Make copy of knoppix cd?

[rickenbacherus]

I got the knoppix cd and it works great. I'd like to make a backup copy but don't know how. One would think that this could be done with k3b but I can't seem to make it work. K3b fails at the start of the copy process. Anyone know how I can do this?

Hmmm- I think you are using an elephant gun to kill a mouse. Presuming that you can boot Linux from hdd then just use dd or cat like so:

dd if=/dev/scd0 of=/home/user/Knoppix.iso

or

cat /dev/scd0 > /home/user/Knoppix.iso

Phooey on the GUI.

If you're trying to copy the cd while booted to it then I think that won't work.
