I've had a Tivo HD for several years now with no problems, but last night it started giving me out of space errors. The strange thing is, the number of shows on the tivo is very limited - there's no way i could be at capacity. So i downloaded some program to tell me what was on my Tivo and its reporting that I have 56Gigs of space used and 0 GB free. I know Hard drives recover from failure by marking sectors as no longer usable, which is a probable cause to this loss of space, but before i start cracking open the tivo and taking it out of commission, i was wondering if there was anything else i should try to help fix or validate the problem. Oh, i should mention that i went to Tivo Diagnostics after getting the out of space error, where the screen hung for 10 minutes on "please wait"- i had to pull the plug on it. So technically i've rebooted Any help would be appreciated. Thanks.
