Can't eject disk from Blu-ray burner BD-5850H in AW18 R1 (2013)

The only way I can remove the disk is to go into windows 8 and open My Computer and right click on the drive and click "eject". Pressing the eject key on the keyboard does not work (in BIOS too). Alienware OSD is installed. Windows 8.1 x64.

Any suggestions as to how I eject the disk without clicking eject?

My previous drive is DL-8A4SH. It eject correctly.
