• Hddetemp vs hddtemp

    Hi everyone,

    maybe this info is helpful for someone:

    With "hddtemp" there's a tool out, capable of monitoring harddisks' temperature. This may help to prevent them from heat death.

    Unfortunately, hddtemp (every version I know of) can only access internal drives. External ones can not be read. Don't know why.

    So, I developed a little workaround and called it hddetemp (e for
    external, also). It is now also tested under Raspbian OS.

    Here you see the difference:

    [542 root@rpi-inst /]# hddtemp /dev/sda
    /dev/sda: Generic External: S.M.A.R.T. not available

    [543 root@rpi-inst /]# hddetemp /dev/sda
    /dev/sda: Hitachi HTS545016B9A300: 25 (Min/Max 16/43)°C

    There is the main HD info program
    hdparm
    man hdparm

    # hdparm -H /dev/sdb
    /dev/sdb:
    drive temperature (celsius) is: under -20
    drive temperature in range: yes

    That is with my external 3 TB Toshiba drive
    Not sure 'under -20' makes any sense.

    I tried your code, installed 'smartctl':

    # hddetemp /dev/sdb
    /dev/sdb: TOSHIBA MQ04UBB400: °C

    So.. may work for some drives.....

    smartctl of smartmontools, knows the temperature.
    It looks at location 190 and 194, depending on drive type.
    Some devices will require smart passthru, to gain access.

    suso smartctl --all /dev/sda | grep -i temperature # basic idea, remove the grep and review by hand

    And gnome-disks seems to as well, got both drives (local sata, USB SSD),
    It would be interesting to see what cluster of utilities gnome-disks uses.
    This is my go-to tool for daily usage.

    inxi -F seems a bit lame in the temperature department, getting one of two drives.

    The hardware has all sorts of quirks, so this is a topic
    for individuals with the time to spend on it.

    UPDATED WHEN_FAILED RAW_VALUE
    [...]

    Hi Marco,

    implementing this code into hddtemp source would be nice, but looking at

    http://download.savannah.nongnu.org/releases/hddtemp/

    (official homepage) it seems that hddtemp is no longer maintained.
    Updating the drives database is not enough to get ahead here.

    Thanks, best regards,

    Is Hddtemp just a spinning drive-type tool or is it applicable for Solid
    State Drives as well??

    Why should that matter?
    There is a temperature sensor that need to be read out, regardless of
    the technology the disk uses.
    But according to the other post hddtemp is very old, so it is from a
    time where SSD weren't common.

    What works for me (on SSD):

    nvme smart-log /dev/nvme0 | grep temperature

    from "man nvme" ;

    <quote>
    NVME(1) NVMe Manual NVME(1)

    For reasons that escape pretty well everyone, the SMART table on
    legacy HDD and on the new SSD, don't match. You would think there
    would be value, having entries with the same name, at their
    traditional address. I would guess that is too easy.

    Some environment information is pinned out in ACPI tables, such as
    CoreTemp from your CPU. One of the improvements in reading the
    hardware monitor interface on the SuperIO, was for the BIOS to
    wrap some of the information, making it easier for userland applications
    to "consume" the information. For example, the scaling resistors on
    the voltage measurement section, if you use the ACPI table, the
    voltages are already scaled for you. And that saves an unbelievable
    amount of labor. In the past, humans used to submit empirically
    derived scale resistor info, to the maintainer of MBM5, per motherboard
    design. And that sucked as a method. Having the correct values
    computed by the BIOS designer, and passed via ACPI table, made
    so much more sense.

    But not everything in life is that easy. Thus, we're still fiddling
    with SMART tables in the year 2022.

    I assume NVMe temperature is the same as SATA SSD, but that would
    be a rash assumption unless verified. Even an eMMC chip, could have
    its temperature information, delivered in some other way. And USB
    flash sticks, I've never seen a measured value printed on a screen,
    for those.
