I think the first response from a support organization can tell you a lot about how the troubleshooting will proceed. So far Hitachi has not impressed, I received the following response to my support inquiry:
Thank you for contacting Hitachi Global Storage Technologies.
In order to better troubleshoot your issue, Please do the following;
1. Kindly check the cable or try other similar cable (Both LAN and USB).
2. Check the power adapter and power indicator.

In my original message I said that I had already verified it was not the usb or Ethernet cables that were causing the issue. I had also shows that it works with other drives.
