What does "hdparm -I /dev/sda" show? It sounds like the
drive may
have power management enabled, and is spinning down.
hdparm (thanks for the pointer) shows that idle shutdown was configured
for the drive. A little digging turned a two-hour idle timeout.
Curiously, the problem started after about two hours, but definetly not
idle for that time. I disabled idle timeout, and after two hours I get
the following. Repeats every 15 minutes or so.
