How would that work when there's no means of restoring said clone onto the Chromebook after the fact? The media card reader isn't supported as a boot device due the limitations of the Chromebook BIOS. Like booting a Linux hard disk in another machine, cloning it via another computer would likely write the hardware configuration of the other computer onto the image, which of course, would not boot on the Chromebook. I hope the recovery image is stored somewhere else so all I have to do is pop hard disk in, turn it on, hit space to restore OS verification, and done!
EDIT: it does, apparently, accept the additional 2GB DDR3 RAM Memory upgrade I just placed into it though. Linux now says it has a total of 4GB over the previous 2GB
