On Ubuntu- when I mount a file system it automatically opens in a terminal
 

When I mount a file system it automatically opens a terminal with this file system how can I disable this feature?

system settings
 

The following is for the GNOME 3 desktop (different for KDE):

* Click on the little gear at the top right of your screen
* Select 'System Settings ...'
* In the 'system' area (near the bottom) click 'Details' icon
* Click 'Removable Media' then check the box that says 'Never prompt or start programs on media insertion.
