Mystery Hardware Error

[David M. Patronis]

When I burn a data cd using the burncd utility, I get this error at the 
end of the session:

acd0: FAILURE-READ_BIG HARDWARE ERROR asc=0x3e ascq=0x2

When I burn a second disc, there is no error message, and I've yet to 
have a bad burn. In fact I'm getting quality superior to that I was able 
to produce using Windows or Linux. What does the error mean, should I be 
concerned, and if so, what steps should I take to resolve the problem?
