Or alternatively to just Zero the MBR and/or GPT entries that exists on the drive. This will replace the contents of the entire drive with 0s. ImageUSB includes functionality to Zero a USB Flash Drive. ImageUSB can perform flawless mass duplications of all UFD images, including bootable UFDs. Unlike other USB duplication tools, ImageUSB can preserve all unused and slack space during the cloning process, including the Master Boot Record (MBR). ImageUSB can also be used to install OSFClone to a USB Drive for use with PassMark OSForensics™. ImageUSB also supports writing of an ISO file byte by byte directly to an USB drive (*). Capable of creating exact bit-level copies of USB Flash Drive (UFDs), ImageUSB is an extremely effective tool for the mass duplication of UFDs.
