If that doesnt work, you can take the optical drive apart very easily. Im not sure what computer you have, but follow our take apart guide for removing the optical drive. Once the drive is out, there are just a few screws on the top of the drive, and potentially the sides of the drive (depending on your model/mounting hardware), and the top of the drive pops right off. You can then take the small disk out, just be sure not to scratch the lens of the laser.
