Been trying for the last couple of days to figure out why my superdrive on my iMac keeps ejecting CDs upon boot up, and so far I have found out nothing, but what I did find out, was that so many people have problems with the superdrive in Imac: http://discussions.apple.com/forum.jspa?forumID=1113&start=0 Something is obviously wrong here! How can it be that such expenssive machines, have a component like a Drive of such poor quality? they are cheap to get a quality version of! sigh... Havent even had mine Imac in a month, and have never had such severe issues. Apples customer service so far have been completely useless. Hard not to feel kinda p**sed off. I really like the machine. Most other things have been great, but I didn't expect such... "things" to be problematic. Even if I figure out what it is(which I dont) I probably will have to wonder on when the superdrive will fail since its such poor quality... Should not have to be like that.
