I'm running out of space on my Mac Mini's disk because of all my iTunes video files. I am thinking about buying an enclosure for my spare 1 TB hard drive, and using it as the location of my iTunes library, but I wondered how it works with the Mac Mini's energy-savings mode. My Mini is set to sleep after 15 minutes of inactivity, then wake when iTunes content is requested by my Apple TV or Airport Express. I like it, because it's very energy efficient that way! My question is, will the disks also sleep along with my computer, and will they wake properly when the computer wakes? Is anyone doing something similar?
