I want to store in my hard disk some audio Cds, and I found an error using mkisofs tool making an iso image. The problem here is that mkisofs is not able to read an audio CD because it has not a valid file system as has a data CD/DVD.
I found the solution using cdrdao tool:
$ cdrdao read-cd -v 2 --device /dev/cdrom --read-raw --datafile cdaudio.bin cdaudio.toc
To write the image to an other CD run this command:
$ cdrdao write -v 2 --device /dev/cdrom --speed 4 --buffers 64 cdaudio.toc
