    I have a 27" iMac with four USB external hard drives attached. The drives are working fine, but one of the drives takes a long time to wake up after it hasn't been used for a while. The other drives are accessible from the Finder almost instantly, but this one drive causes the spinning ball for about 10 seconds before it is accessible. Not a BIG deal, but it happens all the time even after relatively short periods of inactivity.

    I thought maybe I could uncheck the "put the hard disks to sleep when possible" option in the Energy Saver preferences. But this would presumably affect all of my drives (including the internal) and that might lessen the longevity of the drives, right?

    Are there any options for just turning off the sleep for this one drive, or perhaps a way to shorten the wake time?
