I had an ordeal with my 800 tonight. I had it sitting on my desk and I was unhooking it to bring to bed with me. I was taking off the antenna connector and it hung and caused it to turn over my desk. It scatched the soft front cover just above the display, but the major thing was that it must've knocked the SD card loose. I hooked it back up here in the bedroom and the card went corrupt. It would not reformat & reload for several attempts. I was beginning to believe I damaged it but it finally formatted & reloaded and is now working again. So be gentle on them!
