Here's what's happening, and why...

First of all, Sony is saying they can do this, because they are not calling them CDs. (It is NOT a standard CD format) The CD logo, on the disc and cover is replaced with the phrase "Not playable on PC or Mac". The first track on the disc is a data track that forces the player into an infinite loop. Since it won't stop spinning, it won't let you eject. If you reboot to stop it, it won't let the operating system come up.
Most can bypass this by holding-in the eject button during start-up. For many new PCs, and ALL Macs, there is no eject button on the drive itself. Mine is controlled by keyboard or software. So for those without a way to manual interrupt the spin, it locks up the computer, and in my case (a DVD burner) will completely disable the drive.
