you can clone it with dd.

assuming your flash drive is /dev/sbd and you are cloning it to a second flash drive, /dev/sdc

sudo dd if=/dev/sdb of=/dev/sdc bs=4096 conv=notrunc,noerror

You can save a compressed image to your harddrive

sudo dd if=/dev/sdb ibs=4096 conv=noerror | gzip > your_image.gz

Then use the image to make a new flash

dd if=your_image.gz | gunzip | dd of=/dev/sdc
