I think I may have found the issue.
I always set my power settings to “Never”.
That got changed somehow.
Somehow I found a power setting that was shutting down my HD after 20 minutes.
That should be “20 minutes” of “inactivity” keyboard or mouse.
So, if I’m watching a Youtube video and I don’t touch the keyboard or mouse ? It maybe shutting down as a result.
In addition, while going through a hundred or so “updates” It would always crash.
I’ve had this problem before when running auto-updates with NT machines that had a “Sleep” feature turned on.
Set it to not update automatically too.
Inactivity of the keyboard and mouse, not the broken ones I hope. You said you use external ones.
