Yes - it's not actually automounted until you access it. Notice that if
you umount a USB device from the console, it will still be displayed in
Nautilus. GNOME displays devices that are 'connected', not just ones
that are mounted, and when you hit the 'eject' button in the GUI it
doesn't just unmount them, it actually entirely disconnects them so far
as the kernel is concerned; if you plug in a USB device that's,
say, /dev/sdb , then hit the Eject button in Nautilus, you'll notice
that /dev/sdb doesn't exist any more. (This is a minor pain if you're,
say, writing a live image to a USB stick; you have to 'umount' it from a
console, not eject it from the GUI).
