WinXp Nero7 burn fails Immediately after cashing of files

I have bu lots of BD-R's before and after. However, one fails with just ordinary files in directory. Every try to write fails BD-R immediately after cashing of files. Wrong files/directory? I have copy it to new place…

However, there is no problems to write it to BD-RE. I can make IMAGE.NRG too.

Bu fails immediately therefore no session closed, no disk closed. My question: can I repair failed BD. Can I make this BD appendable – repair with some loss of space in the begiing?
