You can see the block /dev/block/system mount on /system,

then you connect SATA with Cubietruck,and see what block is the SATA:

  $ls /sys/devices/platform/sw_ahci.0/ata1/host0/target0:0:0/0:0:0:0/block

You will see the SATA block(maybe it’s sdb, sdc or sdd,but it’s no problem):

Modify the SDK

After you copy the system file to SATA,you should modify SDK:

  $cd /ct-droid1/android42/devices/softwinner/sugar-cubietruck/  ls
  $vim init.sun7i.rc

And “mount ext4 /dev/block/system” changes to “mount ext4 /dev/block/sda”,like that:
