Advertisements My 3 tb lifetime boIt I bought new in 2018 just had a catastrophic hard drive failure. I had a large 120 mm fan underneath bolt all this time because I knew it was running hot. When I turn bolt on I get four flashing lights but even worse there's loud grinding signs inside the TiVo. Should I replace my bolts hard drive with a spare 3 terabit Toshiba Drive I have or take advantage of tivo's offer to swap my bolt for the two terabit Edge for $100? Do I lose the ability to transfer shows to PC. If I swap my bolt to Edge?
