Flash Drive not showing contents

I modded black ops zombie before using horizon and I stop for a few weeks. Few days ago I used me flash drive (had modded content and profiles on it) to update my Samsung smart Tv. I deleted files and downloaded the update. Since that when I plug in my flash drive it doesn’t show the profiles or anything. I re-download the profile and I switched flash drive, but it still doesn’t show the content. Can anyone help with this?

You need to re-configure your usb if you want items to show up in Horizon.

It doesn’t give me that option. I tired format it and still no option to configure it.

I remember this happened to a friend of mine. I suggest getting a new one, but from a different brand. My friend formatted it, and configured it, nothing worked.
