Replacing the optical drive in an iMac
Il Mio Problema
For a while, the optical drive in our iMac didn't want to eject discs occasionally, which we coped with by inserting a couple of thin plastic cards while hitting the eject button. The drive eventually progressed to not reading discs at all.
La Mia Riparazione
The repair was straightforward. I had replaced the hard drive previously, so it wasn't nearly as scary opening the iMac this time.
Il Mio Consiglio
Be careful when you are removing and replacing tiny screws, which have a tendency to run for cover inside your computer when dropped.
