Find the Temperature of your Hard Drive September 18, 2005

Posted by Carthik in applications, commands, ubuntu.

So you want to know what the temparature of your hard disk drive is?

Install the package hddtemp from the Universe repository by doing a:
$sudo apt-get install hddtemp

Later, whenever you want to check the temperature of the hard drive, do a:
$sudo hddtemp /dev/hda

where /dev/hda is the hardrive designator – which you can change if neccessary.

nice one!
just curious what temp values others have. Here are mine (damn IBM Harddisk is hot)

/dev/hda: SAMSUNG SP1614N: 29°C
rwabel@RALPH:~$ sudo hddtemp /dev/hdb
/dev/hdb: IC35L120AVVA07-0: 37°C

Mine stays at around 40 on my laptop. Anything below 60 degrees centigrade should be fine – I recall reading this somewhere, but dont know exactly where.

4. kenny - September 19, 2005

both of my harddrives are running hot.
hda – 44C == 111.2F
hdb – 48C == 118.4F

5. ubuntonista - September 20, 2005

kenny, that sounds okay – not too bad actually. For my hard disk, which is a toshiba notebook drive, the range is 5deg to 55 deg celsius. Find out what the operating tempature for your hard disk is.

Here’s a little bit uf scaremongering (?) from commercial site

“According to manufactures, the normal recommended working temperature of a hard disk is 35-40°С. Once it rises by just 10°С – from 40°С to 50°С, the safety of its work becomes more than two times less!”

PS. monitoring temps for SATA drives doesn’t seem to work under Breezy because the latest version of hddtemp requires ‘SATA SCSI passthru’ (?) which only appears in the 2.6.13 stock kernel – which I don’t think they will be shipping (ie. either wait or dig out a newer kernel 😛 )

8. ubuntonista - September 22, 2005

Yes, I suspect that higher temperatures add to the reliability issues.

Too bad it won’t work for SCSI drives immediately in breezy – but as with all other kernel related issues, this too will pass 🙂

9. lennox - November 14, 2005

is there a safe way to run hddtemp without using sudo?
the temperature of my Samsung SP2014N is 26 deg Celsius, the case has a temp of 26 deg. I have a 120 mm fan sucking air into the case directly in front of the HD. According to what people told me, a hard drive cannot be cold enough, but everything below 40 degrees C is okay.
HD’s for Notebooks are designed for higher temperatures than those for Desktop PC’s, so you cannot compare these two.

10. lennox - December 8, 2005

running without sudo (but maybe not safer either):
sudo dpkg-reconfigure hddtemp

11. JimH - December 12, 2005

Just check my HD. Not so hot – 34°С.

12. Jmak - January 10, 2006

damn u guys have cool HDD’s, mines right now at 48! ive been downloading for like 20 minutes and it hasnt dropped. highest ive seen it was round 51 degrees celcius? i guess anything below 60 or even 55 is ok right?

13. me217 - January 12, 2006

on my acer aspire 3000 laptop my hdd is runin at 53c wen i was playin rise of nations but its starting to drop its down to 51c im using speedfan 4.27 which is a free program. and im runin dual monitors i dont no if that will afect it but it might. also while runin the game my cpu never changed temp just sat at 56c all the time no matter wat im doin. im guessin its a faulty reading.

14. josh - January 14, 2006

hmm. i run ubuntu, but found out my temps in windows. it is semi-offtopic, but my HDD hits 67ish when doing large backups etc. it is a fairly new, (1yr) maxtor 250GB sata drive. i was just wondering if this is actually safe.

15. bob - February 1, 2006

Ive also got a Maxtor but is a 120GB and it runs at 47ish
its only one year load but already it has alot of bad sectors.
Im running 2 8inch fans and a 12inch, motherboard running at 35ish and cpu at 35ish 3Ghz and AsusP4800E-D

16. CM - February 24, 2006

The 40Gb hitachi in my dell 8200 is running near 60, sometimes up to 62. From what I read this is too hot. However, it’s 3 years old and has no errors. The system’s fan seems to be coming on more lately even when no processor load so perhaps it’s headed for trouble.

17. joekidd - April 5, 2006

well guys, if the temp of your drive is over 50 C or in the high 40’s C, then I suggest you get a hd cooler fan that you can get for under $15. It will greatly help with your drive running at a lower temp and avoid problems in the long run. I know this because I had a 3 year old seagate drive running (5400 rpm) in an average sized desktop and died one day, most probably of over heating. I now have a 250GB maxtor sata II drive (7200 rpm) and I am using it in a small desktop pc (the one that lies flat horizontally on the desk rather than a regular desktop pc that stands vertically). This small desktop obviously has less space and is more crowded and can be dangerous in terms of hard drive overheating. I bought a hd cooling fan from tigerdirect.ca and installed it to the drive. Now, my hd temp never goes over 43C and usually runs at 39-42C, even in a small desktop. So the fan would help even more in a regular sized pc case. My drive operating temp is rated at 0-60C, so I am safe as long as I keep the drive within these temp ranges. You can use the program DTemp which not only gives you drive temp but also gives a list of features that your drive supports such as power and acoustic managment and is extremely easy to use, no installation needed.

