Tuesday of this week my 622 died. I was about 3 or 4 years old and it was the 4 one I have had since they came out. I called Dish and asked for a 722 as a replacement. No problem they tell me, I just have to "reup" for two more years. They tell me they are going to overnight the new receiver to me. OK so far so good..............Next day UPS comes to my door and drops off a box with the new receiver. One problem, it's a 622 not the 722. Call Dish again, they apologize and set up a service call for a tech to come out and swap out the 622 for a 722 for yesterday morning. Instillation goes fine. Yesterday evening I noticed while watching "paused" TV there was some audio dropout and some pixelation............ switched to live TV and all was good. This morning around 1:00 AM I started hearing the new receiver making noises......non-stop noises until 5:00 AM when I turned on the receiver. BIG ERROR MESSAGE - HARD DRIVE FAILURE. Three resets later still no hard drive. Two phone calls later I convince customer service that they should have a tech come out and do the swap out instead of me having to wait a week for a replacement shipped UPS. Is this hard drive problem common? The unit had less than 3 hours on it.
