this?
There are no free programs that can alter NTFS partitions. Your best bet is to find PartitionMagic. The ONLY program anyone should have if they want to mess around with their partitions.
Agree on Partitionmagic - but just curious, why not FAT32? Unless you wanna run pure MS-DOS (5.0 and earlier) or Win3.1, of course .....
