How do I format an SD card to a smaller capacity?

So I’ve got this 64 GB SD card that turns out to be a total scam—it’s actually just an 8 GB chip masquerading as the big capacity it claims to be... I really want to just stop fighting it and actually use those legitimate 8 GB before I lose my mind, but I need to figure out what the actual, honest-to-god usable space is first.
I’ve already messed around with standard formatting, poked through Disk Management, and even tried a few different partition managers, but nothing is sticking... I can't seem to find a way to force it to behave. Any ideas on how to fix this mess? Thanks in advance.
