A free tool to test storage media for counterfeit space claims.

A review by Felix Cheng

H2testw is a free tool developed by Harald Boegeholz which can check your mass media devices for its actual size, as opposed to the advertised side.

The invention of this tool came about because of the sale of counterfeit SD cards and USB sticks which were not the actual claimed size.

With H2testw, you can write and read how much data the storage device is actually capable of holding. This can work with network drives, hard drives, SD cards and USB sticks.
