I think it's probably a bug of Gnome, because, if I try to mount my External Drive manually, I have not got any errors ...
I have looked the 'dmesg' and the scan of my External Drive return any errors too ... The message is more or less of Gnome is : "Cannot mount : This drive is mounted without the good options". -- Cannot automount External drive in GNOME https://launchpad.net/bugs/76145 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
