The adding the user to the disk group would have been a desperate 
effort to get the permissions to mount, but seeing as how that isn't 
the problem, this isn't necessary.

Just to be clear, the accessing external devices privileges thing is 
the plugdev group - members of the disk group can do pretty much 
anything to any attached disk, including the hard drive Linux is 
running on. Sorry for any confusion.
