I think I read about this quite some time ago but can't find anything on it now. Yesterday I reconnected my system after moving it to get some carpet work done. Within a few seconds of powering up the 722, I unwittingly pulled the plug and inserted it into another outlet to make room for other stuff... big mistake? After a couple power plug restarts, I finally got the DVR to boot up, and it reported a hard drive failure. Now my 722 is a HD receiver but not a DVR. Is it likely that I did it to myself by interrupting the power during reboot?
