My 722K died today with the fan running continuously, no boot, and no video. I had a heat warning the day before and nothing has changed in my environment. I have heard no noises from the hard drive and I watched my DVR last night without any issues. I really believe that the problem is not in the hard drive, but in the receiver itself. Is there any way to retrieve the data if the drive is ok? Without a running 722k, I can't copy data to an external drive. Could the drive be mounted on a Linux machine and the data burned into an image to be restored to an external drive? Thanks for suggestions
