I don't know what mine is, but I'm pretty sure it's dying and I need to send it in before long. Which may entail physically breaking it myself since the problem is something i don't have time to further diagnose (Viva Pinata 2 crashed for Julia repeatedly despite nobody reporting any problems with it). But I need to test another game to see if that's the case, and I don't really feel like sitting and playing anything for hours just to see if a disk read happens to hitch and kill it.
