Data on hard drive?

I just purchased a WD TV LIVE HUB and it throws an error message when trying to transfer files over to the hard drive.  It is hard wired directly to a router along with the computer and keeps losing the connection but does not seem possible to me that every attempt I have made recieves the same error.  PLEASE HELP

Hi

What gives errors. What firmware are you using…etc. Just write down what you have, and what you are trying to do with a bit more detail please.

are both cables reliable too have you got an alternative patch lead?
