Is this a 3.5″ or 2.5″ drive ie desktop or portable? If desktop check the power supply isn’t failing and not supplying enough power. If portable try using a powered USB hub or one of those cables that have 2 USB plugs to draw twice the power.
I’ve got a couple of portable drives which click when the USB isn’t supplying enough power. Oddly if I turn one of them on it’s side it will often work.
PC World – has anyone experience with using their recovery service…?
I don’t think Gary Glitter recommends it.
