I have never had problems with my negs but anything that comes from an outside lab inevitably sports scratches for some reason. I don't even let labs cut and sleeve my films these days. Also as Bill mentioned certain light sources make scratches more apparent. My previous scanner used cold cathode illumination which was condensed but still relatively soft whereas my current nikon scanner uses LED for illumination. The light is mixed by firing the LEDs into both ends of a glass rod which has a white reflective area along one edge so it remains somewhat directional. The long and short of it is that the LED system really tends to make the smallest of scratches very visible in the scan, the cold cathode illumination wasn't near as bad.
