SATA HD doesn't work with 3TB Drives

Received my Communicator U3 SATA HDD Docking Station from Amazon today. You advertise it as compatible with +3TB HD however I just plugged in a Seagate Barracuda 3TB and my new iMac is not seeing it. 2TB WD Green drives are seen. Should I send this back on Amazon or can this issue be fixed?

Never mind, I ejected a couple times and re powered the dock and now its seeing it. Hopefully its all good now.

Hi Alex-

We’re glad to hear you were able to work this out, however please let us know if you run into the issue again or have other questions.
