I am having trouble with my new Airport Extreme abse station. I want to connect a 1 gig WD My Book drive via USB and share it among the household. I either want to put my media library for iTunes on there or use it for TimeMachine. Problem is that when I plug it in, I cannot see the drive on the network. I had thought it would show up on the desktop. Even in network I have to find it and log in and if I reboot do the same. I was hoping for a more seamless install. Any thoughts?
