Broken USB stick

Hello, I have a problem with a Corsair Voyager USB 3.0 USB stick (16GB).
I think I managed to somehow break its partition table and quite possibly even introduce other problems as well. On Windows, it is recognised as a data carrier of some sorts, but trying a simple format is out of the question, because "there is no disc present in this station". When I try to use it on Linux it doesn't mount it at all (probably because it can't see any "disc" in it either). My OSses only seem to be able to tell that something has been connected through USB, but it doesn't seem to be able to look inside of it.
I would rather be able to use it again, but the way things currently are I am completely at a loss. It still worked perfectly yesterday, and I didn't do anything dramatic, and I really just think some write went wrong, and that it is not a hardwarematic problem. I am at a loss concerning how to fix it, though...
