I've been down this road before with the TiVo Bolt (the white box). I tampered with it and basically screwed it up., I think. Well, maybe it would still work with the original hard drive. I don't know. PMR vs SMR drives might've been the issue. Fast-forward from my post from May 14, 2016 to Sept. 30, 2016, I purchased a 6-Tuner Black Tivo Bolt+ with 3 TB. The thing had been working decently until Thursday July 12, 2018. Up until then, I have to admit that my recordings had spots of stutters, that is, I think you call it screen tearing and temporarily losses of picture and audio, we're talking very sporadic drops that lasted up to maybe a second, and unusual noises from the hard drive that I didn't notice from the TiVo Bolt (white box) with the original hard drive. I purchased the lifetime subscription of Tivo and I did not purchase a warranty. Figured I didn't need it...of course, like everyone else thinks the same way, and what do ya know, maybe I've got a lemon. Has anyone else had this happen to them? That is, their TiVo DVR essentially dies from a power outage. Should I call TiVo and see what they say? I'm worried about their policy about transferring subscriptions over (they say you can't) to a new box. Rather than trying to open up this box and messing with it (assuming my hard drive went bad), I'd rather just buy a new box. Just for kicks, does anyone know what hard drive is used in the Bolt+ in case I do decide to attempt replacing it?
