Can't unmount USB volume

[Eamonn Sullivan]

Make sure you don't have any applications using the device by closing
every application, including any other terminal windows, except for
the one you're using to run umount. When I get this message, it's
usually because I have another terminal open and accessing one of the
directories on the device.
