Hi,

I'm french and will make an effort to be understandable.

I have read the Komissar's post and now I have my TS-431 fully functional.
Here the fix for this model.

My problem was on the 4th bay with the "Disk unplugged" error several times by minute.

To confirm my problem, I have powered the 4th disk with external PSU like this :
20191105_213604.jpg
20191105_213614.jpg
With this mounting, all is OK. So it's a power default like explained by Komissar.

My back plane with the MOSFET of the third and fourth bay in red circle:
20191105_224102.jpg
The MOSFET is a NTMD6P02 : https://www.onsemi.com/pub/Collateral/NTMD6P02R2-D.PDF

With a multimeter, the document above and a documentation about SATA power, my conclusion is :
- D1 S1 G1 is for the 12V
- D2 S2 G2 is for the 5v

Si, I maked short circuits between D1 and S1, S2 and S2 to inhibt the MOSFET.
Trick : there is two drain (D1 and D1) and (D2 and D2). So, you can choose any drain or overflow with tin between D1 and D1 or D2 and D2 it's not a problem.
My soldering iron is not thight so my welds are not very ** but functional :)

The backplane in place :

Thanks for the trick. My NAS was shutdown for 2 years because of this default.

I'm open to questions about this model if necessary.

Thanks !

(same post above but in French for French users those who don't speak eng/us)

Salut,

j'ai suivi le tuto de Komissar et j'ai maintenance mon TS-431 parfaitement fonctionnel.
ci-dessous le correctif pour ce modèle.

Mon probleme était sur le quatrième slot avec l'erreur "Disk unplugged" qui apparaissait sans arrêt.

Pour confirmer l'origine du problème, j'ai alimenté mon 4eme disque avec une alimentation externe, comme ceci :
20191105_213604.jpg
20191105_213614.jpg
Avec ce montage, tout est OK. Donc le problème est bien sur l'alimentation SATA comme le modele de Komissar

Mon fond de panier avec le MOSFET des 3eme et 4eme slots entourés dans un cercle rouge :
20191105_224102.jpg
Le mosfet est un NTMD6P02 : https://www.onsemi.com/pub/Collateral/NTMD6P02R2-D.PDF

Avec un multimetre, la doc du MOSFET et la documentation présentant l'alimentation d'un port SATA, nous avons :
- D1 S1 G1 pour l'alim du 12V
- D2 S2 G2 pour l'alim du 5V


J'ai donc courcuité D1 avec S1 et D2 avec S2 afin d'inhiber le fonctionnement du MOSFET.
Astuce : il y a deux drains (deux D1 et deux D2). Donc, si votre soudure bave entre les deux D1 ou les deux D2 rien de catastrophique, cela marchera quand même.
Mon fer à souder était gros donc mes soudures sont loin d'être ** mais fonctionnelles :)
20191106_211312.jpg
Le fond de panier remis en place :
20191106_211449.jpg
Merci à ce forum pour l'astuce facilement adaptable à un autre modèle. Mon NAS était au placard depuis 2 ans à cause de ce problème.
Je suis ouvert aux questions si besoin.

Merci !

My model is the TS-853A - 8 bay

I am also about to attempt this same solder joint. I have high confidence in the soldering part of it and picking the right pins.

Would it be bad to just jump all 8 mosfets on mine and have any other bays fixed then and there.
also
Will the drives still spin down if power saving is enabled if I do this fix.
----
Regardless of the questions above I decided to do all mosfets and if power saving didn't work well I would still have a server...
After my 4th rebuild I got home to find HDD 1 had been ejected. This is the first time this one has been an issue. So now 1, 3,4,5 have been issues. I will be attempting to jump the mosfets tomorrow.. Also I had completed a full SMART scan which took about the same time the entire raid rebuild took. No errors at all on any of the 5 disks plus 1 ssd.
----
Just found 6 mosfets which was confusing for an 8 bay NAS. Anyway after soldering the 6 freakishly tiny joints in various ways its back online and again doing a rebuild... 30 hours until I will know if it was successful. At the minimum the drives are online so that's a plus. I had an issue with some of the mosfets so I had to remove 2.

I have an old trusty model TS-412 that has been running for 6 or 7 years with 4x 3TB Toshiba drives. Never had an issue until I decided to replace the drives with WD Reds.

