Hmmm, well had the DVR and external enclosure turned off for a half hour, still having the same issues. Sometimes it just reboots, sometimes there will be a message on the screen about an issue with the external enclosure. I got that same kind of message the last time there was an update and once it got up and running, I had no problems for the past few months. I'm doing a red button reset right now, anything else I should try? I vaguely remember instructions about pulling the sat card when doing the red button reset and then putting it in, should I be doing it that way? Great, can't even double-check directv's troubleshooting since their website is down. I'd be happy to never get an update again. Edit 2: Ok, it's not the external drive. I pulled the eSATA connector and rebooted the system, and I'm getting the diagnostic code 14-955. Interesting how a log of other HR2x units are having drive issues at the same time.
