How do I make a physical copy/backup of a nBox flash disk?

All you have to do is to use a tool that allows you to do a physical copy of a device. Copying a nbox flash disk is similar to copying a standard disk device. On Linux you should use the dd tool whereas on Windows you can use WinDD. The procedure is pretty simple:

1. identify the device name you want to copy. Please note that you must copy the whole nbox disk and not just a partition, so please select the disk device (e.g. /dev/sdb) and not a partition (e.g. /dev/sdb1).
2. using dd you can create a file to save on your hard disk that contains the image of your flash disk. On windows you do this using the graphical interface, whereas on Linux you it as follows dd if=/dev/sda of=/tmp/nbox_image.dd.
