(or generally speaking, how to create an exact copy of any multitrack CD)

1. copy the cd to an image file

# cdrdao read-cd --read-raw --device /dev/hdc --driver generic-mmc-raw --datafile cd.bin cd.toc

2. burn the image to a cd

# cdrdao write --speed 64 --device /dev/hdc --driver generic-mmc --eject cd.toc

Using cdrdao ("disk-at-once") is imho the best solution to copy a CD, because you get an exact copy of the whole disk, not just a copy of each track. => This preserves for instance the delay between tracks on an audio CD.
