If you have Service Code NS50 (this is stated on the drive's label), there have actually been several firmware updates since the drive's first release, the latest being 1.03 per LG's website. However, to use this drive to process 4K UHD with DVDFab, you will need firmware version 1.02 (you can downgrade if your drive has 1.03 via DVDFab's firmware downgrade tool). I have three WH14NS40 drives (two installed in PC's and one backup in case of failure). The two installed units have been in service since January, 2016 and I have never had any issues. I use Verbatim 25 GB media exclusively, and have not had even a single 'coaster'.
