Well the answer was probably just from a first level support person so nothing one should get excited about. Anyway to the high Load_Cycle_Count; if I understood the technology correctly the WD GreenPower drives are exactly "Green" because they unload the heads on a plastic ramp (no landing zone!) quite often during longer idle periods. Thus they can power off the positioning logic and actuator of the heads. -> safe Power This also explains why the power usage under seek is comparable with other "non-green" drives...
<snipped a lot of stuff> > 193 Load_Cycle_Count 0x0032 197 197 000 Old_age Always - 10233 my 1 TB drive has also a relative high value:
193 Load_Cycle_Count 0x0032 200 200 000 Old_age Always - 2786
