Even though I've unchecked the option to "Put the hard disk(s) to sleep" in Energy Saver prefs my MyBook external drive connected to my Mac Mini still spins down after about a minute. The reason this is annoying is because I use that machine as a server sharing files so whenever I connect to the network share Finder locks up for a few seconds while waiting for the drive to spin up. I've read other posts on other forums which seem to suggest this is now a common problem. That is, OS X seems to frequently (maybe even always) ignore the "put the hard disk to sleep" for all external drives. Does anyone have a solution for this? I just want my external drive to always be spinning so as to avoid the annoying Finder lock ups when I connect to it over the network. Edit: I've also tried the SpindownHD dev tool to set the drives to never sleep, but it doesn't make a difference either and the external ignores these settings and still spins down.
