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.
