I had to format my hard drive 3 days ago due to my brother getting his hands on my laptop. I copied a CD for the car no problems after putting everything back on the laptop after I formatted it. Then today I went to copy a Data DVD using Nero 7.0 and it doesn’t recognise the blank disk at all. No burning program will. Realplayer, Sonic etc. What could be wrong with this as I really need to burn this disc for college tomorrow. It says please insert a blank disc. I have updated all the drivers, the flash firmware with still no luck. It’s a Dell 5160 Notebook. Please any help is much appreciated.
