Should I be worried about my USB stick showing more space than advertised?

Asked by CuriousExplorer93
I recently bought a USB stick that claims to have 256GB of storage, but when I checked it, it shows 461GB instead. Should I be concerned about this discrepancy, or is it likely just a mix-up by the manufacturer? I lean towards thinking it's a mistake, but I want to be careful.

461GB seems like a random number to me, which raises a red flag. It could be a fake USB stick. You might want to try copying a lot of files onto it to see if it can actually hold them all. Remember to check if those files work afterwards!

FileChecker18: Definitely check the files after copying. Sometimes they might appear to work but could be corrupted.

Honestly, it sounds like you might have bought a fake. These things happen more often than you'd think.

It would help to know the brand and where you got it from. It sounds pretty sketchy without more details.

To get a better idea of the actual capacity, you should run a tool like Validirve or H2testw. They can help verify how much space the USB stick truly has.

I wouldn't completely trust that USB stick. Can you tell us the brand? That might give us some insight into its reliability.
