[ Solved ]
Issue GH22NS50 not been seen by CDBurnerXP on a Ausus Crossair Formula III running Windows 7 64bit, and a AMD Phenom II x4 955 cpu.
On the above motherboard Sata ports 1-6 were set to AHCI mode, to get the GH22Ns50 to work correctly you need the sata port in IDE mode.
Connect the GH22NS50 to Sata port 5 and in the BIOS set ports 5 & 6 to IDE,leaveing Sata ports 1 - 4 in AHCI mode. Reboot and windows 7 will install new hardware drivers and your GH22NS50 will work work CDBurnerXP.
Hope this helps someone.
