The most notorious use of the PS2251-07 MPTool is combating the "fake flash" epidemic. Unscrupulous sellers often program controllers to report a capacity of 1TB to the operating system, while the actual memory chip is only 16GB. Once you write past that 16GB limit, the data vanishes into a black hole. The MPTool is the only way to "low-level format" these drives, stripping away the lie and forcing the controller to report the honest, physical truth—usually bricking the drive in the process or salvaging a tiny, honest fraction of its claimed size.
