Start by updating the firmware in the drive... YL02 is pretty old. (Granted the latest firmware is still 2008.... :) ). YL05 solved a lot of problems with media compatibility... Enter the model number (GGW-H20L) here: See if that solves the problem... If it's all Verbatim media that's causing the problem, this might solve it... If it still fails, but burns other discs okay, you might just have to stick with other media. The drive is kind of old (still have mine though!), and it will start to fail eventually... Rik
