My second 3TB Bolt - a 3TB Vox from early 2018 just died this morning -- I pulled the drive and tested it, it failed SMART based on too many reallocated sectors. The other one failed after 18 months, and was replaced last summer. I called TiVo and they quickly offered to replace the box at no cost -- just the advance replacement deposit (hold) on my credit card. So I put it back in the box and will wait for the replacement to come... Kudos to TiVo for stepping up -- either WD sold them a bunch of dud drives and/or the Bolt design doesn't dissipate heat properly. Hopefully I'll get another year or two out of the new drive , assuming the new box has a truly new drive. I might pick up a 2TB Toshiba before they disappear and keep it on the shelf, since I have two 3TB Bolt Vox units.
