I'll bet you don't get a different answer reposting the same problem in a different way other than replace the hard drive. I know you don't like that answer, but that is probably what others will tell you if they pipe in. It is about the only thing you can replace when you start having these kinds of problems. I've got four of the 810's and one freezes occasionally on power up. Should it ever get worse, that is what I'd replace.
