Running kubuntu 17.04 on machine that includes an LG WH16NS40 with firmware version 1.02 (apparently latest version).

I'm attempting to burn a 12.0 GB ISO image onto either 25 GB or 50 GB BD-R disks in the above Blu-Ray drive. K3b in the Burn Image dialog reports the disk as being empty and having 23.3 GiB free space (for a 25 GB BD-R), and thus allows me to start the burn. Yet, when I attempt to burn the BD-R, K3b reports:

Found medium: Empty BD-R medium
Please insert an empty medium of size 12.0 GiB or larger into drive
HL-DT-ST BD-RE WH16NS40 (/dev/sr1)

K3b and Gnome Disk Utility correctly detect this drive as a Blu-Ray drive. The odd thing is that Gnome Disk Utility reports the volume size as 2.0 KB; I would have expected it to show 23.3 or 25 GB for this disk.

I get similar results from Brasero.

Does anyone know what's up? Do I need to supply more information in order to figure this out?

The K3B refusal and message is a known bug:

solved by the non-Debug parts of

It simply never accepted BD media for the job of image writing. Data composition + burning worked with BD.

For diagnosing the problem with Basero one would need more tangible information.

Gnome Disk Utility might show the readable size of the blank medium (but then showing 2 KB too many).

The kernel messages are normal with blank media. (Not enough brain to refrain from trying to read it.)

If you are willing to use the shell command line, try this for burning:

xorriso -as cdrecord -v dev=/dev/sr1 fs=32m -eject /...path.../my_image.iso

with your ISO image file path instead of /...path.../my_image.iso .
