I used to have trouble burning CDs until I discovered the instructions
at http://www.troubleshooters.com/linux/coasterless.htm. Your mileage
may vary, but now I always use the following command and don't have any
problems:
cdrecord dev=0,0,0 speed=16 padsize=63s -pad -v -eject -data
/tmp/name.iso
Note: to figure out the device, use cdrecord -s -scanbus
Note: use a slower speed, if you have a slower CD writer
