ImageUSB

Freeware

Quickly create an image of a flash drive and everything that connects to USB, and save it to your hard drive.
The image can be recorded on any number of new USB-drives (UFDs).
There is validation of the recorded data.
The program also supports byte-writing ISO images to USB flash drives.

When recording on media, the program, in addition to actual data, can also record unused free space, including Master Boot Record (MBR).
