Mount your cd.
df
The last line out from that command will be your cd.
It will give you a block count, divide that by 2 to get the number of 2048 
byte sectors on the cd.
umount  /dev/hdc
then:
	readcd dev=dev/hdc f=your.iso sectors=0-no_of_sectors

There is an option in k3b to burn from an iso, or just use cdrecord directly.

If you still have trouble it's possible that you have a faulty cd.
