Superdrive doesn't accept discs
For some reason when I try to insert a disc into my drive slot, I can only push it in about half way and it feels like it hits something. There is not a disc in the drive, as I just ejected a disc before I had the problem. I tried the terminal command to force eject and it didn't seem to help...
I have a mid-2010 iMac (21.5", Snow Leopard) and a similar problem. Today I decided to copy a music CD to my iTunes library. It worked and I ejected the disc. However, I was about to put another CD into the Superdrive and it did not go in. Just like with GatorsUF, the disc went half way in and then hit something soft but firm.
I've owned this iMac for about a year and this is the first problem with the Superdrive (which I do not use a lot). I've tried to shut down the iMac, checking the disk and repairing the disk permissions -- and obviously trying out different CDs and DVDs. It occurs to me that the problem might be that the Superdrive for some reason does not know it is empty. I've read that through Windows (bootcamp) you can eject with the Superdrive ejecting even if it is empty. However, I do not have Windows on this Mac and do not know how to eject when the drive is empty.
Any suggestions?
EDIT: Found a cure: click and hold left mouse button while booting up.
