That disc is the result of a failed burn from another burn attempt and it got damaged in the process, so you'll have to try a new one. But first, contact the laptop manufacturer and check if there's a newer firmware available for your burner. Alternatively you could get a normal-sized burner in an external enclosure, as they're reasonably unexpensive and will make better quality burns
Thank you for the very prompt reply!
Apparently I have the latest firmware for my Vaio but that was from doing an internet search to find out, not by contacting Sony.
Changing the disc got the process through that hurdle but it then failed at this point: Failed to set L0 Data Zone Capacity!
Any ideas?
