HL-DT-ST DVDRAM GSA-T40N ATA Device fails to burn

Hi! I have ASUS Notebook X59SR with LG HL-DT-ST DVDRAM GSA-T40N ATA Device. It recorded well many CDs and DVDs. I was using Ashampoo Burning Studio. But a week ago, when a was burning a DVD-ISO with Ashampoo it failed to burn. I tried two more times with different types of DVDs but the burning failed again. Then I tried to update the firmware of the DVD/CD burner and Windows tells that the latest driver is already installed. I serched the LG Support website for firmware but there isn't any for this device. My current firmware is JR03. I tried reinstalling Ashampoo but there was no success. I also tried to burn with Nero 8 but it failed again. I'm always using Verbatim DVD-R. I'm showing you Nero's error log
