WD Elements & Airport Extreme Set Up?

how do i set up my Western Digital Elements external hard drive with my airport extreme?? i’ve already configured it to work with my Mac computers, but now i want it to be connected to my airport extreme… ive plugged the USB cord in but nothing happens and its not recognized… please help!

You probably should have it formatted for mac that could be a clue. other then that try contacting apple

Same deal, I have a brand new WD Elements 2TB drive.  When I plug it into my Windows7 PC, it pops right up.  I want to plug it into mt Airport Extreme so we can access it from multiple computers.   The Airport recognizes it, but it does not show up on either PC, so I can’t map a drive to it.

This should work.  Any thoughts?
