[Debburn-devel] CD-Extra issues

[Ralf Baechle]

Hi,

I'm currently trying to produce the master of an audio CD with a few
extra bits in a ISO9660 fs in the 2nd section aka a CD-Extra.  This
is what I'm doing:

$ cdrdao write --driver generic-mmc:0x00000010 --multi cd/audio-cd.toc
$ wodim -msinfo
...
150,291114

$ mkisofs -o cd/mp3.iso -C 150,291114 -r -J cd/*.mp3
$ wodim cd/mp3.iso

The audio part of the resulting CD can be played or ripped as expected.
wodim -toc displays 18 entries + leadout, that is 17 audio tracks plus
the data track all as exected:

[...]
track:  15 lba:    229968 (   919872) 51:08:18 adr: 1 control: 0 mode: -1
track:  16 lba:    243412 (   973648) 54:07:37 adr: 1 control: 0 mode: -1
track:  17 lba:    270223 (  1080892) 60:04:73 adr: 1 control: 0 mode: -1
track:  18 lba:    291114 (  1164456) 64:43:39 adr: 1 control: 4 mode: 1
track:lout lba:    334629 (  1338516) 74:23:54 adr: 1 control: 4 mode: -1

But I can't seem to access the data part in any way.  dd if=/dev/sr0
returns an error without reading any data.  Curiously "cdrdao read-toc"
will display one track less that is the data track is missing.

I've tried many variants of this command sequence unsucessfully including
using wodim to burn the audio CD, too.  Nothing seems to work.

I'm using a "Optiarc DVD RW AD-7740H	Rev: 1.S0" drive in a Thinkpad btw.
Results with the "TSSTcorp DVD+-RW TS-H653B D300 PQ" drive in a Dell
desktop were slightly different but unsuccessful as well.

Any hints?

Thanks,

  Ralf
