Had a hard crash. Needed to reboot by manually powering off.
Some things that might be related:
-Fix Common Problems says that Multiple Registration Keys are found. I was at trial and just purchased so I should only have one key right!?
-noticed slow file copy speeds, seemed like it was much better up to a couple of days ago.
-I've not run the server without dockers or VM for such a long period before (all day), silly to say but it was something out of usual.
-scheduled mover, various scripts, parity check, file integrity etc to run so hopefully it wasn't one of those.
-A short while before crash, I saw that the Cache drive was spun down while others were active. Manually spun it up as that didn't feel right.
Diagnostics file attached.
Just purchased, and kinda worried now.
