Listmates,
How accurate are the SMART Attribute 194 Temperatures? I ask because I have 2 drives that are reporting at, or over, 160 C (161 C = 321.8 F). However, the drives are just warm to the touch, not Hot at all. If the drives were really hot enough to cook a roast, I would expect the outside of the drive to be at least "hot to the touch". With the case open, I can rest my hands on the driver without any discomfort, all the while, smart is reporting:
Apr 24 07:47:17 trinity smartd[3627]: Device: /dev/sda, SMART Usage Attribute: 194 Temperature_Celsius changed from 161 to 166 Apr 24 07:47:17 trinity smartd[3627]: Device: /dev/sdb, SMART Usage Attribute: 194 Temperature_Celsius changed from 166 to 161
Anybody looked into this issue, or is SMART just OUT SMARTING itself?
These are 'normalized' values, within the range of 0-255. If you want more useful information, you need to look at smartctl -a /dev/sda and look for the RAW column.
