i'm in arizona and the temperature is in the high 110s, i was using my 30gig with a ipod stereo and it was playing fine for 4 hrs, then the music stopped, i checked on it and the ipod was too hot to touch, i know your not supposed to use it in extreme heat, but i thought it be fine in the shade, but now it just keeps showing the apple logo and it wont go into the menu, and its normal temperature now. my mac wont even recognize it, i suspect hard drive failure, but does anyone have any tips?
