You're welcome. By the way, the Sandisk Connect Wifi Stick is only 200GB, not 250, but it is also so voluminous and very handy. Should be available for Christmas... whether at Digitec, I don't know.
You can't connect a HD but you can connect USB memory sticks. Another solution is a Wifi Seagate HD (1 or 2 TB) and connect it via Wifi and watch videos and films (or SanDisk 250GB memory stick with WiFi).
