How to permanently clear and erase all data on USB without recovery

If you search online and you’ll find that most deleted or formatted files can be restored from USB or other storage devices.
Is there a way that can help erase and clear all data on USB or USB external hard drive without a recovery possibility? Sure!

Mostly, a low-level format can do. 
But we do not suggest you take this method.

Low-level format can erase all existing data, but also may result in storage device logical structure destroyed.
That is to say that when you commit a low-level format on USB, the existing or deleted data indeed will be removed. But the device will also corrupt, failing to function again.

Any other method can do this job? EaseUS free partition manager software - Partition Master Free Edition can do.
