I've had the exact same issue with my WD hard drive in me 21-inch iMac. Everything greyed out in disk utilities no matter what I do. It seems the problem is some kind of adapter that OWC provides. 2009-2010 iMacs all seem to require it for third-party drives. Sigh.

I've had the exact same issue with my WD hard drive in me 21-inch iMac. Everything greyed out in disk utilities no matter what I do. It seems the problem is some kind of thermal sensor kit that OWC provides. 2009-2010 iMacs all seem to require it for third-party drives. Sigh. I am going to call them and ask them if not using this kit will result in the problem we are having.
