I recently bought a new TV for my bedroom and decided to bring my silver AppleTV out of retirement. The thing is, as many of you have experienced, the HD runs constantly, even when the device is in “standby” mode, causing it to be extremely hot and increase my electric bill. What I would like to do is remove the internal HD (which I upgraded to a 640 GB SATA a while ago and installed ATVFlash on) and have it run more like my black ATV. I’ve been looking up tutorials on how to remove the HD and get it to boot and run off of an external drive, but almost all of them are centered around installing and running the full version of OSX. That’s not what I’m looking for. All I would like to do is to find a way to transfer the operating system (ATVFlash included) from an internal drive to an external drive (preferably a USB stick) and have it run that way. Is this possible? If so, can someone please share step-by-step instructions?
