Well, I've been struggling with this same issue and i just got the system to recognize the Expander by doing something contrary to what the manual describes. I plugged it all together with the SATA cable and turned the cable box and TV on...nothing...but, then I removed the SATA cable from the Expander and the TV said something like: "hey, you removed your hard drive!" I then plugged it back in and it asked me if I wanted to format this drive. From that point it's just a matter of following the instructions and it immediately loaded up the programs. Hope this is your issue--its really a quite simple solution. Good luck.
