-If you don't want to allow non-root users unfettered access to mount and unmount drives, you might also consider writing a shell script which specifically mounts or dismounts only the drive you're concerned with, and then use [[sudo]] to allow users the privilege of running that script as root.  If you do it this way, be CERTAIN that the script is owned by root and chmod 755, so that noone can edit themselves some "extra" things into the script before running it as root.

 For my personal computer, I gave myself full sudo privileges and added an alias to my shell config allowing me to quickly "dock" my usb drive in my home directory:

+Removable drives can be mounted by root onto any directory, and here is how to mount drives without user privileges. Generally, they should not be automounted at startup, because they are not always connected.
 For information on mounting a usb stick see [[USB storage]].

 It is worth noting, however, that giving unrestricted NOPASSWD sudo privileges to a user is an egregious security violation, as it makes it possible to compromise the system at a root level with only a single account and password.
