The value is also sometimes larger than current. It just means that never ever before there was a value recorded that caused a decrease of the worse value. There is a FAQ on smartmontools.org about it. Then there are also temperatures where worse values are larger than current. Maybe this causes some confusion. | |

I don't understand this as "worst" is almost always "100" and another answer suggests that this is the top end of the scale for the healthiness of the metric. | |

But there are several attributes that can be fixed and they will go back to zero. All thresholds are not just warnings they show clearly that a drive has failed. Raw is the same as current. Current is interpreted by UI and raw is what the attribute really contains. Sometimes the numerical attribute values are flipped (often temperature is shown as quality or real temperature). There is no real standard what a vendor stores as raw value. | |
| Jun 9, 2020 at 11:59 | comment | added | Chameleon | No. I do not understand it. RAW value is current value because until now 8 incidents happen. Correct? Threshold value is a bound. When RAW value > Threshold value a warning arises. So, the question remains: If RAW is current value, what is current value and what is worst value? How can current value be 100 when RAW value is 8? Current and RAW are not the same? Please write more. | |

For example some vendors store temperature in Celsius and others not. They also count sectors/errors/times there and you can't really tell how bad the status is without looking at the current value. | |
