I got my AppleTV back in March 07. It worked OK, although it could never keep a network connection. Also, if I had not used it for several days or longer it would be frozen and I would have to unplug it and plug it back in (wtb power switch). Well, now the unit is totally unresponsive and I took it to the genius bar today. They plugged it in and confirmed that it was not working. The guy then told me that I was 3 month out of warranty and that they don't replace internal parts in the ATV. I would have to pay $169 to have it exchanged. So, I reluctantly chose that option. After thinking about it and realizing I would probably get a refurb unit, I went back and bought a new 160GB ATV. I also made them give me back my old unit. I am about 90% sure it's the hard drive. My question is, can the hard drive be replaced by a tech-savvy person? I've replaced many hard drives in my time, both desktop and laptop. The issue that comes up is how would I get the ATV software back on it?
