Hey all, I'm hoping for some help regarding the topic in the subject line. I purchased a new Airport Extreme and am using a Seagate Backup Plus 3TB external HD as a backup drive and media drive. I want to share this drive over the network, but it doesn't seem to appear in my airport utility. I had assumed, by Apple's directions, you just connect it to the airport extreme and it appears ready to be shared in the utility. The only naivity that I might have is that currently the ae is being used as a signal extender, as opposed to be directly connected to my cable modem. Any thoughts on the problem?
