The SuperDrive on my G4 laptop started sounding like fingers scraping on a chalkboard. I knew it was a matter of time before I was going to lose a cd or dvd in it.
Repairs went very smoothly except for two items: 1. finding the recommended #00-1 phillips screwdriver. The #00 from my Craftsman tool kit was way too big, so I borrowed a #000-0 from a friend who builds a lot of items in miniature. A spudger is basically a wooden popsicle stick. Once all the proper tools were located, the job is pretty straight forward. The new drive went in very easily, and has worked quietly and flawlessly. Instructions were very good, and I just used my iPad to display them while I worked on the G4.
There was one issue that I would recommend adding to the instructions: After the keyboard has been removed, it is a good idea to mark the position of the PRAM battery before using the spudger to remove it. If is not placed exactly where it was, the keyboard will not reinstall properly. Also, to make sure that all the screws go back into their appropriate positions, I used a small 10-holed plastic painter's mixing palette to keep the screws separate, and in order, one hole for each step where screws were removed. Tweezers were also a huge help in holding onto the very tiny screws.
