    We just received a refurbished Macbook Pro, and on the first time turning it on we noticed the optical drive was sounding as if it was trying to load or unload a disc, but the eject tool wasn't doing anything. Eventually a disc popped out labeled "Apple Thick Disc 691-5835." Does anyone know what this might be?

    It looks like it's probably a master image for restoring the computer to factory settings. Why don't you put it back in the drive to see what's on it? You can force-eject a disc by holding the trackpad button right after turning your computer on in case it doesn't want to eject.

    The number on it looks like a phone number. What happens if you put it in a Mac and see what is on it or what it does.

    Ha! Wish I had some answers on what's on it. I put it back in the Macbook and didn't load anything. The optical drive again acted like it was trying to load (or just randomly spinning/stopping the disc) and nothing would pop up. I checked the Finder and Disc Utility. It didn't show as if any disc was loaded. The eject didn't work. Hard holding the key did nothing and disc utility eject was grayed out. Eventually tipping it while it was making all it's noises allowed it to auto-eject pretty much. Could it just be a dummy disc used for testing?

    I doubt it. My guess would be that it's damaged.

    The disc although it wouldn't be a bad idea to check the drive with another disc. ;)

    does it look thicker than a normal one? wondering if its some sort of test disk to emulate a disk with multiple labels on it to check and see if it will get stuck

    never heard of such a thing though

    That could be possible. The disc is maybe just a little bit thicker. Not very noticeable, but I could say it's slightly thicker and heavier. I tried to take a picture of it. The disc on the left is the "thick disc" while the one on the right is a typical burnable disc.

    Yup, it looks just like a DualDisc. It makes sense that Apple would want to test them; last time I tried one (a few years ago) it almost got stuck.
