My USB drive is acting up—is my wedding footage gone forever?

Hi everyone,I tried to copy some old videos from a thumb drive I found in my drawer, but my Mac keeps telling me that it’s a corrupted file and cannot be read. These are clips from my brother's wedding, so they are incredibly sentimental, and I’m terrified that the hardware has failed.

My neighbor says sometimes the "Table of Contents" on the drive gets messy, but the data is still there. How do I recover a corrupted file?Thanks in advance.
