Hi ive purchased a new Western digital 320gb SATA hard drive for my sons pc to replace a ide 80gb hard drive. When connected and boots up the hd starts clicking and the light on pc stops flashing. In the Bios the hd is showing with no name or size. When i try and load xp from the disc it eventually starts to load then comes up with hard drive error. Can you please advise if a faulty hard drive ?
