I was going to burn a CD but then I realized I did not have all of the songs highlighted in iTunes that I want to burn so I canceled the burn and the disc stayed in so I just highlighted the songs I wanted and clicked burn again but it told me to insert a blank disk. There is already a blank disk in there, and the computer doesn't even recognize that there is a CD in it. Not on the desktop, in disk utility, or in iTunes. Pressing the eject button doesn't work on the keyboard or by doing it in iTunes, I read about it online and it said to try the following: Type "drutil tray eject" or "drutil tray open" in terminal. Which also did not work. How do I get the thing out!?!
