This is exactally what Im looking to do with my home network. So does that 500gb drive house your iTunes library as well as back ups? So everyone can back up to that drive as well as access that drive to control iTunes?
I wanted to do the same thing but add another 500gb drive dedicated for back ups and have the other drive just for media storage. But If I add 2 drives, can one of those drives back up the other? In other words, if I have a dedicated media drive, can the other drive be used to back up my machines as well as my media drive? Anyone know?
Also, txhockey9404, did you get a USB hub in order the use multiple USB devices with your Airport Extreme? And what kind of 500gb drive did you get?
