Mods, please delete. Resolved.
Xbox Ones have cheap and nasty bluray drives in them. Remember they were meant to be online consoles originally. The Bluray drives have a high failure rate.
I never though of that. I did realize the loud sound wasn’t the bluray drive - the bluray drive was making noise, but the loud buzz was the engine hanging from before I had paused the game (it was coming from the tv).
After forty minutes, I dash-boarded and quit the game. Luckily, nothing negative happened as a result - as far as I can tell.
On a side note, my bluray drive doesn’t always read DVDs well. In fact, if I want to watch a DVD I have better success with the Xbox 360 or older laptop with DVD drive.
