Hi, Disclaimer: I put this in the S3 post. I realized it should have been here. I'm sorry, I did try to delete the other post, but couldn't. I have a 160 GB Tivo HD. I upgrade to a 2 TB seagate drive that others said seems to work. It was a green one. I used MFSLive 1.4 (I'm a linux geek so I'm not scared of the cmd line) I used this command: backup -qTao - /dev/sda | restore -s 128 -r 4 -xzpi - /dev/sdb It did a 160 GB but didn't expand. (x should have done that, but didn't) I also got 3 read errors from 3 sectors in a row. I think I then ran something like mfs_add or expand, I don't remember off hand. It said that it used all the storage. So now, it freezed tonight. It also took a long time to boot. It took two reboots (on its own to get to the little Tivo Mascot wallpaper) Any suggestions? I still have the 160 GB drive. So I could go back. The reason for the upgrade was that recently it would not show any video. Like I would have a channel on, and then I got nothing. Video output would cease. So I'd have to reboot.
