An hour later:

dd: /dev/ad8: No such file or directory
BUT: there was no "ad8: FAILURE - device detached" or similar message
on the console, in dmesg, or in /var/log/*. The disk just disappeared
without a peep from the kernel. What's going on?
Is this repeatable? Does it appear when you reboot and then vanish after
a period of time?
At boot, what does "atacontrol list" say, and what about before and
after you've tried to read from the drive?
