One reason why a DVR should be connected to a UPS. Personally, I have never used a TiVo without it being connected to a UPS.I just had a Bolt failure last week. I bought it in early 2016 (Sept 2015 build date). After the house power was turned off and on, the BOLT came up with all the front LEDs blinking. I think this indicates a hard drive failure. As others noted, the unit always ran quite hot, not good for hard drives. After trying a few things, Tivo customer service replaced the unit for a fee. I didn't have an extended warranty.
Now trying to figure out how to go back to the Tivo Classic interface.
