Comment 5 for bug 1698630

You might create an icon on the desktop or in the menu system with the command line parameters that you desire to only access a USB drive when it is plugged in.

For example if you have two internal hard disk drives (/dev/sda and /dev/sdb), then a newly inserted USB drive should receive device path /dev/sdc. In this case modify the icon parameters to pass /dev/sdc to gparted.
