If you format your partition as NTFS, you will not be able to access it from another OS, other than NT/2000 and XP.

This could be a good thing.

If you still wish for the added security of NTFS, format it as such and place all of your "shared" data on another partition.

Here, I chose FAT16, but I recommend NTFS.
