Advertisements Help! So many posts. So hard to tie them all together for an actual solution. My TiVO Bolt 500GB was working fine, until it wasn't. It would not complete the boot. I pulled the drive, initialized it, reformatted it, and copied data to it. So, it seems healthy. I think it was corrupted or something. How do I get a clean TiVo OS (or whatever) back on it so that I can put it back together and see if it works?
