Of course, by that point it might be just easier to simply return it, especially if it probably has abysmally slow write speed (might take a week to "fill" the imaginary capacity). Unless these counterfeits have gotten much more sophisticated recently (like stream data compression on the fly), it works pretty well.

a USB stick or counterfeit camera card might show as "64GB" to the system and allow "writing" up to 64GB of data, but if only the first 1GB of that data is readable without an error, it's simply a cheap 1GB chip with a hacked controller).

Basically, it just writes sequential data as long as it can (until the disk says "full"), and then reads them back and reports when it gets an error (e.g.

You might want to check the F3 utility to get the real capacity of the drive, as I mentioned above.
