Can't See Seagate USB HD attached to WDLive TV on network

Just bought livewire to connect my WD LIve TV and the Seagate USB HD attached to it to my home network.  I can see the WD Live TV on the network but not the Seagate.  Any ideas?  I take it I should be able to see it and copy files to it.

It’s late at night and I think what solved it was correctly setting the correct workgroup name in the WD Live TV (someone had give it to me).  Then I was able to see the IP in Cisco Network Magic Trial.  After that it was a simple matter of typing \ip address in browser and them mapping as network drive.
