If you don't have permissions to see a drive, you can set permissions as root in the terminal:
(Change "user" with your Linux user)
# chown -R user:user /media
# chmod -R 775 /media
EDIT: Although I was happy to help you and solve the problem, I must also say that this could also be a security breach as long as everyone else in the computer can see and run every media file inside the
/media tree path.
If you have more users, or simple want to keep your files away from other's eyes, check the meaning of the permissions and set them accordingly.
chmod -R 750 to be allowed to do everything to your files; everyone else in your user group, can watch and run; and the rest, well, could not even watch if there is any folder, even less what stuff there is inside them (again, unless you give them permissions).
