Spin down hard disks


I have several hard drives on my computer and I would like to spin-down some, but not all, of them. Is there a way to individually spin down the drives via a UNIX (cron) command or via Applescript?

Thank you.

Easy/Safe way is to let the energy saver spin it down so you don’t accidentally spin it down while it’s active. You can set the spindown timer to something low, like this…

In terminal:
% pmset -a spindown 4

man 1 pmset for more info…

BTW, that’s a global that effects all drives.
