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...
