EDIT: Downvoters, please explain to me what is wrong with the question, so I can improve it. Thank you.
I'm trying to change the default permissions of some automounted USB drives which are VFAT, and by this image:
http://ubuntuhandbook.org/index.php/2014/07/mount-partitions-automatically-ubuntu-14-04/

... I guess that I could do it from gnome-disks. However, this PC is:
$ cat /etc/issue
Ubuntu 12.04.5 LTS \n \l
... and so it doesn't have gnome-disks, it has palimpsest instead. So I tried opening both as regular user: palimpsest, and as root gksu palimpsest, but I get the very same screen:
That is - there is no cog icon anywhere, there is no "Edit Mount Options" anywhere either.
So I just wanted to make sure - does palimpsest in Ubuntu 12.04 have a cog-icon/"Edit Mount Options", but I have my PC misconfigured (i.e. maybe I have missing packages) - or is it incapable of changing mount options by default?
