It's a single 8GB.
I've only tried MP3 Player Utilities v1 and 3, as I've only been working with the tools from the disc, up until now.
The device has never worked properly, from what I can tell. I formatted it before I ever got a chance to test it, but I doubt this would've caused a problem.
As far as the firmware is concerned, it's version 9, making it impossible to extract with most of the s1 tools. S1Clone and S1Res both say "Semaphore timed out" when I try. If I were able to do it, I would've already submitted them to the Downloads, as they seem to be non-existent right now.
EDIT: If it helps any, this is what mydigit.cn has on it:
