Just a little side terminology snit here. The 'e' refers to a _partition_
which FreeBSD uses to divide up _slices_ 's1' rather than the other
way around. It is MS that calls slices partitions. FreeBSD slices basically
correspond to MS primary partitions. FreeBSD partitions divide slices
into the pieces on which file systems are created.
Sorry for the somewhat off track comment.
I haven't tried to mount NTFS slices but when I mount DOS FATs as msdos type
I do not use any partition identifier (the 'e' in the above comment) because
there is none. It is a FreeBSD thing and non-existant on a msdos type
slice (MS primary partition, neither FAT nor NTFS).

Good thought. They got us some new desk machines with XP a while back and
I just assumed it had an NTFS like some previous Win2K machines, but it was
actually FAT something and I almost skrewed up when I went to slice it for
dual boot. So, it mounts as msdos type in FreeBSD, not ntfs type.
Fortunately I woke up in the middle of running Partition Magic and noticed.
So, check it out.
