 Re: [smartmontools-support] How do I have to interpret these numbers? From: Bruce Allen - 2008-08-25 06:09:12 ```I have something to add to this discussion. The worst value of Attribute 190 shows 44, meaning a maximum drive temperature of 56 Celsius. Just for fun, you can can probably also decode the raw value 638976037. This is (hexidecimal) 0x26160025, and *might* mean (all guesses!!): 0x26 = decimal 38 (average temperature?) 0x16 = decimal 22 (lowest temperature?) 0x00 = decimal 0 0x25 = decimal 37 (actual temperature?) I suggest that you watch this for a while and see if you an figure out what it means. Then write to this mailing list with the information.

 [smartmontools-support] How do I have to interpret these numbers? From: Alexander Puchmayr - 2008-08-24 08:08:37 ```Hi there! I really get strange temperatures when I run smartctl on one of my two maxtor-SATA-Drives; There seem to be two temperature attributes, Attribute 190 and 194. While 194 is showing 37°C, which seems to be reasonable, attribute 190 shows really unbelievable values: Value=63 raw=638976037. As I'm pretty shure that the drive is not operated by a nuclear fusion reactor, the value of 63 billion degrees is not a temperature in °C. Also the value 63 seems to be rather high, because I can touch the drive with my bare fingers and it feels just hand-worm. So what is this attribute showing?

In your case, it seems to have a value of 100C - your_temp, so 100 - 37 = 63. Usually this is done to make it consistent with other attributes - the lower the attribute value, the worse it is. The raw value may have an additional information (e.g. lifetime min/max) encoded in it, so just ignore it. So, there's nothing wrong with your drive. Just monitor Attribute 194, 37C is quite allright. Thanks, Alexander ```

Do you happen to know how many logs the sct temp history can report, is this drive specific or specified by the ATA-7/ATA-8 spec? Justin. ```

With the default interval of 1min, at least the last ~2 hours are logged (persistent!). If the drive supports "SCT Feature Control" ('smartctl -c ...'), then the logging interval can be changed by 'smartctl -t scttempint,N[,p] ...'. Cheers, Christian ```
