"Hidden" Flash Drive?

[Jingybell]

I'm currently making a Powerpoint document at school on a PC and I am finishing it up at home on my Mac. I plugged in my flash drive and opened the Powerpoint normally and later, I accidentally hit something along the lines of "Hide Disc/Drive" and now my Flash Drive doesn't show up in Finder. I can search for the docs that are on it and my Mac tells me that I didn't safely eject it when I pull it out, so it is definitely recognized, but not displayed.

So, how can I get it to show up in Finder again?

Does it show up in Disc Utility? If so, try highlighting it and click on mount in the top bar.
