Yes, memory cards and USB sticks with hacked firmware to report their size as larger than the flash actually present are disappointingly common. The flash typically "loops" at every multiple of the actual size, resulting in filesystem and data corruption.

TL;DR if the price looks too good to be true, it probably is. Buy from official retailers if you want a fighting chance of getting working goods.

If you suspect that you have a fake item, or want to check that your
recent purchase is not a fake (before sending your precious data to
the device).

You can use H2testw (Windows) or F3 (linux) to check the actual
capacity of the flash memory devices.

SDHC ive had no problems on Panda with 16 / 32GB, micro;s pretty much the
same.

USB sticks ( USB 3 ) go to 1GB but around a grand for any decent brand.
