For some reason, FCP was not recognizing the media on the drive. It renames the clips upon importing them as the date/time the clip was created.
Anyway, Apple Tech suggested I connect the original cards from the camera. Fortunately, I had not reformatted them! I imported one card, and it fixed the missing camera file issue. What’s interesting to note is that it not only referenced to those clips on that card but also with the clips from all other cards, which makes me believe that the software had a glitch in its database.
I hope this post will help any others having this issue.
