How to hide Data on a drive?

Okay this might be the most paranoid you've heard in a while, but hear me out:


Most of you maybe heared about those scam USB drives you can buy from China from really cheap which tell you its 512Gb but actually is only 8Gb or something like that. As far as I understand, this is done because the controller chip tells the PC "Im a 512Gb one" but its not true.


Soooo my idea is to use something like this …
