It was flashing in the same manner as if a large write or read were 
occurring - similar to when TM is backing up to the drive - ie, for a 
period of around 30 seconds or so.

Well, that worked (and used grep to filter), but all the events there 
related to the 4 external disks occur after the computer booted up again.
