Just like in UFS, there are structures in NTFS that have to be changed if
the size of the volume changes. Also like UFS, NTFS doesn't place data
sequentially on the disk. A large, mostly-empty, NTFS volume can have data
at or near the end of the volume.
The slicing issue is well-known with NTFS. A reliable way to add a
non-Windows slice to a computer with Windows installed is to use a volume
management tool like PM. If you don't need to resize a slice, use the Disk
Management administrative tool to create an unformatted partition, then
change the media descriptor when you go to install FreeBSD. NT is so picky
it's even recommended that you use the NT boot loader.
