Hi everyone. I've come up against a strange problem I never had before. But then I've never used DVD-R before either (a friend gave me a pile of them), I usually use +RW. I filled 4 DVD-R discs with data a month or so ago, and today when I tried to view the data, Windows says it's a blank disc. It also says there are 0 bytes left of free space on the discs. So it seems the data is still there but not seen by the computer. Has anyone seen this before, and how do I fix it? Thanks in advance for any help you can give.
