Sony wasted several gigs of the very small (32g to 120g) and very expensive ssds of the time with 2 copies of a Spider Man 3 movie pre-loaded onto several different laptops. One copy in the normal installed fs, another copy in the recovery partition.

And you couldn't even watch the movie unless you also paid to unlock it.

You could delete the normal copy if you even knew it was there and then also used a disk usage util to FIND the actual file. But you couldn't do anything about the copy in the recovery image except delete the recovery partition and basically wipe & repartition the drive and do your own fresh install.
