USB Image tool – There are two modes to use within this utility:

• Device Mode
• Volume Mode

Here is a quote from the FAQ page which outlines the difference between those two modes:

Q: What is the difference between device and volume mode?

In contrast to the volume mode, the device mode copies the whole USB device, including boot sector. So if you want to make a backup of a bootable USB device, or you have created a flash drive with more than one partition, you should use the device mode. The volume mode processes the first volume on an USB flash drive. Windows currently limits removable USB flash drives to only one volume. As long as the partition information on the flash drive doesn’t change and it is not a bootable device, it is ok to use the volume mode.

The tool is free, but you can donate few bucks to the author – Alexander Beug.
