Energy saving setting not respected by external drive

I have an external optical drive which sleeps every free second, although the "Put disks to sleep" setting is turned off.

Solution?

I always thought that setting was for hdd's. have you checked the settings for USB power saving? Also most optical drives will spin down as soon as a read/write cycle is complete.

I can't find it. Does it even exist?
