4K UHD Blu-ray disc is a new type of Blu-ray disc that is not compatible with old drives (made before the second half of 2015), just like BD XL didn't work with non XL drives
In 2015, some LG drives got a new hardware design, a new front (bezel) and started to "see" the content of UHD discs: those were WH16NS40 and BH16NS40, with SVC NS50 on the label. They're good enough to work with DVDFab, called them UHD friendly. Because Asus is re-badging LG drives, they also got the update.So new drives of those older models are compatible with DVDFab (see the list below). To buy safer, just look outside North America and find the same drive sold as BH16NS55.
The best of this batch is the USB 3.0 drive called BE16NU50, recommended
Most of the friendly drives have a bug: once the UHD disc is in, if it's not used for more than 2 minutes, the drive goes in standby mode and then it will not read the disc anymore.The easiest is to eject and re-load the disc. There will be a workaround for it in the near future.
Somewhere in 2016, LG released some official UHD drives, starting with BU40N and BU50N. Buffalo also released a re-badged BU40N in Japan. Those official UHD drives are very stable and recommended. Finally, LG released their first internal official UHD drive in US, the WH16NS60, which is also recommmended.
Pioneer drives, released in early 2017 are not supported at the moment, but may be in the future.
Final note: do not update your drive to any new firmware LG or Pioneer may release. If you do, your drive may not work with DVDFab anymore. Always check this page, before a firmware update and as long as your drive works with DVDFab, you simply don't need to update the firmware.
