I'm running out of HD space on the atv I wanna get a 1tb or 2tb for it eventually but not in the budget right now. I have a 120gb IDE in an external enclosure would this work for right now? I don't wanna waste the time nodding the atv to take an external drive if it'll be too slow to use. Also will atvusb patch stick maker work for this? Don't wanna spend $50 for atvflash.
