ANSWER: The software inside the burner that drives the hardware. It calculates CRCs and writes the error control information if you leave it to the burner. The external software (like CloneCD) sends commands to the hardware that are interpreted by the firmware.

ANSWER: Probably. The kry in your situation to avoiding buffer under-run is to do three things:
1 Keep your hard disk defragged otherwise it can't supply data fast enough
2 Put your burner on a different IDE channel from the HDD otherwise they compete
3 Don't run other programs at the same time that use the HHD

You probably knew those pieces of advice from hard experience.
