External drives not spinning down under Mavricks
I have 2 external disk drives (LaCie) connected by Firewire 800 to my iMac. Under Mountain Lion the drives would spin down when not in use or when the computer was put to sleep. After upgrading to Mavricks the drived will not spin down even when the computer is put to sleep.
Any ideas?
