It's in a dedicated plastic case. I used sudo shutdown -h now and waited a good 60 seconds before pulling out the USB-C Power cable.What sort of case is the Pi in?
Is it metal by any chance?
You should make sure that you shutdown correctly before switching off the power. That's true with most computers. Pulling the power when the system is still writing to disk; is likely to corrupt the disk. It sounds like you are doing that.
I have some Pi's that I leave on pretty much all the time and others which are constantly being turned on and off. I don't have any specific procedure that I use.
Can you reformat the card on your Mac/another computer?
What SDcards are you using?
I am not familiar with NUT...but I know a man who is....

Might be worth having a look...Jeff is good IMHO.
The SD Cards (genuine SanDisk Ultras I have had for some time) are completely dead - cannot read them on either of my Macs. I am not too troubled about losing the cards. What I AM troubled about is going through all this again only to lose yet another card - and of course a lot of wasted effort.
I doubt it has anything to do with the NUT configuration. I am leaning towards the fact that when I plugged back the USB-C power cable, it was already plugged in at the wall socket and somehow plugging in a live USB power cable fried the SD Cards. It is going to be a costly way to find out though, if this hasn't happened to anyone else! :-]
