blu ray pseudo-overwrite

2016-03-29 Thread Jan Gregor
Hello, I found that two files on formatted bd-r media cannot be read. Since few hundred megabytes are left on medium and spare area is also not full, is it possible to correct the files via pseudo-overwrite or new session ? First method seems to me more natural, same is used when data written to