I use Speedfan as well, it’s a great little program. My two Maxtor 300gb SATA disks run at around 45-48 degrees ambient, which I thought was quite high (hence me coming and finding this board!).

In response to what someone said about their Maxtor drive developing bad sectors quite soon, Maxtor are the shoddiest make. They’re the Packard Bell of hard disks, but they’re cheeeap. Although I don’t go for cruddy components as a rule, I figured that whatever happens I need to backup (even if I’m using some Seagate Caviars), i.e. they’re going to fail sooner or later, so I may as well spend less. They are all in a 3-yr warranty anyway, so as long as your data is backed up I dont’ see a problem.

But RE temperatures, mine are worrying me a bit, trouble is, I have fan pushing air right past them and it’s not making the blindest bit of difference. They are hot to touch, but then, think what’s going on inside!

I tried using bay coolers as well, which sit just below the disks. The annoying thing is that the fans are small = highers RPMs = more noise. This is a HTPC so needs to be quiet.

I would recommend speedfan to anyone, it’s superb for monitoring and auto-adjusting if your board has hardware health support.

19. furox - July 18, 2006

wow mines 18C ( maxtor 80gb ata )
im very suprised,
but i have got HDD coolers, on it, nice to have it at 18C though
btw nice and simple instructions thanks !

Just ran hmonitor on my server. Its running a amd athlon socket A 1ghz
and a 120gb hard drive.

Recently its gone insane, i never remember it being this hot.

Cpu is around 78 degrees. Hard drive reach 103 degrees just now. I ran into the room and switched it off as i picked up the case (which is metalish stuff) it was way too hot to touch and had to put it down immediately.

I can never remember it getting this hot b4 :S I thought the program was making a mistake but ive never found it make one b4 and as i say the case was simply burning me.

I took the side off and pointed a room fan into it, I turned it on and left it for 4 hours on full load just to test. and checked and the hd was down to about 60 degress and the cpu was at 55.

Btw the hard drive does have a dual cooling fan attachment on it cuz it was mentally hot in an old pc of mine.

21. henry - July 31, 2006

btw thats NOT fahrenheit

22. Fredric - August 1, 2006

Henry, if both HD and CPU are that hot you obviously have a high case temperature. Make sure exhaust/intake fans work properly and that the exhaust/intake vents are not blocked by dust and dirt. Might do the trick. But it’s summer hey, all temps are higher. =D

23. Eric Passmore - August 18, 2006

I was worried about my hd temp too. MAXTOR claims their drives are tested and expected to function up to 50C. I like hddtemp very easy to use, and easy to make a little rrd out of

24. CM - Perpignan - September 27, 2006

On post #16, I mentioned a 40Gb hitachi in a dell inspiron 8200 that was running near 60 degrees, but having no problems.

Well, sure enough, a few months later Windows started giving weird errors and another disk scan revealed that it was becoming corrupted. Was happy to get it replaced on warranty a few days before it expired! I highly recommend running system diagnostics (usually included on a manufacturer’s CD) a few weeks before any warranty expires.

The replacement Fujitsu 40GB drive runs at around 50 degrees in a warm room.

25. Tommie Thomas - December 7, 2006

I downloaded a free program called Dtemp and it is showing my Dell Optiplex GX620 running at 127 degrees Farenheit. My Dell has a very compact case so i am guessing that is why the temp is a little high.

how to get xserver-xfree86

27. Bruno - April 20, 2007

After running more than four hours, upgrading from ubuntu 6.10 to 7.04 from the web, the temp of the sata drive of my notebook is at 39º.
Great post and thanks for the tip.

28. IcyJ - May 15, 2007

Thanks for the simple instructions! Here are my sata HD temps for comparison:

WDC WD3200JD-60KLB0 40°C
WDC WD2500JS-60NCB1 46°C
WDC WD2500JS-60NCB1 48°C

Hi there,

Is there a way to make dual processors show in hddtemp? I’m running Feisty on an Acer TravelMate 8210, 2x 64-bit CPUs with a 120 GB HDD. Temps are:

CPU (only shows one) = 66°C
HDD = 45°C

I’ve suspected that the machine becomes too hot, especially when I work on both ubuntu and with WinXP in vmware. Could anyone please tell me what the normal range is for CPU and HDD temps?


31. ChesterDKat - September 15, 2008

I’ve added hard drive cooling fans to hard drives in my ubuntu 8.04 file server. It’s a PIII with a few Seagate 500GB IDE drives. The fans lowered average temps from 45C to 32C! Pretty impressive. The fans that I’ve used are Vantec’s HDC-701A’s for what it’s worth but I bet most fans deliver about the same level of protection.

Can I just say what a relief to uncover a person that genuinely understands what they’re discussing online.
You definitely know howw to bring an issue too light and
make it important. More and more people should look at this and understand this side of the story.
I can’t believe youu are not mre popular since you surely possess the gift.

37. Memoria 2GB DDR 400 - May 30, 2014

Definitely believe that which you stated. Your fazvorite justification seemed to be on the web
the simplest thing to bee aware of. I say to you,
I definitely gett annoyed while people conzider worries
that they just do not know about. You managed to hhit the nail upon the top and
defined out the whole thing without having side effect , people could take
a signal. Will likely bee back tto get more. Thanks
