Check with the manufacturer of your laptop if there's a newer firmware for your burner. It seems the media you're trying to use isn't supported by your burner. Try with Verbatim or Taiyo Yuden blanks and it should work OK, especially the ones rated for 8x burning speed
Thx for a quick reply
I'll try that and post in the outcome...
P.S. thx for the blank hint,
Sincirely,
