The burner can not cope with the blanks from various manufacturers. So it is not possible for me only a CDROM with the blanks manufacturer Intenso create (Sales Representatives and on Media Markt). All CDs are defective after firing. This under Windows, and Linux with different burning programs. The contrast from Verbatim are good and do not have a committee with the device. Blanks Tevion (house brand of Aldi) also do not work. I know such behavior only from the early days of CD recording and thought that this would be long gone. Too bad, so the product is not recommended.
