Hi Thomas; Thank you very much for getting back to me. So will try to answer your questions. Some of which may be delayed due to me having to run test. *- What is the vendor, model, revision of your drive. You may obtain it from the empty drive by* xorriso : NOTE : Disc status unsuitable for writing Drive current: -outdev '/dev/sr0' Media current: is not recognizable Media status : is not present Drive type : vendor 'ASUS' product 'BW-16D1HT' revision '3.10' *- Do you experience the problem with CD-R or CD-RW media ? If so:* * - What happens if you use a writable DVD medium instead ?* * - Does it help to blank the CD medium before using it with Brasero:* * xorriso -outdev /dev/sr0 -blank as_needed* Will Run these test shortly and get back to you with the results *- Do you experience the problem with other GUI programs like K3B or Xfburn ? - Do you experience the problem with a run of xorriso ? ISO="...path.to.your.iso.image.file..." xorriso -as cdrecord -v dev=/dev/sr0 blank=as_needed "$ISO"* Have not tried K3B or Xfburn. Did try Nero for Linux and had the same result as I did with Brasero. Thank you very much for the assistance. Talk shortly. On Fri, Mar 11, 2022 at 3:10 AM Thomas Schmitt
