I took the leap yesterday and replaced my little used superdrive with an OWC DataDoubler/HDD-combo. That's a great piece of hardware, by the way. Everything's in working order, but not quite to my likings overall. I've an SSD in the main drive slot, trying to keep battery drainage to a minimum. But that measure is compromised by the fact that the hard drive automatically spins up at power-on, sucking battery and making noise. I don't want that! Is there a way to prevent the system from powering the drive until I myself want to access it in OSX?
