Ubuntu - CD - Create ISO from CD

Using dd

dd if=/dev/cdrom of=~/cdrom_image.iso.

Examples:

DVD dev link: dd if=/dev/dvd of=isofile.iso
SATA/EIDE: dd if=/dev/hdc of=isofile.iso. View device name: “dmesg|grep DVDR” or “df”
SCSI: dd if=/dev/scd0 of=isofile.iso

This will capture boot information from a bootable CD or DVD. Also good for ripping a video DVD to an ISO image for duplication.

You must have permission to access the drive directly using dd. Mount permissions are not necessarily the same as dd permissions!

When creating an ISO file, the device must not be mounted. To unmount the cdrom device, use the umount command as follows:

umount /dev/cdrom

cat /dev/scd0 > cdrom_image.iso

NOTE: This will not pick up the MBR from a bootable installation CD or DVD.

Copy an existing CDROM into a new ISO-9660 image:

mkisofs -r -o /fully-qualified-file-name-of-iso-image.iso /dev/cdrom

NOTE: The CD must be mounted first.
