have a 64GB flash drive that used to work and after an update, now doesn't show up in finder

I have a 64GB flash drive that worked just fine and Finder would show it when I would insert it, well it seems that after I updated my mac it now doesn't recognize or show the flash drive. I am unsure if the update did something but like I said it worked previously to update and it works on other windows based computers. So is there a way I can fix this?
