I have a Medion external HDD and it started fucking up today.

Basically I use it for storing tv shows and movies and when I open them now they are unresponsive and frames get dropped frequently. I tried running other files with no problem so its definitely the drive.

Question is if I attempted a back up now would I end up with a load of broken files and if so does anyone know how I can save everything? Its basically full of movies and shows and I'd hate to lose it all. Help!
