MyPassport showing up as WD Smartware but not an actual drive on PC

MyPassport is showing up as WD Smartware but not an actual drive on PC.  The Passport is currently formatted for Mac, but I now need to be able to use it on my PC.  When I open the Disk Management, and right click on the drive, it will not give me the option to Format it.  Any help would be great.  I have attached an image of the Disk Management.

Find your drive on WD site and download the format tool and see if that will work. Make sure you are not connecting through a hub or using a cable longer than the original.
