How to check drive temperature on Linux?

Question

I have used of hdparm -n and smartctl -A but it always seem to be a "per drive" technique as a drive may answer for only one of these tools.

So, is there a standard way to get the drive temperature on Linux (HDD or SSD)? If not, what (other) tools can I use to get this information?

I like hddtemp, which provides a pretty standard way of getting the temperature for supported devices. It requires SMART support though.

Example Usage: sudo hddtemp /dev/sd[abcdefghi]

Example Response:

/dev/sda: WDC WD6401AALS-00J7B0: 31°C
/dev/sdb: WDC WD7501AALS-00J7B0: 30°C

A shorter way would be hddtemp `/dev/sd?`. – Rovanion Jun 28 '16 at 22:39

Don't forget the `type` prefix (`PATA`/`SATA`/`SCSI`) for some devices; this 8-bay [UASP](https://en.wikipedia.org/wiki/USB_Attached_SCSI) tower needs the `SATA` prefix or else I don't get any temperatures: `sudo hddtemp SATA:/dev/sd{a..h}` – genpfault May 17 '19 at 02:58
I'm getting `"drive supported, but it doesn't have a temperature sensor."` for every drive on my system, which is NOT true - the temps are reported in `smartctl`. – ghostly_s Feb 24 '22 at 15:31
And how do you hide messages that do not have a temperature or are not supported? – acgbox Jan 19 '23 at 20:19

All SMART-capable devices should respond to smartctl. And I guss that only smart-devices have a temperature reading.

All other tools will propably be more or less vendor-specific (like Dell`s omsa). IPMI might be another generic approach, but I doubt, that a temperature-reading of a storage-device is standard there.

Oh yeah, in general terms you can read the output of a thermistor using the cee language... it's like so obvious. (this answer is overly-generic) – Ярослав Рахматуллин Dec 07 '21 at 20:13

As mentioned by Rovanion, to list all drives in one go:

hddtemp /dev/sd?

Or, if you prefer a for loop:

for i in /dev/sd[a-z]; do hddtemp "$i"; done

You might want to try watch "sensors && sudo hddtemp /dev/sd?" which provides cpu and other temperature information in addition.

That's assuming lm-sensors is installed – Gordster Dec 09 '20 at 14:23

To make life easier, I have added this line to .bash_aliases:

alias hddtemp='sudo hddtemp /dev/sd*[^[:digit:]] |sort -k3rn'

Now, one gets:

$ hddtemp
    /dev/sda: Generic MassStorageClass: S.M.A.R.T. not available
    /dev/sde: WDC WD20EFRX-68EUZN0: 35°C
    /dev/sdf: WDC WD20EFRX-68EUZN0: 34°C
    /dev/sdg: WDC WD20EFRX-68EUZN0: 36°C
