Thank you for your response. The error message is from Windows. I assume that Windows didn't recognize the blank disc that's why I got that message. I am using Mega Innovation. I have tried one other, which had LTH written on it. I also tried a Double Layered BD without luck. The drive recognizes the blank DVD's though, but for some reason doesn't recognize the blank BD's. Unfortunately, there are no driver updates available from Toshiba.
BTW, when I insert a blank BD the Roxio Burner reads it as DVD-RAM.
