This thread got me interested.

I have 3 WD 2TB green drive in a 6 disks RAID5 array.

2 are WDC WD20EARS-60MVWB0
1 is WDC WD20EARS-00MVWB0

however, the 00MVWB0:
  9 Power_On_Hours          0x0032   093   093   000    Old_age
Always       -       5435

 11 Calibration_Retry_Count 0x0032   100   253   000    Old_age
Always       -       0
 12 Power_Cycle_Count       0x0032   100   100   000    Old_age
Always       -       15
192 Power-Off_Retract_Count 0x0032   200   200   000    Old_age
Always       -       11
193 Load_Cycle_Count        0x0032   148   148   000    Old_age
Always       -       157853
194 Temperature_Celsius     0x0022   116   109   000    Old_age
Always       -       34

I find it weird that load_cycle_count is so different between the two
models. They are only about a month apart..
