Time Machine Icon on Desktop showing the yellow icon My Time Machine in Finder shows the correct icon, however, on my Desktop, it shows the Yellow icon that is used for normal external hard drives. It only changes on the desktop to the time machine icon when I either eject the hard drive or in terminal use, killall Finder. But ejecting it is kinda useless as I can't use it then, and if I then reconnect it, it shows the yellow icon again.

I'm running the latest version of OS X El Capitan.

Anybody else have this issue or know how to fix this?
To fix this I went into Get Info for the external drive and under the "Preview:" section it showed the TM icon, which I clicked and dragged to the top of Get Info and it overlayed the yellow icon.
