Strange noise coming from 10TB drives (WD100EFAX)


I am no hardware expert but maybe you or somebody else here:

is there no possibility that something tells the HDDs to do something? A defective controller?
A BIOS? You wrote, our modern NAS are computers, I agree…don´t they have some kind of BIOS?
A defective Software Raid that continues to malfunction when the drive is virtually removed from the NAS?

But again, if this for example is a defective software raid or a software raid incompatible to the HDD-firmware, why do the beeping sounds start in my case after 1-1,5 days and not immediately after starting the NAS?


My last 2 hypotheses for this evening:

  1. it is very unlikely that we all here have bought several same drives with exactly the same error, so I think the hardware of the drives is ok.

  2. If there is a HDD FW issue, then the 10 TB Red Nas drives are in the market for 1,5 years now, am I right? Enough time for WD to present a FW update, or if we can´t update to a new FW, WD had enough time to ship the latest drives like mine (bought one month ago) with a correct FW !!!


Ok so I bought my disks more or less in two batches:

  • first batch about 8 months ago (June 2018)
  • second batch a month ago (Feb 2019).
    All 9 drives show the same make (68LHNPN0), and the same FW (83.H0A83).
    First batch was bought from a local dealer in France, while the second batch was bought directly from the WD online store.

I remember having noticed this sound since July 2018, so I guess it must have started right away when I set the disks in my NAS.
I contact WD support back in October about this noise, and had passed 3 drives through DLG, with a “pass” result.
I’ve passed all my disks through the Extended SMART test on the NAS directly, and they all pass.
I do this regularly (I used to run it monthly, now I set it to once per quarter). The test takes ages though (36-48h on the 10TB, used to be around 18h for the 4TB so it looks consistent to me).
I’ve checked the various SMART counters individually, and didn’t notice any suspicious value.
I didn’t notice any performance drop either, nor heating, etc…

And so far, it seems to me only the disks from the first volume make this weird noise.

The first volume is my “main” volume, and all packages are installed on it. I should also add Docker and VMM in the list BTW.
The second volume is only used for storage : backups, long term archives, etc.

I’ve also noticed the noise isn’t produced on a regular basis : I can hear it one day early in the morning, the day after in the middle of the afternoon, etc… as if it was produced every 18 to 36 hours, randomly.
I didn’t manage to narrow it down to a particular activity.

I also noticed that the noise usually appears when disks are not used to write/read anything. Then, if I initiate some activity on the NAS (writing large file for instance), noise vanishes, until the write is finished.
As if something was waiting for low I/O on disks to run, which would trigger the noise.


this sounds as if it could be the already discussed media scan,


That’s exactly my experience as well.
It might be related to PMR technology, like I mentioned earlier in this thread. It has to do with the drive writing/moving bits into the deeper parts of the platter.
If that process is the source of the sound, it could explain the noise disappearing when stressing the drives by writing/reading data, therefore interrupting the process.


…and once anything written into deeper parts, the beeping finishes? So once I copy my data onto the HDD and the PMR technology takes several hours, and I don´t copy a lot of stuff onto the HDD anymore, the beepig is away forever???

I have never had this noise on any HDD I ever had, why has only this HDD the PMR technology then???


Probably not, I’ve had this problem since I bought the drives, 27 weeks ago.

PMR has been used by WD since 2006, but maybe this sound issue only have become a problem now that the platters used in the drives have much bigger capacity?


I am still confused…but I come more and more to the conclusion that the drives are ok.

There may be a BIOS or LINUX error or incompatibility…

But if not, if anything is alright…



I have re-started my NAS Friday, 8th. So far, the beeping noise hasn´t come again. It is by far the longest time without the beeping noise. I have not done anything else than before. I have only installed and run QSync app so far.


the beeping has come back after 3 days being quiet. It came back for no obvious reason and it went away after a few Hours.

Today, I got News from QNAP: they could not find anything strange or a failure in the log files of my NAS…

they told me to Keep watching when the beeping occurs…….as you can read above, it occurs for no obvious reason, so I am not knowing more than before……


Can confirm that I still hear this sound as well. QNAP NAS, QTS, not able to see/hear/smell anything systematic related to the sound, which seems to appear at random more or less. I have in some ways given up, and I have the NAS in a separated room. Will, however, look into this thread at a regular basis to see if a solution unfolds and please let me know if I can provide any information that would help solve the problem. Thanks for your efforts guys.


the same as me, the same will I do


I had two 12TB Seagate Exos enterprise drives and they were making basically the same noise as these 12TB WD Gold drives are so I believe it must be with these multi platter high capacity drives or something for sure causing this. It is really irritating and driving me mad I am sending drives back and forth for the same noise.
