Google is right ... what does Pete always say "Google is your friend" ?

Anyway, if you are using a Firewire drive that is one of the things you
might find "breaks" the sleep. The Firewire drive will wait forever to
ramp up to speed if it gets a sleep signal and vice versa. I found this
out the hard way with my 3 200 GB firewire drives. Now I just let them run
continuously.
