I don't use all the disks in my PCs all the time, so I'd like to spin down the ones that don't get used much. I don't want to use power management to do this as that applies to all disks, and regular spin down/up cycles puts extra strain on the hardware. Anyone got any ideas? I found some really old shareware that might work, but I'd prefer free if possible. After all, I can do this in Linux for free.
