Question : Any way to REVERSE an HD imaging?

I know a guy that used Norton Ghost (really, It's not me) to Ghost an image of a HD to a new HD, but apparently he got confused and reversed the Source and Target....so he essentially placed the image of the new HD (essentially NOTHING) onto the HD that has all of the data and obviously the Master Boot Record...

Anyone know of a way to reverse or recover from this mishap?

As hathehariken suggests but a different product.
