disabling optical drive on imac 21.5" Mid 2010 running 10.8.3
My iMac optical drive is faulty. To get around this problem I have an external LaCie drive connected via FireWire. When using Toast to make DVD/CD copies the Toast application attempts to use the internal Optical drive. Is there any way I can either disable the Optical drive either through OSX commands or Toast Preferences?
iMac (21.5-inch Mid 2010), OS X Mountain Lion (10.8.3)
