I haven’t had disk issues, am running a 980 Pro SSD currently, but I’ve definitely noticed other weirdness that sure feels more like that? Half-Life crashing repeatedly in map loads sometimes succeeding fine and other times not. Firefox broke wholesale until I reinstalled it and even then had to do a refresh to fully solve it. I haven’t seen anything else weird thankfully but this definitely has me concerned and glad I’m backing up with a very long rolling period just in case. Gonna uninstall this update for sure.
