I had the same problem and replaced the "Control Station", still same issue, but I was using the same "power adapter".....I changed out the "Power Adapter" and the control station detected the HDD.

I guess the Power Adapter was not applying the power needed to apply power to the HDD to spin in the control station. I hooked up my old Control station and sure enough the HDD was detected. I hope this helps

I bought a new hard drive now it wont detect the master hard drive or slave hard drive
