3 external disk - one should not go in sleepmode

[wunderbaren]

I have three external disks on my iMac, on one of my disk my whole music collection are, adn when i have iTunes open i dont want my disk to go to sleep, beacuse its really annoying when itunes hung up everytime it go to sleep.

But i want the other disks to go sleep.

Any tip?

I don't know of any way to do it from menus. There has to be a terminal way to do it, but I have no idea about a lot of the terminal underpinnings. I use the utility called Cocktail, and it has an option to set a time for hds to sleep, but it applies the setting to all the drives. So, I think you'll have to search for some terminal commands.
