I am seeing this in 13.10, on a Lenovo L430.
- There is no CD in the drive. The drive is empty.
- The physical switch on the CD-ROM drive does nothing.
- The door works fine after reboot. It gets locked after ejecting 1 CD.
- This happens when ejecting using Nautilus, and also when ejecting using Unity 
dock right-click-eject.

$ sudo eject -v
