Well my 510 downloaded the new P309 firmware a month ago and worked great for about a week until the hard drive crashed. I got an RA# from Dish and a replacement 510 and downloaded P309 onto it. Now,I can hear the hard drive in the new unit spinning all of the time. It never shuts off. I don't think my original receiver did this. Is anyone else experiencing this problem and is this normal? I'm worried this new or should I say previously enjoyed receiver has a problem. When P309 first came out I got the first release so maybe it didn't enable the hard drive to spin all the time and now that the full release is out and the replacement receiver has the newer final firmware it is suppose to do this. Any ideas?
