Disable hotplug/mount-notification for one specific device?

["Sven K." <intelligenzfluechtling gmail com>]

Hey,

I'm using a bash backup script which mounts a partiton, makes a backup and unmounts the drive then again. I use notify-send after and before the backup, but I want to hide the "mounted"-notification which appears since Gnome Shell 3.2.

Is there a simple way to disable the notification for that specific partition?

Thanks!
