I am asking because I experienced similar problem on TDK disks; in my case the speed limit was x8. The writer managed to successfully write some disks while failing on others. After I have limited speed to x4, all the disks were written successfully. It looks like when I go maximum, the disk quality is in question. Have you tried setting the speed limit below the maximum?
