When I run sudo hddtemp /dev/sda I get the following result:
/dev/sda: KINGSTON SA400S37480G: 36°C
However, at the disks GUI I get a different reading (99°C):
Why is there a difference? which one is correct? can I get a third reading somehow?
To make things a bit stranger, I have a second ssd. It shows as 36°C on disks and 34°C on hddtemp
Ubuntu 20.04 LTS
edit: digging into the smart self test variables I found this:
I seems there are two temperature readings there, one is 36 like hddtemp and the other is higher
PS: I tried running the self test but it shows an error message: sk_disk_smart_self_test: Operation not supported (udisks-error-quark, 0)
