la opcion usefree no es reconocida.

solución simple:

from https://bugs.launchpad.net/ubuntu/+source/gnome-mount/+bug/151025

Go into gconf-editor and navigate to /system/storage/default_options/vfat/mount_options, and then remove the "usefree" option from the list. Exit gconf-editor, and try hotplugging your drive again. It works :-)

PD: esto me sucede usando el kernel de feisty (2.6.20) en gusty (para poder suspender correctamente)
