External superdrive not working properly
Hi, I have a 2012 MacBook Pro and I just recently upgraded to Yosemite. My external superdrive will play audio disks in iTunes but, when I try to burn a playlist iTunes cancels the burn with "unknown error occurred (-50)" Also I can't eject the superdrive when I go into Finder under devices. any help is appreciated thanks
MacBook Pro (Retina, Mid 2012), OS X Yosemite (10.10.2)
