I purchased an external disk writer from ASUS. This one: https://www.asus.com/Commercial-Data-Storage/SDRW08D2SU/
And M-Disks from Verbatim, these ones: https://www.amazon.co.uk/gp/product/B01E0CUU1C/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
But inserting the M-Disk into the disk writer, neither Brasero nor K3b seems to recognize the medium. It works if I insert a regular CD, and it mounts it, and I can browse the content. But a blank M-Disk is not recognized as a medium that I can do anything with. I obviously am looking to burn content to the M-disk.
Does anyone have experience burning M-Disks with Ubuntu? In which case, what works?
