1. Why are they do hard to find ? 2. Why are they so bloody expensive. I have a Time Capsule but I'm only using it as a place to store my films for streaming over to the ATV. So I have a 3.5 external plugged in to the iMac (which also needs to be plugged into the mains to run)for back ups but when the iMac sleeps 7/10 times the connection gets lost and I'm left with a message that the drive was not ejected properly. Include two instances of having to repair the disk due to this happening. So now I want a small enclosure to hide behind that doesn't require mains power but I want it to be FireWire 800. I have found some but my god are they expensive.
