My superdrive seems to have the problem of not wanting to take disks. I can insert the Snow Leopard DVD and it will take it but its like it has a hard time. It acts like the black things between the drive and the outside are in the way and it is having a hard time ejecting/inserting disks. If you try to put in a new disk, it won't take it, but after it spit it back out, if you put it back in, it takes. I wonder if it was because the disk was holding the velvet things open? I hardly ever use the superdrive in it since I mostly do DVD burning on my faster PC drive so I don't know what the problem is. Seems to have started happening after they replaced the top case because it cracked. Any help is appreciated.
