Just bought a new 500gb WD my book pro. Every thing (including LCD display and automatical shutdown with computer) is fine except the vibration problem. When it's just running and hasn't been accessed, there is a slight vibration; when it is accessed, there is a huge clicking sound with strong vibration; when it is under stress (busy tasks), the vibration becomes even stronger.
I haven't used a WD drive before. Is it nomal for WD drives? Thank you very much! I'm sure it doesn't happen to other brands, say Seagate and Samsung.
PS. I have run WD data lifeguard for a test: both SMART and tests are passed.
