All users of growisofs (including users of frontends like k3b) get a spurious IO error at the end of writing a blu-ray BD-R medium.
This is a known bug that have been discussed on LINUX forums; there are different opinions, if this bug is harmless.
The proposed fix is very simple and seems to resolve the issue.
The solution is described at
and requires adding of 1 string of code to growisofs_mmc.cpp
This bug has already been reported in the bug 161694 that is marked as 'FIXED' but the problem still exists.
i'm the author of the proposed patch (and of xorriso).
PR 161694 is not about the same problem as this here.
(It rather looks like a run on DVD-R[W] or DVD+R where
growisofs reserved more blocks in the track than it
I'd be willing to help with diagnosing if further
information can be submitted. But it seems that the
PR was closed because no maintainer showed up.)
Have a nice day :)
