@keirFox that's horrible. If you do 'sudo dmesg' it may find a clue. My recommendation is to prioritize remounting the filesystem as read only and not touch it, the below should forcibly remount it as read only. mount -f -o remount,ro /mount/point I wouldn't suggest this except experience rebooting or shutting down is often that it never starts back up. Read only mode may buy you time to get a replacement drive and external drive enclosure so that you can copy over your files.
