You can say that again! Just to tie up a few loose knots. I use mkisofs/cdrecord for the burning. If I use them like, say: mkisofs -l -J -T -relaxed-filenames -allow-lowercase \ -allow-multidot -R -o cd.iso /some/path cdrecord -v speed=4 dev=0,1,0 cd.iso Will I be making a single session CD? And will it be closed? From looking at the mkisofs man page the answer is yes to the first guestion. The second I don't know. Assume then in the previous a CD-RW disc. If I blank the disc with either cdrecord -v speed=4 dev=0,1,0 blank=all or cdrecord -v speed=4 dev=0,1,0 blank=fast and then re-record the exact same iso image as above: cdrecord -v speed=4 dev=0,1,0 cd.iso Once again, will the disc be single session and closed?
