Anyway to get my old thumb drive back to how it was?

[Andalusian]

I kind of regret using my best one, when I should have probably used an inexpensive one, but the upside at least is that I have a reliable drive to do memtest.

So any methods?

What kind of thumb drive? What happened to it? If you tried to format it with Windows and now it shows up as very small,
then use Rufus. You were trying Linux? Been there.
