I was using nero to transcode and burn an AVI movie to DVD and it was going to take a couple of hours so I left it running overnight.
When I woke up my computer was off and when I looked to see if the disc had burnt there was a circular scratch on the centre of the 4X TDK DVD-RW, which was brand new when I put it in.
Obviously it doesnt work , if I try to run it, it says
D:\ is not accessible,
Could you help at all as to what might have happened and how I can stop it from happening again?
