Thanks, whilst I suspect not affected in the slightest, I checked and noticed one of my SSDs (both Crucial) had out of date firmware, and since I use Linux, I had to get the bootable iso to update, which is tiny and not interactive.
I also didn’t backup, so scared the living crap out of myself whilst I set it off to update.
Fortunately, all went well and the drive is updated and fine.
Arch Linux, on a Ryzen 7 1800X, 32 GB, 5 (yes -5) HDs inc 5 SSDs, 4 RPi 3Bs + 1 RPi 4B - one as an NFS server with two more drives, PiHole (shut yours), Plex server, cloud server, and other random Pi stuff. Nice CoolerMaster case, 2 x NV GTX 1070 8GB, and a whopping 32" AOC 1440P monitor.
