USB Neutralizer is a bootloader/partition table killer designed to wipe just the minimum number of data blocks to render the USB Drive unusable by the operating system. Then without worrying for any malicious code, the USB can be safely plugged to your Operating System, reformatted and used for file storage.
USB Neutralizer is a "portable device" oriented and functional with the two dominant partitioning schemes the legacy Master Boot Record (MBR) and the "modern" GUID Partition Table (GPT). Logical Volume Manager (LVM), Zettabyte File System (ZFS) zpools, Btrfs subvolumes, Intel Rapid Storage Technology(Intel RST) are out of scope.
Every storage device requires a "partitioning scheme" to know how the available storage space is divided up. A partition structure defines how information is structured on the partition (File System), where partitions begin and end, and also the code that is used during startup if a partition is bootable. This information is required by the operating system to know which sectors belongs to each partition and how to interact (boot, mount) with them.
