I have an HDVR2 that was freezing & occasionally rebooting, so I reluctantly went ahead with a "Clear & Delete Everything". It's now been over a week that it's been showing that it may take "up to an hour". What should I do next? This unit doesn't have anyhacks but does have upgraded disks (2x120GB). Should I be using the kick start codes for re-formatting? Thanks for the help!
