It's NTFS. I originally put all the stuff on it from a Windows machine,
which uses NTFS by default. I have experienced no problems in using it
on the newer Ubuntu machine. But once, I did power down without
unmounting it, and the next time I started it, it complained of an
'unclean demount'. The way I got out of it then was by putting it back
on the Windows machine and closing it down from there, but I don't want
to have to do that in future, as I may not have a Windows machine to do
it on.

This is what it says on the properties tab:
Label: New Volume
Size: 465.8 GB
Media: Hard Disk
UUID: 9C34423634421424
File System: ntfs-3g (3.1)
Mount Point: /media/New Volume
File System: fuseblk
Mount Options: rw nosuid nodev user_id=0
group_id=0 allow_other blksize=4096

It is evidently possible to change Mount Point, File System and Mount
Options in Settings on this tab. Thanks, Rowan
