Ripping UHD discs

[2luv4ever]

Want to make backup copies of the UHD/4K discs that I own. Currently using DVDFab 11. However, my 1 year old Dell desktop does not recognize the UHD/4K disc when I place it in my BD-RE optical drive (the drive does recognize "regular" blu-ray discs).
What do I need to do in order for desktop to recognize UHD discs so I can then rip them to backup copy? The properties of my optical drive are as follows: HL-DT-ST BD-RE BU40N, and it has the last driver.

2nd - you will need to use the downgrade tool to downgrade the firmware for your drive - https://forum.dvdfab.cn/forum/uhd-co...usb-connection
