I got a hard drive delivered today and it seems to work but it has a tinkle when shaken - Like there is a tiny little loose screw inside the casing. I know nothing of such little black boxes and this maybe normal, which I doubt. Before I go marching into PC World with receipt in hand I thought I'd just ask on here to make sure that it isn't meant to make this noise.

It's Saturday tomorrow and a simple trip to PC World will turn into a two hour food shopping experience so I don't want to go unless it is knackered!
