Double slit experiment shows a wave pattern when "which path" info is unknown.
When which path the photon took is known, a particle pattern exists.
If the which path information is collected and stored, say, on a harddrive, but nobody looks at the data, then that info is still unknown and a wave pattern exists? Or does the data need to be destroyed from the drive to show a wave pattern?
