Hi Guys I am about to purchase an apple TV. I will download ATV Flash as I will need the storage extension. I thought I would probably buy a 1TB external Hard drive and use this to store all the media on - Lets call this Hard Drive A. I want to backup Hard Drive A to a second location in case of disc failure. I also want the media to be available to a macbook and a PC in the house (on iTunes) via Wifi. Can I make the second hard drive a NAS drive and keep it in sync with Hard Drive A via Wifi. If I could do this, I would have media available to Apple TV and the same media (albeit on different drives) available to macbook and PC via itunes. If this cant be done, can you suggest an alternative that would fulfil the below criteria: 1) External storage for Apple TV 2) Above storage backed up in case of disc failure 3) Media available to both Apple TV and PC/Mac via Itunes.
