1 TB Drive Visible & Accessible When Hub OFF

Sunday, August 28, 2011. My WD TV Live Hub 1 TB drive is visible and accessible on my home network even when the hub is powered OFF. I have a Third-party external case with WD 2 TB drive  connected to the front USB port of the WD Hub. That drive is also visible and accessible on my home network. I was pleased to discover this feature. It’s like having two NAS devices on the network. Thanks, WD!

When “off”??

Or merely when powered down to “standby”?
