Cannot open SCSI driver. cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root. I suspect you are right about it being a multi-session disk. That sounds familiar. I just double checked, and I cannot find an option in my Windows software to force a single session disk. However, if the disk is multi-session, why can the 2.2.19 kernel could read it?
