I do not recommend hddtemp. My application fails because of it.
I run it about 30 times and in the middle, it fails. It causes an error on the bus. I’m looking for something better.

You can put a small fan in front of the drives ( in the front of your comp-case ). this well draw fresh (cool) air in and blow it over the Harddisk and cooling it. Also, place your computer on the floor ( the air is cooler on the floor )

I am having this problem : I use hddtemp (daemon) in combination with conky. My 4 internal drives report just fine, but my 2 external sata-drives connected with usb don’t report the temperature ( -> N/A in conky ). The internal and external drives are all Samsung model 103SJ / SI or UJ. ( i tried putting sata: in front of the device name in the conky config file. When i try hddtemp in terminal ‘hddtemp /dev/sbb’ i get ‘/dev/sdb: SAMSUNG HD103SI: S.M.A.R.T. not available’, when i try ‘hddtemp sata:/dev/sdb’ i get a several lines of weird characters and the correct temperature behind them)
Any suggestions how to fix this ?

Hi,
Mine is 59C! It’s too hot. You said cooling options, please someone tell me how can I cool down my hard drive?
Laptop: Acer Aspire 5536
Linux: Ubuntu 10.04
Here’s the output of hddtemp command:
sudo hddtemp /dev/sda
/dev/sda: WDC WD3200BEVT-22ZCT0: 59°C
Thanks in advance.

Most modern RAID controller expose themself to you via different device name under Linux. See this FAQ. Also cli tools provided by RAID controller can be used to obtain the same info. It all depends upon your RAID card. However, hddtemp may not work for RAID based hard disk, use smartctl command:

smartctl -d scsi --all /dev/sg1  | grep -i temp
Temperature Warning Disabled or Not Supported
Current Drive Temperature:     23 C
Drive Trip Temperature:        65 C

This is from Adaptec 5405 SAS running FUJITSU hard disks.

Hi,

First off, thanks for the great tutorial and information.

I have a question. How does this work with RAID drives, or can it? For example, all of my servers are running either RAID-0,2,6, etc and usually all the drives show up as one in linux (ex: /dev/sda).

I have not tried this method yet, but I’m wondering if and how this would work with RAID (where a raid controller connects the drives to the system).

Thanks,
Luc

Philippe,

I’ve updated the post. And yes, it works with hdd info using a USB drive directly connected to system or via docking station.

Yes, it works with laptop docking station connected via USB.

Hi Vivek,

SteveH is right there is a typo (should be the same device ! sda )

And Andrey ask a useful question: Is it possible to get any SMART HDD info using a HDD-USB drive ?

TIA!

Hi!
Thanks for your blog!
Tell me please, will it work for me if I use the SATA Docking Station, so the hard drive is connected to my computer via usb?
What am I supposed to do?

To see temperature for /dev/sda, enter the following command:
# hddtemp /dev/sda
Output:

/dev/sdb: WDC WD2500YS-01SHB1: 25°C

The output should also be /dev/sda not sdb.

Thank you, just what i need fore my server in my closet :)

But i think i will make it beep fist and if the temperature raises further then shutdown.

This is my cron script using the –numeric arg:
#!/bin/bash HDDS="/dev/hdc" HDT=/usr/sbin/hddtemp LOG=/usr/bin/logger DOWN=/sbin/shutdown ALERT_LEVEL=55 args="--numeric" for disk in $HDDS do if [ -b $disk ]; then HDTEMP=$($HDT $disk $args) $LOG "HDTEMP for $disk is $HDTEMP" if [ $HDTEMP -ge $ALERT_LEVEL ]; then $LOG "System going down as hard disk : $disk temperature $HDTEMP exceeded its limit" sync;sync $DOWN -h 0 fi fi done

Check hddtemp-0.3-beta15/src/hddtemp.c
on line 227, the hddtemp tool can also print out just the temperature value. No need to parse the output and fetch the value from a formatted string.
Just issue this command:
/usr/local/sbin/hddtemp /dev/hdc --numeric

pete — Wed, 09 Jan 2008 09:30:30 +0000

this program has an error with my version of hddtemp.
$4 should read $3
‘ should read ‘
so the line should be:
HDTEMP=$($HDT $disk | awk ‘{ print $3}’ | awk -F ‘°’ ‘{ print $1}’)

additionally, if a shutdown is to occur, and there is more than one hard drive, the shutdown command will be executed for the number of hard drives that exceed the temperature. i am a linux newbie and don’t know if this is relevant.
