You need sfdisk and losetup.
sfdisk -l -uS disk_image.raw
# look for the start sector of the partition, e.g. 2
mount -o loop,offset=$((2 * 512)) disk_image.raw /mnt
#mount the partition to /mnt (replace 2 with the output from sfdisk)
You could of course also use kpartx to create special device files for the partitions.

ddrecue is better than dd, dd_rescue or dd_rhelp if you want to (try to) backup what's possible from a broken (hard or compact) disc. It creates a log file and which lets you continue interrupted backups. If you try to backup a broken cd or dvd it might help to use different dvd drives to try to read the disc.
Don't let it run over night or you might end up with an exhausted dvd drive that doesn't really want to read anything any longer.

It's one really easy command, if you know what it is ;)
sudo dd if=/dev/zero of=/dev/XXX bs=446 count=1
That helps you to remove any boot sector from that device, e.g. sda. But make sure you've got a boot sector somewhere! I can recommed installing grub to a USB stick for backup purposes.

If you've got a large USB stick, there's a high chance you will have some space left for
installing a current Knoppix on it. That way you can save a few CD-Rs as you need not write a new CD when a new Knoppix comes out.

The German "Stiftung Warentest" tested various kinds of recordable CDs and DVDs. The results show that TDK is a recommendable brand for recordable CDs and Verbatim is good at making recordable DVDs.
The
test can results can be read for free online. If you don't speak German, check out the
google translation.
