    Hi guys,
    2010 Mac Pro Quad 2.8.

    1st Hard drive: 120Gb SSD (boot/apps)
    2nd/3rd Hard Drive: 2 x 1Tb WD Black Caviar (Raid 0)

    I think Mac Pro has a feature to put unused harddrives to sleep when not in use. This doesnt work too well when you open up for example, iTunes (stored on non-boot hdd), and have to wait 10 secs for 2nd/3rd HDDs to start up, only to be able to play the content then.

    Same goes with:
    - iPhoto
    - Final Cut
    - Anything which is stored on the non-boot HDD

    Does anyone know how to get around this? (apart from the obvious.. putting those files onto the boot hdd).

    I'm looking for a solution which will keep the unused hods powered on, at all times.

    As always, thanks heaps :D

    System Preferences > Energy Saver uncheck put hard drives to sleep when possible.

    You might want to check "man pmset". This brings up the manual for the command line power management settings. It might be that they just didn't put the option into the GUI but it's still there.
