In my nautilus, I have this annoying drive labeled "Ubuntu 12.10 i386" and when you click on it, it gives the 'cannot mount' error. With a little GParted research, I found out that its the Extended partition containing the SWAP partition. Since it's obviously not of any use to nautilus, how do I make it stop showing up as an unmounted drive, or at least hide it?
