I'm attempting to burn my hard disc backups onto Blu-Ray discs. I'm using a Samsung portable BD writer model SE-506, about 2 years old, with TDK Blu-Ray discs. I used to be able to burn these without problems, but now about 2/3 of the discs I burn show errors on the verify phase.
I use K3B to burn them, and have replaced (adjective deleted) Wodim with CDRecord, so I'm not getting the end-of-burn I/O error message.
I'm running Debian Jessie with MATE.
I tried cleaning the lenses on the burner -- didn't help.
I did not find any information about this on the internet.
Do I need a new Blu-Ray burner? If so, any recommendations as to brand?
