Ever since I bought my Mac I've had SSDs in it, now I opted for a drive caddy to replace the internal Superdrive. I'm quite pleased with it, but I only need to access it sometimes, and it's constantly spinning, drawing power and making noise. Is there a way to selectively disable it or set the HDD hibernation timer manually to 1 minute or so? Maybe making some kind of script that disables it until needed? It's kinda just a media drive for my photography and some downloaded movies. Thanks for your help!
