Duplicating a CD with DDWritten by Mark Sanborn: Apr 8, 2008
Want to make an exact copy of a CD without installing k3b or some other burning software? You can do it in Linux/Freebsd with one line of code using dd. The nice thing about dd is that it will make a disk level duplicate of the CD. It should be a 100% exact copy.
Just replace the ‘/dev/hdc’ with your cdrom device and change ‘/path/toSave/CopyOfCD.iso’ to the place you want to store it.
$ dd if=/dev/hdc of=/path/toSave/CopyOfCD.iso bs=2048 conv=sync,notrunc
To mount it and list the contents:
`# mkdir /mnt/myCD
mount -o loop /home/mark/CopyOfCD.iso /mnt/myCD
$ CD /mnt/myCD $ ls`
You can burn with this command:
cdrecord -dao -speed=CHANGEME -dev=CHANGEME CopyOfCD.iso
