Matthew, I am still confused. If the wear leveling count counts back from 100, one drive has a raw value of 3 and the other one has a raw value of 22. ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 177 Wear_Leveling_Count 0x0013 098 098 000 Pre-fail Always - 22 177 Wear_Leveling_Count 0x0013 098 098 000 Pre-fail Always - 22 However, the VALUE column has a value of 98. Not sure of the units for either column...
