Well I got the dreaded 331 error message on my 622 last night, dead hard drive. I thought it was odd because I've never had any problems what's so ever leading up to the failure. I called tech support and their sending me a replacement which should be here tomorrow. Luckily it's not the main receiver I use, it's a 722k. But unfortunately for my wife. It is the receiver she records most of the shows she enjoys. I just hope she don't lose her mind not being able to record Nancy Grace temporarily.
