After having tried out Seagate Baracuda SATA series and Samsung's Spinpoint hard drives in 80GB capacities, I recently bought a WD800JD 7200RPM/8MB Buffer SATA hard drive and comparatively, its performance is tremendous. Its soundless (idle/seek both) however there is one thing I'd like to clarify. On system shutdown, there is one peculiar click/clac sound that comes once from the drive just a split second before system shut down. I asked the retailer, and he said that it was normal. So the question is, Is it really normal? Any experienced Western Digital owner?
