Today I was taking a backup to an external UFS HD when I accidentally touched the cable and it sort of unplugged. The whole system got a panic. While I understand this falls either into hardware or "stupid user" category of panics, is a whole crash normal? Or should I expect better resilience, like fail that filesytem, spit a whole bunch of offenses at me, but keep the on working with the rest, and look for something wrong on my setup? bye & Thanks av.
