My Dad has a CD-RW that he is trying to burn some work-related things on but we both can't figure this out. When he tries to put anything on it, it says the CD is full - but it's never been used. I put it into my computer (I'm at work right now so I only have Windows, unfortunately), and lo and behold - the CD appears to be empty when you open it as a folder, but by going through the Properties menu, is shows the capacity as being 100% full - at 0 bytes. In case it isn't obvious, I know little to nothing about burning CDs. Is this just a bad CD or are they supposed to be this way? Haha. Thanks!
