About 50% of the time a "verify" of a blu-ray data disk, I will get this error "error reading sector 268,435,456" on the startup of the verify process. This is just after the switch from recording to reading.

The verify process stops
the disk is ejected from the USB/blu-ray drive.


I am then forced to verify the long way ( extract all the files from the blu-ray, and then diff ). This long way shows no errors in making the blu-ray.

The debug log file is useless , as it shows nothing after the mkisofs.
I dont even see this error in the log file. Maybe i need a verbose setting?

This indicates that either the utility K3b is using does not support Blu-Ray size disks, or the way K3b is interacting with it is causing this support to not work.
