WHEN I BACK-UP SELF BOOTABLES I GET BUFFER UNDERRUN OR UNREADABLE DATA ON MY DC.

I HAVE A TEAC W54E AND USE NERO OR BLINDREAD AND BLINDWRITE (WHICH I DONT KNOW HOW TO USE PROPERLY,I HAVEN'T HAD ANYTHING ELIGABLE FROM IT SINCE I BOUGHT IT)BUT WHEN I USE THE WIZARD ON NERO WITH SELF BOOTABLES I EITHER GET BUFFER UNDERRUN OR A BURNED DISC THAT THE DC DOESN'T RECOGNISE PLEASE HELP!
