I have been knocking my head against a wall for the past hour. I am trying to plug in a USB external drive and have Ubuntu 14.04 mount the drive so I can write data to it. But the drive is always mounted with root as the owner and group. I have read countless pages about how to enable a user to read/write to the drive but to no avail. The drive is automatically mounted in /media/mark/dive1. I have not created a permanent mount point in /etc/fstab because the drive is, well, removable, so it will not always be connected to the usb port.
