My Book 2TB Is freezing my laptop and does not work? (Only had it 1 week!)

I am using Vista,  if i go to disk management when it is connected nothing loads up at all not even drive C and D and my laptop freezes. Then as soon as I unconnect the drive the C and D drives appear in disk management and the laptop works perfect.

It seems I am going to lose all files on the drive as it is not possible to plug it in to any computer as I have tried it in two others and had exactly the same results.
