WD My passport : message states to format; drive already has video on it

I’ve tried everything. Our lcoal cable studio uploaded film for me to review. I plugged My Passport Ultra to my laptop. The drive is visible but the message states" drive is not formatted."  Very frustrating.

Hi, it is possible that some files are corrupted, usually the message that shows up request for you to format the hard drive. If you can access the files, do a backup and then format it. If the files are not accessible, you can use a data recovery program and then format the drive, using Google you can find several options.
