hddtemp with an old database

[Sergio Benjamim]

It seems that hddtemp has an old database.

I tried to get temperature of a Samsung SSD 840 PRO, and got an error:

sudo hddtemp /dev/sdb
WARNING: Drive /dev/sdb doesn't seem to have a temperature sensor.
WARNING: This doesn't mean it hasn't got one.
WARNING: If you are sure it has one, please contact me (<email address hidden>).
WARNING: See --help, --debug and --drivebase options.
/dev/sdb: Samsung SSD 840 PRO Serise �: no sensor

But, with sudo hddtemp --debug /dev/sdb

================= hddtemp 0.3-beta15 ==================
Model: Samsung SSD 840 PRO Serise �

field(5) = 0
field(9) = 16
field(12) = 11
field(177) = 0
field(179) = 0
field(181) = 0
field(182) = 0
field(183) = 0
field(187) = 0
field(190) = 35
field(195) = 0
field(199) = 0
field(235) = 1
field(241) = 140

The temperature of this SSD is the field 190, in Celsius, I saw it in SMART Data & Self-Tests of Disks app.

Status changed to 'Confirmed' because the bug affects multiple users.

Same Problem here.
field(190) is a possible candidate for temperature in °C!

# hddtemp --debug /dev/sda

================= hddtemp 0.3-beta15 ==================

To fix:

echo '"Samsung SSD 840 Series" 190 C "Samsung SSD 840 Series"' >> /etc/hddtemp.db

I already informed the author. (maybe not the first, hopefully the last)

[Clemens Kirchgatterer (clemens-8)]

for the PRO series the line in /etc/hddtemp.db has to look like this:

"Samsung SSD 840 PRO Serise" 190 C "Samsung SSD 840 PRO Series"

mind the typo in the first string "Serise" it really is like that!

FWIW, this whitepaper from Samsung confirms that 190 is the temperature:

[Jack (jwright-bigpond)]

For the 840 EVO 120GB this line worked in /etc/hddtemp.db

"Samsung SSD 840 EVO 120G B" 190 C "Samsung SSD 840 Series"

Note the space between G and B.

And for my 250GB evo --> echo '"Samsung SSD 840 EVO 250G B" 190 C "Samsung SSD 840 EVO 250G B"' >> /etc/hddtemp.db
