I notice that the normalised value of Western Digital's
Power_On_Hours_Count attribute appears to reflect the drive's remaining
life in months. It begins life with 100 months and then decrements this
attribute by 1 for each month of run time.
For example, one WD1600AAJS model has a POH count of 56 (= 100 - 44). The
hours count of 32377 corresponds to 44.35 months. Another drive has
recorded 33585 hours and a value of 54 (= 100 - 46). Once again the hours
count corresponds to 46.01 months.
