I installed the drive in my mac pro and it works and all, but whenever I press the Eject key it ejects both of my optical disk drive trays, primary & secondary. By the way, I had to remove the original disk drive, Sony 111D, and place it in the secondary bay and place the Lite-On drive on the Primary, upper most, bay. I have no idea if this changed anything settings or what not, but now when I do the above both trays pop out. Anyone have an idea why? Link to Lite-On drive.
