Device is Mounting as Read Only (Can Copy Files as Root)

Figured it out (thanks to everybody who helped jog the brain a little bit).

Because usbmount is doing the automounting, this is where the problem lay. And, conveniently enough, usbmount provides a configuration file for managing how a drive gets mounted. In order to manage this, open /etc/usbmount/usbmount.conf.

There is a line in the file that looks like this:


Add the uid and/or the gid that you would like the device to mount as.


Now, my drives automount correctly every single time.

The accepted answer does not work for me (Ubuntu 12.04)

However modifying /etc/usbmount/usbmount.conf and changing the line starting with MOUNTOPTIONS, adding ,uid=1000,gid=1000, did the trick for me.
