Hi John! I would check out some of the documentation on the gvfs... However you can try gvfs-mount --unmount /<location>/ where <location> is the actual location. You can also use gvfs-mount -o to watch what it is dong when you plug it in. (it monitors the output) man gvfs-mount will give you more information. You can also type man gvfs<TAB><TAB> (Use the actual TAB key) to see all the gvfs related commands listed. This should at least get you pointed in the right direction
