It’s not. Please read the end of the smartd man page (NOTES). For example, in the message: ‘Device: /dev/hda, SMART Attribute: 194 Temperature_Celsius changed from 94 to 93’ the value given is the Normalized not the Raw Attribute value (the disk temperature in this case is about 22 Celsius). The -R and -r Directives modify this behavior, so that the information is printed with the Raw values as well, for example: ‘Device: /dev/hda, SMART Attribute: 194 Temperature_Celsius changed from 94 [Raw 22] to 93 [Raw 23]’ Here the Raw values are the actual disk temperatures in Celsius. The way in which the Raw values are printed, and the names under which the Attributes are reported, is governed by the various ‘-v Num,Description’ Directives described in the smartd man page. Please see the smartctl manual page for further explanation of the differences between Normalized and Raw Attribute values.
