So I’ve got myself a bluray burner with m-disc support and some m-disc bluray discs to use for long term cold storage of photos and videos. Now, my question is whether I have to collect enough data to fill the disc’s full capacity and write it all at once, or can I fill it partially, like half of it’s capacity, and then write more data to it at a later point?
