A couple things about the XB1: it was not designed to be stood on its side like the XB360. Doing so could potentially damage the drive. Second, and there should be a label on the console stating this, but the console should not be moved when a disc is spinning in the drive.
If someone does either of the two, it's not "defective" it's user negligence if a disc gets eaten or the optical drive goes out of alignment.
