So if I sell my laptop that still has some photos on it, the buyer would own the copyright over those photos because they own the laptop? If I deleted the photos from the laptop, but they used a recovery tool to restore them from the disk, would they still own the copyright then? What if I have the same photo on two different USB drives, and I sell those to two different people, who owns the copyright then? That doesn’t seem right. Copyright is not generally attached to a physical medium. You don’t lose copyright by losing ownership of the physical medium that holds a copy of the photos/source code/etc.
