Tried formatting with rufus? that should fix it

Fixed it thanks. Any idea why that happens?

Flash drive or external hdd?

Flash.

If it works on your PC then reformat with Rufus like mentioned, if it doesn't work on PC then it's corrupt or damaged, they flex frequently n break easily

It worked I wonder why though. What does Rufus do differently then just formatting it through Windows?

It fixes bad sectors
