You shouldn't need to reinsert it. What I would do is check the card and the phone for the files though. Either through a file manager app. If the phone doesn't come with one you can download one. Or by connecting the phone to a computer via USB cord and search the phone and the card via the computer.
If the files were saved on either location, then they will be there. The only way they can be moved/removed is if you clear something (data, cache, reset, etc.).
