Hi, I have a 2011 MBP with in the hard drive bay an 120GB SSD and in the Optical bay an optibay with my original 500GB HDD. There's not much on the HDD only movies and tv shows so I would like to be able to put the disk in sleep mode, or unmount it. I've done some research and I found that the only way is to use a script. How do you do this? I can't seem to do that, any explanation would be appreciated. Now I've found something else, but it doesn't work for me, someone found a way to sleep the hdd when not used. But every time my hdd goes to sleep, it will wake up a few minutes later, even when I don't do anything at all... Does anyone have a better idea? It would be so nice to have a program or something in the mac menubar where you can toggle sleep mode for the second hdd, does this exist? PS I'm using OS X Lion Thanks in advance!
