This is just a cautionary post for anyone thinking of wasting their money on a new 2.5" toy drive in a Bolt. In my opinion there is a BIG reason none of these drives over 1TB are being made anymore - They are simply JUNK. My Bolt (running TE3) with a Toshiba 3TB internal 2.5" drive (MQ03ABB300) is showing major signs of drive failure after only 3 years and two months. While a 3-year drive life is not particularly bad for a Bolt, it is stupidly short for just about ANY 3.5" drive in other TiVo boxes; and this Toshiba drive has widely been considered the best possible option for an internal drive upgrade on these unreliable boxes! Of course we all know that the report of one drive failure means little by itself, but the evidence is mounting that any and all large 2.5" drives in this type of service will be very short lived. SMR drives generally do not work at all, and even the few PMR drives in 2.5" format are suspect. I was happy with my Toshiba drive . . . until the problems started. And that is the whole point of this rant - 3 years is a ridiculously short life for any drive. ESPECIALLY in an application where you cannot make regular backups to recover from the inevitable failure. My Bolt is still booting fine, but I am seeing almost daily reboots, and very frequent screen freezes and extended gray screens that seem to be precipitated by any trick-play buttons or attempts to start playing recorded programs. Tomorrow I will try cloning the existing drive to a new 3.5" external drive and see what happens. It will not be surprising if the clone fails (considering that I already suspect the drive has physical problems), so if it does, I will just start fresh with the new 3.5" external drive to verify that there are not other unknown issues with the box instead of just a bad toy drive.
