How to create an iso of a CD / DVD

With dd

dd if=/dev/cdrom of=myImage.iso bs=4096k
dd if=/dev/dvd of=myImage.iso bs=4096k

With readcd

aptitude install cdrecord
umount /media/cdrom0
readcd dev=/dev/dvd f=myImage.iso

If you want to have an idea of the speed of readcd, you can add "meshpoints=20 -factor" to your command line. It will output the speed each 5 percent of the process.
