CapacityTester – checks for fake USB flash drives

CapacityTester is a tool to test your new USB flash drive to find out if its full capacity can be used or if it’s fake.

The volume test fills the filesystem, verifying that all of it can be used. It’s slow, it takes hours.

The disk test overwrites the drive itself and is much faster (some GB/TB large USB drives can be checked in less than 10 minutes); but it’s somewhat experimental.

This is free and open source software. It runs under Linux and Windows.
