I think you have it backwards. You don't navigate based on the drive (BD,HDD0,USB1,etc) all you have to do is make sure that you games are in recognized folders or add your current folder to the options.ini just like barrybarryk said. The bar at the bottom simply tells you were a game is located so if you want to copy it to another location (i.e. Game Disc -> HDD0 or HDD0 -> USB1) you know where it is and how much free space there is. If you want to look at stuff by drive, then switch to the file manager mode to view the files.
