ImageUSB is a free utility which lets you write an image concurrently to multiple USB Flash Drives. Capable of creating exact bit-level copies of USB Flash Drive (UFDs), ImageUSB is an extremely effective tool for the mass duplication of UFDs. ImageUSB also supports writing of an ISO file byte by byte directly to an USB drive (*). ImageUSB can also be used to install OSFClone to a USB Drive for use with PassMark OSForensics™.

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 perform flawless mass duplications of all UFD images, including bootable UFDs.

imageUSB includes functionality to Zero a USB Flash Drive. This will replace the contents of the entire drive with 0s. Or alternatively to just Zero the MBR and/or GPT entries that exists on the drive. In addition, imageUSB has the ability to reformat even hard to format drives and reclaim any disk space that may be lost previously.

(*) CD ISO images use a different file systems compared to USB drives. So the direct imaging of ISO9660, Joliet or UDF file system, from a CD, to a USB drive, might not allow the USB drive to function in all operating systems. A reformat can recover the drive however. As of V1.5, imageUSB now supports extraction of ISO contents onto USB Drive.

Warning: Due to the forensic nature of image duplication by ImageUSB, please ensure that you select UFDs with a storage size similar to the image you wish to duplicate. For example, if a 2GB image is copied to an 8GB USB Flash Drive, the drive will only be able to use two out of the eight gigabytes of storage space. In this scenario, users will need to reformat the UFD in order to access the rest of the storage space.

Release 1.5.1000

WIN32 release 25 Oct 2019

-Support for extraction the contents of the ISO image.

EXPERIMENTAL - Software will try to detect if ISO image is bootable and if so write appropriate bootloader. As of release only booting through UEFI seems to be working. Tested with Windows 10 ISO, Linux (Porteus-5.0rc, Ubuntu-19.04 and Mint 19.2 ISO images). NOT ALL ISO IMAGES WILL WORK. This functionality is experimental and may be removed from software at any time.

Log moved into it's own Window to allow for larger visible USB Drive List.

Release 1.4.1003

WIN32 release 16 Apr 2019

-Fixed bug where formmatting as NTFS may cause imageUSB to crash.

Release 1.4.1000

WIN32 release 06 Nov 2018

-Extend Partition will add a new partition to fill remaining space when writing image smaller than drive if extending is not an option. New Partition will be formatted using NTFS. If more than one drive is selected in the write imaging processing. Due to likely disk signature collusion, drives may be placed offline by Windows. As such Extend or Add Partition may only work on first drive selected.

-Fixed bug where the Cancel Button on the Yes/No/Cancel Dialog Prompt before Imaging doesn't do anything. Should Now correctly cancel operation.

-Up total drive limit to 50 drives. All drives connected to computer (irregardless if they are USB drives) are counted toward this total. Note: We have never tested this many drives at once.
