Has my burner gone bad?

Using DVDFab. It will copy fine to my hard drive, but it will not write to the media. It comes back with an error that it cannot read the media and asks me to put a compatible disc in the drive. I put a new blank disc in the drive and I get the same thing.
I have a LG GSA-6122D burner and I am using Verbatim media.
