The USB drive is already formatted ext3 and has backups on it (hence
its name!).
I've taken the line above out of /etc/fstab, when I reboot the system
I see the following in dmesg:-
[ 20.424000] usb-storage: device scan complete

.... and then nothing. The disk doesn't get mounted, at least I can't
see it anywhere and 'mount' doesn't report anything.
I'm not convinced that things will get automounted (by default) in
Ubuntu Server, remember there isn't any GUI running.
