Burn multisession CDs using cdrtools (cmdline)

This time in cookbook style:

  • Get the current CD's multi-session info by

    cdrecord -msinfo

    • You got a pair of numbers representing the start and end blocks of the latest session. We'll need them for the next step.
  • Use mkisofs along with the next flags to create the image:
    • -M /dev/cdrw: path of your cd/dvd writer device
    • -C start block,end block: use the pair of numbers you got above, but you must increase the start block by 1!
      i.e. if cdrecord -msinfo gives "11231,44323", you should use something like that:

      mkisofs -J -R -o /tmp/myimg.iso -M /dev/cdrw -C 11232,44323

      Why the +1? I'm not sure! Common docs don't mention it!

  • Burn the new image with

    cdrecord -tao -multi /tmp/myimg.iso
