{{Note|1=Arguments to {{ic|hddtemp}} are directly given in {{ic|/usr/lib/systemd/system/hddtemp.service}}. This is especially important if you have multiple disks, because in the default configuration only {{ic|/dev/sda}} is monitored. Here is how to add other drives:
* Change the {{ic|ExecStart}} line in {{ic|/usr/lib/systemd/system/hddtemp.service}} adding the drives you want to monitor, e.g.:
ExecStart=/usr/bin/hddtemp -dF /dev/sda /dev/sdb
* Reload systemd's unit files:
# systemctl --system daemon-reload
* Restart hddtemp service:
{{bc|# systemctl restart hddtemp}}

hddtemp is a small utility (daemonizable) that gives you the temperature of your hard drive by reading S.M.A.R.T. information (for drives that support this feature).


Sync and install with pacman:

# pacman -S hddtemp


Hddtemp can be invoked with the drive as the argument:

# hddtemp /dev/sd[x]

Where x is the drive.


Running the daemon gives you the possibility to access the temperature via an TCP/IP request, so you could use this in order to check the temperature from outside, or within some scripts.

Setup with systemd

Once hddtemp has been installed, standard systemctl procedures work to start the daemon:

# systemctl start hddtemp

To start it on boot, enable it:

#systemctl enable hddtemp

Setup with legacy initscripts

Start the daemon:

# rc.d start hddtemp

Add the daemon to the DAEMONS array in /etc/rc.conf to facilitate auto-start on boot:

# DAEMONS=(... hddtemp ...)


Another way to get the temperature is by connecting to the daemon which is listening on port 7634.

$ telnet localhost 7634

Or with netcat:

$ nc localhost 7634

Refer to the manpage for information like supported drives, logging, etc.

$ man hddtemp


Hddtemp can be easily integrated with system monitors like Conky, the sensors-applet for GNOME Panel or the xfce4-sensors-plugin for Xfce Panel.
