Hard drive is not working.

When you say that the hard drive works I have to ask how you know. There are not many parts in a laptop that would make a clicking noise. One of them is the hard drive. Is there any display activity at all? Lights on the unit that come on?

This means that the WD could is trying to connect to the computer but looses the connection. Try plugging the usb cord in another usb slot on your computer. Or try using another cable. Make sure the WD is not giving out any red led light on the device.

A clicking noise is a sign of hard drive failure.
If its a metal clicking noise, could be a physical damage.......hard to get data back from it.......and very very expensive.......sorry

Don't forget to rate this answer if it helps

Any hard disk that makes clicking or metallic noises is faulty, especially when POST error message no bootable devices detected.
To confirm go into the BIOS setting and see if the hard drive is detected, if it cannot detect the hard drive then it is definitely faulty.
Replace the hard drive and install Windows on the new hard drive to get the computer working again.

First thing to do is to try it on another computer to see if its not your windows playing with you.

If that doesn't work its either the USB controller inside your Hard drive box or the hard drive itself.

The only way to figure it out from there is to open the Hard drive case remove the Hard drive and either try it with another usb module that you know works or plug it right in the computer with IDE or Sata interface.

It's toast. You need a new one.

If the noise is like a repetitive ticking or clicking. Well, the sorry to say that the hard drive had crashed... which makes the noise... And sorry to tell you that you cannot do anything but to buy another...

sorry... Fixya!!!

There is a (laptop-size) hard-drive inside the case, and that hard-drive is failing. As it spins, it generates those noises, like a dying dinosaur. If it still is under warranty, exercise the warranty, and replace it. If the warranty has expired, tough luck.

The clicking noise indicates that your hard drive has failed, it won't get noticed on your computer any more.

hmm have you tried taking the bottom off and making sure nothing got hot and melted or ruined anything...???
