Maximum allowed internal temperature for My Book 4TB

Model WDBFJK0040HBK-EESN

Sorry, I’ve searched all possible forums and did not find an answer on this simple question :frowning:

May someone from WD answer and/or send an URL to an official location of this information.

I need it to set an apropriate maximum temperature within Sentinel.

Hi, the operating temperature of the My Book is between 5°C to 35°C.

Dear Moderator,

I would like to pay your attention on header of my question. It is “Maximum allowed internal temperatur​e…” , rather then

" Operating temperature" (defined by WD to be 5°C to 35°C). I definitely have downloaded “Specifications for the My Book external hard drive” from your site. It was a first thing I searched on WD site, by the way. It did not help.

On the other hand, there is one more definition in this document and it is “Non-op. temperature: –20°C to 65°C”.

It is not very understandable definition, but one might consider, that in the room with 65 degrees My Book will not work.

All this is not what I asked for!

As you can know, there is some difference between external (environment) temperature and internal temperature inside a disk, as well, as another one inside an enclosure.

Software, for example, Hard Disk Sentinel, measures not a room temperature, but rather one inside a disk :wink:

A maximum value have to be set in this program, in order to send an alert, if disk go too hot.

So, one more time. What is a maximum allowed internal temperature - one, software can read from a disk controller, for My Book 4TB disk?

One of possible answers might be “It is the same, as environmental operating temperature in product specifications”, but it does not make sense. 35 degrees is too low value…

Hope to get an answer.

Valery

I’ve seen 50 C mentioned as a max temp for hard drives.

Thank you. But, to get a right answer, let me ask you a different question.

What WD disk is inside My Book Model WDBFJK0040HBK-EESN? I mean this kind of WD model number, but for a “stand-alone” internal disk, used in My Book.

Then, I believe, you or me can find an answer to my question.

I hope so, because in 2103 I have asked the same question regarding internal WD disks, I purchased and use in

my PC. This was an answer ([Deleted]., Western Digital Service and Support):

I received an answer from WD head department. It is officially confirmed that the maximum allowed internal disk temperature for our drive is the same as enviromental operating temperature in product specifications.

WD1002FAEX-00Z3A0 – 55C

Just to close a request in order someone will need a right answer from WD support department.

WD Internal hard drives maximum internal temperature is equal to the maximum environmental operating temperature. This information is only valid for WD internal storage drives, because WD External Storages have lower Environmental Operating Temperature due to the enclosure. However most WD External Storages have WD Internal Storage drives inside.

For example:

WD Caviar Green WD40EZRX

http://www.wdc.com/wdproducts/library/SpecSheet/ENG/2879-800026.pdf

Environmental Operating Temperature 0 to 60 °C Maximum internal temperature for this model equals 60 °C. This information is not open source and not specified on WD website, however I have previously already made an escalation to WD Head Department and received this confirmation.

My Book 3.0 External Desktop USB-drive WDBFJK0040HBK has WD Caviar Green drive inside, so the maximum internal temperature of internal drive in My Book is also 60 °C.

 

Crystal Disk Report can read the ident on a disk and see how warm it is along with a raft of additional information
