Use hdparm -Y to spin it down immediately, or hdparm -S<n> to set a
duration of idle time until it will spin down automatically. See the
hdparm man page for the -S parameter and more information.
You can set the -S command in /etc/conf.d/hdparm. If you want the drive
to spin down right after booting, do this in /etc/local.d/.
