guzu / hddtemp Goto Github PK

Running default, I can only see my SATA SSDs:

$ sudo hddtemp
/dev/sda: Samsung SSD 870 EVO 2TB: 31°C
/dev/sdb: Samsung SSD 870 EVO 2TB: 30°C

I am able to get hddtemp to display the NVME drive and temp properly if I specify the drive:

$ sudo hddtemp /dev/nvme0n1
/dev/nvme0n1: WD_BLACK SN850X 4000GB: 39°C
$ sudo hddtemp /dev/nvme1n1
/dev/nvme1n1: WD_BLACK SN850X 4000GB: 42°C

However when I try set this up as a daemon and poll for the temperature it doesn't report properly:

$ netcat localhost 7634
|/dev/sda|Samsung SSD 870 EVO 2TB|31|C||/dev/sdb|Samsung SSD 870 EVO 2TB|30|C||/dev/nvme0n1|WD_BLACK SN850X 4000GB|UNK|*||/dev/nvme1n1|WD_BLACK SN850X 4000GB|UNK|*|

Running hddtemp --debug, I don't see temperature data:

$ hddtemp --debug /dev/nvme0n1

================= hddtemp 0.3-beta15 ==================
Model: WD_BLACK SN850X 4000GB


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.

$ hddtemp --debug /dev/nvme1n1

I'm not sure how to get the SMART attribute number for temperature, but it is present:

Please advise if there's something else I should try.

Hi, Emmanuel!
I would like to maintain the project upstream if you have no free time for it. Will you allow me?
I have committed all patches from Debian, Fedora, and ALT Linux, fix some bugs and made the new release:
https://github.com/vitlav/hddtemp

# smartctl /dev/disk/by-id/usb-TrekStor_DS_maxi_m.u_00E913cb-0:0 -a -d usbsunplus |grep Temp
190 Airflow_Temperature_Cel 0x0022   071   043   045    Old_age   Always   In_the_past 29 (Min/Max 29/50 #5)

However there is another issue as hddtemp can't read the file path at all:

# ls -al /dev/disk/by-id/usb-TrekStor_DS_maxi_m.u_00E913cb-0:0 
lrwxrwxrwx 1 root root 9 Aug 17 08:38 /dev/disk/by-id/usb-TrekStor_DS_maxi_m.u_00E913cb-0:0 -> ../../sdc

as stated the original site is down and information that was moved to savannah is hard to find now hence getting the latest version of hddtemp.db is a bit of a pain.
I would suggest to update the README file and maybe add the hddtemp.db to the repository or create a new repo containing this database.
thanks for this nice utility

The openSUSE package includes an additional patch https://build.opensuse.org/package/view_file/utilities/hddtemp/hddtemp-0.3-beta15-sata-sense.patch?expand=1 (https://lkml.org/lkml/2006/12/19/131).
The patch removes a SATA check.

hddtemp doesn't show the temperature for the Sabrent EC-SNVE USB-C to NVMe/SATA enclosure but smartctl can see it:

# hddtemp /dev/sdb
/dev/sdb: Sabrent:  drive supported, but it doesn't have a temperature sensor.

# hddtemp -D /dev/sdb

You can tell me which commands i should use for extract all technical information can be usefull for devs of hddtemp.

One of my drives takes a long time to response and hddtemp sometimes returns "Success" instead of the actual value.

hddtemp -D /dev/sde

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

/dev/sde: Success

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.

Sometimes it returns correct output:

Debian seems to ship a newer patchset, revision 52, since a while: https://packages.debian.org/source/wheezy/hddtemp

It would be nice if you could import that into the official source-code.

openSUSE Tumbleweed

Since 2022-08-13 something removes hddtemp package.

I reinstall hddtemp then next day I check that hddtemp is removed.

It seems that updating the OS removes hddtemp. The OS is updated each day.

Add support for enclosure bypass to drive SMART attributes?

Maybe have hddtemp call smartctl from SmartMonTools, to achieve this? In my case, the enclosure does not support SMART, but the drives installed do:

# smartctl -d sat -a /dev/sdi | grep 194
194 Temperature_Celsius 0x0022 100 100 000 Old_age Always - 31 (Min/Max 16/55)

So if hddtemp could use SmartMonTool smartctl, that would be wonderful for my use case. And, if you added this feature, hddtemp could update its own db file over time!

Please add the following drive to hddtemp.db:

"WDC WD30EZRZ-00Z5HB0" 194 C "Western Digital Blue 3TB SATA3 5400RPM 64MB"
