After installing the latest DVDFab Build (11.0.6.4) I got a message from UHD Drive Tool stating that it detected that my drive was not UHD friendly because the firmware needed to be downgraded from 3.10 (which worked fine before the latest update) to 3.00. After I was unable to rip a UHD Disc with DVDFab I allowed the UHD Drive Tool to downgrade my firmware. I still can't rip any UHD Discs and now have firmware I probably shouldn't have installed. Ripping UHD discs worked perfectly before the latest DVDFab update.
