Interesting, I know my son uses NTFS on a RedHat derivative (Centos),
but I see that 8.10 does not have a command line option to make an
NTFS filesystem.

Here are the options I see:

jbuchana@zaphod$ mkfs.
mkfs.bfs mkfs.ext2 mkfs.ext4 mkfs.minix mkfs.reiserfs
mkfs.cramfs mkfs.ext3 mkfs.ext4dev mkfs.msdos mkfs.vfat
jbuchana@zaphod$ mkfs.

( I found those by typing "mkfs." and then hitting tab)

Maybe he formatted and made the filesystem on a Window machine, I know
he shares the drive with one.

I'll ask him at some point, but I'm going to be out of town tomorrow,
with maybe free wireless in the hotel in the evening...
