Here's an easy (and very cool) way to make a copy.

1. Boot into the original Knoppix disc.

2. Open a shell and type cdrecord -scanbus

You should get output something like this:

Cdrecord 1.10 (i686-pc-linux-gnu) Copyright (C) 1995-2001 Jrg Schilling
Linux sg driver version: 3.1.24
Using libscg version 'schily-0.5'
scsibus0:

0,3,0 3) *

You need to take the bus that your burner is listed on and use that info to burn your new CD.

For example I would do it like this:

cdrecord -v dev=0,0,0 speed=4 -isosize /dev/scd0

Just plug in your info into dev=x,x,x

Hit return and your new CD will be copied.

A couple of caveats: You can adjust the speed option as high as you want, but just make sure that you don't make it faster than your cd reader can read. Othewise you'll end up with a coaster. You may want to use a CD-RW if you think you will be setting it too high.

I did this on a box with 256 MB of ram. I wouldn't suggest it with anything less than 128.

If you end up with a bad CD, you can blank the CD-RW and start again like this.

cdrecord blank=fast dev=0,0,0

Again plug in your device into the formula above.

Give it a try and see how it goes. I have copied CD's successfully this way.

You can also use k3b to do all this if you want to experiment, but i find the command line much faster.
