I run opensuse 10.3 with k3b 1.0.4 and wodim 1.1.6. The CD burner never finished writing data before finalizing the disk. Attached below is the message I obtained from k3b. I have wasted a whole pile of CDs already. Could anyone kindly point out what is wrong with my system and how to fix it?

Thank you very much.
