Hello, I need help, please. We have imac computer. DVD drive suddenly stopped taking CDs in. I read forums, and other people solve the problem by tapping in the CD. So I did, and it worked. It is now suck it in, plays, eject. BUT if I do not take ejected disk immediately the drive pulls it in again. If I grab it, and take it out, then the drive make this clicking sound non stop, pretty loud. If I leave CD in, then the sound stops. What it could be? Did I brake it? Is there any way to fix it?
