I have a 500GB MyBook external USB hard drive that is plugged into my Airport Extreme Base Station with Gigabit Ethernet as a network drive. So all on one desk I have a cable modem, my AEBS, and the MyBook, all of which throw off quite a bit of heat. I can't turn off the AEBS or the modem, but I should be able to turn off the MyBook. Normally I would drag it into the Trash on the MacBook, but that doesn't turn it off... and just pressing the button doesn't either. Anyone have any ideas on the subject?
