I just got back with my 4th 8300 in less than a year. I don't over use it, a few shows here and there. No heat issues, not enclosed, nothing on top. I use the auto powed down feature, so it is on quite a bit every day. What's going on here? It's always been an issue with the HardDrive. Anyone else experiencing this? This is getting a little out of hand. At what point do I start "raising my voice"?
