Easy,
First say cdrecord --scanbus and be sure your burning device is 0,0,0 (or see what it is) then as root go to the directory where the iso you want to burn is located and say :
#cdrecord dev=0,0,0 speed=12 my.iso

If you want to trun your knoppix cd (or any cd) back into an iso on the hard drive just (with the cd in your drive but the drive unmounted) say :
#cat /dev/cdrom > my.iso

cat will copy it to an iso using the raw format just like clonecd

Yup, I've tried that. However, 'cdrecord -scanbus' does not give the speed (ie: speed=12). How do I get that info?

Try dmesg | grep sr0 this should give you a line describing the first scsi device with the speed(s) in it use sr1 if it is the second cdrom in the system. You could also use scsi to get every line with scsi in it from the boot messages also I have found it helpful to look at the drive it usually has the speed(s) on the tray.

my cdburner is 48X but I wont burn an os over 12x and assumed his was at least that fast...sorry.

tech@tech2k:~$ dmesg | grep sr0
Attached scsi CD-ROM sr0 at scsi0, channel 0, id 0, lun 0
sr0: scsi3-mmc drive: 48x/48x writer cd/rw xa/form2 cdda tray
tech@tech2k:~$

ohhh..i like that command....thanks Stephen

OK, I used dmesg | grep sr0 and got "...32x/32x cd/rw..." How fast should I set the burn then?

TIA,

How fast should I set the burn then?

I never bother to set the burn speed! I think cdrecord interrogates the disk and drive at arrives at something suitably conservative.

But (it says here)

If your drive has problems with speed=2 or speed=4, you should try speed=0.

So your line would be (something like):

cdrecord dev=0,0,0 -v speed=0 /path/to/.iso

given that cdrecord -scanbus returns 0,0,0 of course.

But, as I say, I'd be shocked, horrified and disappointed if just ommiting the speed line didn't work.

[A. Jorge Garcia]

Sounds good! Now, by 0,0,0 you mean: channel 0, id 0, lun 0, right? That's what I got.

I think so. This should be the output of

cdrecord -scanbus

if you only have one CDwriter (but best to check). You'll get something like:
