See my PM. Taking this off line...Ok rkenders, I agree with you that the components for all these rk3066 tablets are probably made elsewhere (elsewhere in Shenzen!), and Pipo, Yuanda, Cube, et al, use which ever is available and cheap. Just like Dell and HP will throw in a Maxtor or Seagate hard drive depending on which they can get cheap and works with the system specs.
So, with this example in mind, you may have received a pipo m1 with a "Seagate" hard drive and I got a "Maxtor" hard drive with mine. The fact that ALL "Seagate" and "Maxtor" drives were bad at first, and some were fixed by altering the permissions, leads me to believe there should still be a firmware fix for the other "hard drive"/ sd card chip.
Anyway, I'm willing to bet a pint on it
