Is it the RAW_VALUE? The actual temperature is 37C (the raw value). The normalised value appears to be determined as follows: normalised temp = 143 - raw temp Therefore the worst case value is ... worst temp = 143 - 79 = 64C -Franc Zabkar |

In many cases a normalised value of 100 indicates perfect health for a particular attribute. In your case it appears that WD has chosen 43C as the acceptable norm, and assigned it a health score of 100. If the drive is cooler than 43C, then it is healthier (greater than 100), whereas if it is hotter than 43C, then it is less healthy (less than 100). -Franc |

Oh, and where does 143 come from?
