I have an external HDD connected to my OPi One and this are the temperatures in armbian monitor.

 

Nice! Hot stuff! Please check the output of

hddtemp /dev/sda --debug

and then adjust the template (since obviously your disk provides unusual values that need to be divided by 100). You could do that by adjusting the postprocessing rule in the used template: sprintf("%.1f", $1/100) (look at line 70 here -- if it's already 100 you need to divide by 10000 of course)

Ty for your answer !

 

root@orangepione:~# hddtemp /dev/sda --debug

================= hddtemp 0.3-beta15 ==================
Model: Seagate Expansion Desk


If one of the field value seems to match the temperature, be sure to read
the hddtemp man page before sending a report (section REPORT). Thanks.
