Disk drive will not accept CD or DVD
I have a MacBook Pro, OS version 10.6.8. The disk drive will not accept a CD or DVD. Thinking that maybe I left a disk in the drive, I tried to eject it, but the eject button does not eject anything. I have not tried to insert a disk for a long time, so don't know how long this might have been an issue without me realizing it. I have tried shutting down the computer and restarting, but this does not solve the problem. I researched using the Apple Hardware Test, but instructions say to insert the Applications Install Disc 2. Unfortunately, since I cannot insert a disk, I cannot approach the problem this way. Any suggestions?
