I cannot tell you how happy I am, I have just got a stuck disc ejected from the darn superdrive. I am using external superdrive on my iMac, I put in a disc, it started spinning, rev up and rev down, no mounting what so ever, no icon, no stopping. I restart and shutdown/reboot many times, no luck. checked on line for different suggestions and tried many of those, still no luck. That had been 2 hours or 3 hours I had worked on it and I got very frustrated. I was about to give up, then I suddenly had an idea. I pulled the superdrive away from the iMac and plug into my windows pc sitting next to me, boot up, and BINGO!! the disc got ejected when windows was up and running. Guess that it is a good idea to use both windows and Mac together.
