Ok I have a Toshiba M45 Series laptop. I recently had to reformat my hard drive because it wouldn't boot. So after I did that, about a week later, my fan stopped working and I think I'm gonna have to send it to a Toshiba repair place to get it fixed. NOW..my DVD burner wont burn CD's. It is supposed to burn both and now it will only burn DVDs not CDs. Ive tried 2 different brand of disks, Sony, and Memorex. When I burn DVDs Im using Memorex but when I use the same brand for CDs it wont burn. Ive tried slowing down the writing speed all the way down to 2x and it still wont work. I have a Matshita DVD-RAM UJ-831S. I'm hoping this doesnt need to be replaced too! Although I am under warrenty...! Anyone have any help!?
