Try to do another test with cd-dvd speed.
Insert a disc on the drive, then select the "create disc" tab. Select a burning speed (I suggest 12x as a first test), then press the start button. This will burn a disc with some random binary data, so the test will cause the waste of a disc, but it's a necessary sacrifice to test the drive
After completing the test, can you post the picture here? You can save the image clicking on the little floppy button on the high-right corner, and save the picture as PNG file.
