Broken Western Digital Elements 320gb external hard drive

Hello,
I accidentally dropped my external hard drive from a low table. It was connected to my laptop and I was using it at the time. It landed upside-down on a soft surface (my bed) and proceeded to start making an unfamiliar noise. The computer refused to recognise it and it now seems to be totally useless. It still powers up (the blue light comes on when it is connected to mains electricity) but it makes the nasty noise for a while then powers down. My warranty has run out so I can't send it back to Western Digital. Please help me!
