Damaged file straight out of camera

[Meshach_zm]

I was taking stills today at the motocross track and one of the many pictures I took turned out damaged. When I preview it in m y photo viewer, it looks alright then after a few seconds this pink false colour appears. This file is straight out of camera.
What could have gone wrong?
Please see attached.
