Check this before throwing away unused USB drives, file deletion is not enough

Deleting files alone is not enough when disposing of or recycling an old USB drive because deleted data can be recovered, requiring additional steps such as formatting. If a computer cannot recognize the drive, physical destruction can still reduce the risk of data leaks. For drives to be reused, a full format is presented as safer than a quick format because it overwrites existing data. For drives not to be reused, physical destruction is described as the most certain option.
