I can't seem to find this problem anywhere. I'm using Windows 7, 64 bit. I tried to burn an ISO image to a CD-R. Everything seemed to be going fine, finished burning, closed, then verified. Said it was successful. The CD looked like it had been burned. But it is only recognized as a blank disk. Tried it in two different computers, says 'blank disk' in both. I don't know if this is a problem with the program, Windows 7, the disk, the burner, or what. I burned a DVD (using a different program) the day before so I don't think it's Windows 7 or the burner. Any ideas on what the problem could be?
