[ubuntu] Cant mount XFS as regular user

view story

http://ubuntuforums.org – I cant mount an XFS filesystem as regular user. Its only when I $sudo nautilus --> then is the drive on the side panel and i am able to mount. this is the output of mtab /dev/sdb /media/SimpleTech xfs rw,nosuid,nodev,uhelper=udisks 0 0 When I boot into ubuntu, SimpleTech is available to be clicked on. But once I click on it and enter my password it disappears. (Hardware)
