--- Comment #4 from Gordon <gordoneki at web.de> ---
It appears your disc ran out of its actual capacity.

According to my experience, K3b or the optical drive overestimates the Blu-ray
capacity by around 280 MB.

What's worse: Because the session is unclosed, Windows can not read any files
from it. Only Linux can. This is not the fault of K3b, but Microsoft. The only
way to read files from an unclosed session on Windows is by using third-party
tools like IsoBuster. It has its own file browser.

Windows recognizes unclosed sessions on packet writing discs, but not on
unclosed sequentially burned discs.

When adding files, I recommend keeping a headroom of 280 MB at the end.

Even with overburning activated, the disc drive might refuse to go beyond a
certain point, and K3b can not overrule the disc drive.
