Have a Premiere (TCD746320) that I suspect is failing. It was failing to play back local recordings recently (they recorded fine, played fine after downloaded/offloaded, played recordings on other boxes in network) and after several exhaustive phone sessions with Tivo Support, the only thing left was a C&DE. That restored function enough to record and play, but the box is getting very noisy. I'd already picked up a WD Purple (2TB) drive and dual-bay drive cloning dock with intentions to research and either clone the failing drive or start anew with a base image. At this point, I've lost or downloaded the recordings that were there, and so, I'm not sure whether it makes more sense to try to clone (and later expand) the original drive, or just throw in the towel, and build a new drive/image and move of from there. Dock purchased: https://www.amazon.com/Sabrent-External-Duplicator-Function-EC-HDD2/dp/B00IKC14OG Any thoughts? Can someone share an image of the best match to replace a TCD746320, and then upgrade the capacity using the available space on the new drive? I'm lining up some friends with better Linux/PC knowledge to assist, as I only have a pair of Macs at home.
