hdparm doesn't spin down hard drives connected over USB.  (It probably doesn't 
work over FireWire either, but I've not checked.)  sg_start (part of sg3_utils) 
will spin down USB drives; it's what I use (within a shell script run as a cron 
job) to spin down the external drives that I use for movies and music.
