I tried to move a big folder from one SATA drive to another and the machine stopped responding to the point that it lost network connectivity (DF 2.10.1). After reboot, I found the following errors:

I haven't had a chance to run a drive diagnostic yet. I did try a repeat of that same mv command and it happened again. The drive is just a month old, FWIW. Tim
