[Luki72]

And the same here with 870 EVO 50GB @ Debian testing:

After addig it to /etc/hddtemp.db like this

the result is

[Batwam]

same with the 860, it is recognised if I include the following to the db (note that the "B" in GB needs to be omitted):
"Samsung SSD 860 EVO 500G" 190 C "Samsung SSD 860 EVO 500GB"

[bortek]

Which of the fields are actually showing the right temp?

ID# ATTRIBUTE_NAME FLAGS VALUE WORST THRESH FAIL RAW_VALUE
190 Airflow_Temperature_Cel -O--CK 066 053 000 - 34

In my syslog it says

Device: /dev/sda [SAT], SMART Usage Attribute: 190 Airflow_Temperature_Cel changed from 66 to 65

which would then be the VALUE field that is a real temp and not RAW_VALUE

???

[Shanghai-Tom]

The Value field agrees with separately obtained data from smartmontools on my Samsung SSD's

However, on a my Crucial ssd its field RAW_VALUE from smartctl that matched the value from hddtemp of 40C, which given the overall temp readings of cpu, gpu, and an nvme pcie are around 60C , is the incorrect field for this disk.

ID# ATTRIBUTE_NAME FLAGS VALUE WORST THRESH FAIL RAW_VALUE
194 Temperature_Celsius -O---K 060 043 000 - 40 (Min/Max 25/57)
