SATA drive problem

[Tim Darby <t+dfbsd@xxxxxxxxxxxx>]

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'm guessing this is a drive problem, not a system problem, but just wanted to check with the experts first.  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.
