Change graphical representation of the drive

when looking at the bottom area of a graphical representation of the drive(s) I can see the "used" part of the disk - but having a percentage on the graph units (followed by the actual bytes left /used) might be a more visual way for newer users to understand their need (or don't need) for another or a new disk. Have not run into any problems as of yet - looks good - really like the menus - way to go!
