On Saturday last, I replaced the failing 3TB external drive on my Genie (HR34/700) with a new 3TB external drive. I followed the instructions I found here: http://www.dbstalk.com/topic/158213-removing-replacing-copying-hard-drive-of-hr2-receiver-photo-tutorial/ It worked beautifully and now I have smooth TV and uninterrupted video playback. Unfortunately, since I switched the external HDD, the Genie reboots daily at 5:04p (CST). FTR - I have not changed any of the electrical setup (a substantial power conditioner that feeds the TV and a small UPS where the external HDD and the Genie are connected). Any suggestions on the cause and (more importantly) the solution?
