Western Digital 1TB USB 3.0 - Very loosely connected?

It seems just touching it a tiny bit will cause it to lose its link to the PC, and will require to turn on and off the hard drive before it will start back up.

It works better when it is vertical than horizontal too, as in, when it becomes disconnected, making it vertical will get it to reconnect more often when you turn it on than when it is horizontal.

Are these intentional, or are they product flaws?

It could be a bad USB cable.
