I experienced the same issue - it worked all the time under 9.04 and 9.10, and suddenly started. However, for me it helped to run the storage device manager, and used the 'assistant'-function to allow any user to mount and unmount the disk. This immediately solved my problem. Hope this helps you, too!!
