OK, downloaded WD SmartWare software and this can see my drives and has indexed them, although not sure where or how, given I cannot discover the mybook hard drive!
There are five tabs at the top of the tool: Home; Backup, Retrieve; Settings; Help, but Backup and Retrieve are not active.
What OS and security software are you using? I just had trouble with networking on my VMware virtual machines. It turned out to be a setting in Comodo firewall on the host. They had been working probably some update caused a change.
