I have a home media server now for my Apple TV, it a old Windows XP Desktop, with iTunes loaded on it, with handbrake and several other tools. I now use it for my Apple TV 2. iTunes Media Library is stored on an external Western Digital 2TB desktop edition. I believe it's set to turn off (stop spinning) after 20 minutes of use. And it automatically spins back up when my AppleTV 2 requests to use it through the Computers menu. I'm just wondering if this is a good setup. Alot of my iTunes content is stored on that drive and I'm afraid I'll lose it. I just want to know if this setup is ideal to ensure atleast a 1 year lifespan of the drive (I plan to replace it every year). I don't want to lose my files. As for backing up, I don't have another 2TB drive to back up to, and it's too time consuming to transfer that much data on a regular basis and it seems like transferring that much data would hurt the lifespan of both drives as they are intensely used in the transferring process. By the way the drive is USB 2.0. Thanks.
