Four months and you did not chase before now...?
(actually it is still less than three months, but my point is the same)
Anyway - should we assume you do not have a DMS? So the photo was not of your DMS, it came from someone else?
The real question is this... Has your Phatbox already had the hack applied? If it has not, then even with the pin-out information, you will not be able to make it work with another drive. The hack can only be applied using an original DMS.
If your Phatbox has already been hacked then it will work with a non-original DMS. Please confirm the current status of your Phatbox. I will be able to post the connection details, but it will take a little time. (not three or four months, though)
