Closing Blu-Ray Data Disks in Creator NXT 3 Sales Questions Posted April 17, 2015 · Report reply Presently I am running NXT and considering upgrading to NXT 3. One of the problems I have with NXT is that if I burn a Blu-ray DATA disk, it writes to the disk OK and all the data is readable but I cannot close the disk no matter what options I select prior to burning. I have not tried to write anything else to the Blu-ray disks so I don't know if it affects all Blu-ray writing operations or just data. This creates a potential data integrity problem. Is this Blu-ray data disk closure problem fixed in NXT 3?
