Q: Enable disk sleep for a specific optical drive (not global sleep)?
I recently updated my Mac Pro 3.1 P-ATA optical drives to S-ATA. They are all working fine, now that disk sleep is DISABLED in Energy Saver Preferences (same as sudo pmset disksleep 0, in terminal).
Hower, with this GLOBAL disk sleep disabled, none of my spinning HDs go to sleep. This is both pulling extra 4x7.5W of energy and causing a lot more noise to come out from my computer.
So, my question:
Is there a way to DISABLE disksleep for a SPECIFIC SATA device?
That is, not to enable global disk sleep, but select which drives to go sleep (and at which interval)?
pmset does not have this option. Only global sleep.
Is there another way to put specific disks to sleep? Perhaps with a 3rd party utility?
Mac Pro, OS X El Capitan (10.11.4), MacPro 3,1 - ODD @ SATA 5 & 6
