I have a MBP, I bought it new one year ago and I'm using Leopard. This problem started a few days ago. When I put in a CD or DVD the drive rarely will act normally. Now it seems it won't work at all. It just makes a pulsating sound as if it can't spin the disk properly. Before, sometimes it would make more of a buzzing sound. To get it to stop making the pulsating sound I have to restart the computer and hold down the trackpad to eject the disk. Anyone have any ideas? Just trying to save the hour trip to the Apple Store.
