Attaching logs for ./growisofs -Z /dev/dvdrw=dvd.iso (nodao.log) ./growisofs -use-the-force-luke=dao -Z /dev/dvdrw=dvd.iso (dao.log) The difference in the actual commands sent seems to be stark. Is there a way to place a DVD burner into simulation mode as with CD recording so as to test the comma

Hi, attached is a patch which enables SCSI logging to stderr in dvd+rw-tools. It is based on dvd+rw-tools-7.1.tar.gz (MD5 8acb3c885c87f6838704a0025e435871). There is no run-time control for this feature yet. Define or undefine macro Libburnish_scsi_log_to_stderR and run "make" to enable or disabl

Hi, this time the layer break position was not set by growisofs. Now i wonder what is the difference between the commands sent by growisofs and libburn underneath xorriso. Looking at the source code of growisofs it seems that no command RESERVE TRACK is sent for DVD+R DL. libburn sends it if it d

This is terrible. How can growisofs mess this up so badly? I didn't even eject the disc and immediately can burn the image with xorrecord with no problems. $ growisofs -Z /dev/dvdrw=dvd.iso Executing 'builtin_dd if=dvd.iso of=/dev/dvdrw obs=32k seek=0' /dev/dvdrw: "Current Write Speed" is 1.6x13

Hi, the problem looks like it is triggered by growisofs' habit to explicitely set the layer break position. See its message /dev/dvdrw: splitting layers at 2009552 blocks and its error message 4115562496/8231090176 (50.0%) @0.0x, remaining 16:15 RBU 100.0% UBU 100.0% :-[ WRITE@LBA=1ea9d0h f

I also tried Pioneer BDR-205 Blu-ray recorder, firmware 1.12. growisofs can record any blank DL DVD with no problem. xorriso can record DL DVD on either drive. So, the problem seems isolated to growisofs and some alignment peculiarity with the firmware of this DS8A1H drive. -- You received thi
