Drives not appearing on desktop I have gone into my Finder preferences and selected to show drives, connected servers, etc., on the desktop. They, however, do not appear. I have restarted Finder and rebooted, but they still are not there. Upon further examination, it also appears that when I click on the desktop, finder does not become the active application, clicking the desktop does nothing. It is as though the desktop has ceased to have functionality other then displaying an image.

Any idea how to correct this?
I believe that CreateDesktop is set to false. Try running defaults write com.apple.finder CreateDesktop -bool YES in Terminal (unless you are on Mountain Lion or below, in which case the command is defaults write com.apple.Finder CreateDesktop -bool YES), followed by killall Finder. You should be able to view items on and drag items to your Desktop now, including drives.
