Cubietech is a company located in ZhuHai China, It’s a small and new company. Cubieteam is a small team, consist of several young people who are very like embeded computer technology. Cubieteam plans to develop a series of open source mimiPCs which are powerful but low costs.

If you're not going to specify a block size with dd, you can simply redirect from/to /dev/sdX:
gzip < /dev/sdX > bkp.img.gz gunzip < bkp.img.gz > /dev/sdX
you may use GPARTED to make it, but you may use other PC to help you, you can check http://gparted.sourceforge.net/ for more information. Also you can try to use the resize2fs command, e.g.
#resize2fs /dev/mmcblk0p2

Cubietruck is the second PCB model, it much different between Cubieboard&Cubieboard2. Cubietruck supports 2GB RAM, VGA jack, Wifi&BT on-board, all them need to expand the PCB size. Most important, we want it is fit a 2.5 inch HDD.
This gap was designed for HDD(Hard disk) adding

Cubietruck supports power by Li-battery even with 2.5-inch HDD or SSD. The specification of the Li-battery is almost like the one which used in most of cell phones. If you have a free cell phone battery, you can use it to power Cubietruck by soldering two wires. This Li-battery has the following key parameters: Rating voltage=3.7V, Charge voltage=4.2V, Over current>=4A. The capacity of this Li-battery is not important I think, the more the better. But crucially, you should pay lots of attention in the positive and negative pole. You will damage Cubietruck if the Li-battery electrodes are connected in wrong way. You can find out the connection electrodes on the PCB of Cubietruck. Lithium battery is a kind of dangerous goods in transportation, so you need to DIY by yourselves.

Of course yes.
