After i burn a data disc and its busy writing the lead out i get this error message, "The drive reported an error: Sense Key=Hardware error Sense code=0x44, 0xD6
Internal Target Failure". Now I've deleted and installed it again and it does the same thing. What could it be???? And i how do fix it????

This generally indicates there is a serious issue with your recorder. At times doing a lens cleaning and using different brand of media might help.