It's a long sordid tale, but suffice to say after reading through the last 20 pages or so I'm pretty convinced the changing of the drives has killed them. I'm seeing all the symptoms of a back-plane issue: the Abnormal SMART reading, the "drive unplugged" or "no disk" error... particularly when first inserting the drives and moments after the rebuild is started.

I live in a hot climate so I wonder if it's a case of dry, rigid PCB and/or combined with dry solder joins. Perhaps after years of being untouched, the brutality of swapping out the drive and applying pressure along the SATA connectors tips it over the edge!

Kudos to the people who posted their attempts at soldering their boards. Anyway I needed to register on this forum just so I could see the attached images. I wanted to collate the results for myself, so I hacked together a quick page with the posts from those helpful souls. Figured if it'll help someone else (you could make it into a PDF for yourself or whatever), I've shared the posts here: https://www.weblabsperth.com.au/qnap_nas_backplane_fix/

Well unfortunately after it finished rebuilding. I got the same error within about 4 hours of it finishing.

Just wondering, do they use the same backplanes in the 653 Pro. I haven't seen this issue at this time, but I wont be surprise if I do. Mine has been running continuously since original purchase. I have no idea when I bought it, but it was current at the time.


Incidentally, I have see the same issue on a Thecus NAS and wonder if it may be a similar problem. It was always the same drive which makes me wonder if it was one MOSFET failing. I eventually gave up on it and bout the 653 Pro which has been fantastic, but I am getting to the point that I will have to upgrade all disks as it has 6 x 4TB installed in RAID5. The next upgrade would seem to be to move to 8TB disks, but the price is a bit scary as well as the thought of doing 6 rebuilds to replace them one at a time.

Shirec, if you compare where you have soldered the wires, with https://www.weblabsperth.com.au/qnap_nas_backplane_fix/, I think you will find that you have soldered one of the wires to the wrong pins. It appears that you have soldered a gate to a drain, rather than a source to a drain. Check the photos and let us know what you find.

Thanks for the reply. I checked the posts but I confirmed that its the 4957agm. I have done d1 to s1 and d2 to s2. I metered them out and they all have a direct connection back to the bords main 5v and 12v pins from the power supply. I tried removing the mosfet entirely for hdd4 a few days ago. Last night I just had hdd1 and hdd3 both throw the error again.

Also I am not sure if its relevant to the cause. But I only identified 6 mosfets and its 8 bays. It appeared that bays 1,2,3 were run of the same mosfet. Yet just then only hard drives 1,3 failed. I am sure there is some connection here but I don't know enough about the way this runs. Hopefully someone can decode my message. :)

Very annoying considering the issue is identical to this post. I am concerned now there might be a power supply issue. I get the same kernal log error to so I checked that first.

I appreciate the help so far. I might try and remove the mosfets entirely on the rest to see what that does. Honestly at this point I am flat out of ideas.

I am probably missing something entirely. I appreciate your help.

I would also really like to know what these error codes in this log message are. This error came up within 1 hour of the rebuild finishing which took 2 days to finish.

It is exactly the reason I initially decided not to provide the fix instructions along with issue analysis. People will try to use it where it doesn't belong.

I WOULD LIKE TO EMPHASIZE, THE MOSFET FIX I PROPOSE IS FOR VERY SPECIFIC LINE OF THE QNAP DEVICES TVS-x73. IN THE ORIGINAL POST I PROVIDE INSTRUCTIONS HOW TO MAKE SURE THE SLOT POWER IS THE ISSUE. IF YOU HAVE DIFFERENT NAS AND BELIEVE IT IS MOSFET ISSUE, YOU HAVE TO FOLLOW THOSE INSTRUCTIONS FIRST AND CHECK IF IT HELPS IN YOUR CASE. GREAT EXAMPLE IS THE FIX BY MagicStuff FOR HIS TS-431.

Shirec, your issue looks different. Your backplan has different construction and I don't believe there is someone who tried to fix it before. Bottom line, at this stage you're alone to fight this battle. Good luck.

I totally understand. However at the point I am at I did not have much to loose. I will be attempting one last thing tonight and then I will have to bite the bullet on buying a new NAS. I'll be going with the extended warranty this time for sure. It has been an ordeal.

On the link with those photos I had soldered them exactly like the 4th photo. I assume the pins from the photo are 2x D1 pins and 2x D2 pins which crosses over to the gate and source pins. This afternoon I will be putting jumpers directly from the D1 and D2 pins to the power supply directly.

This is what I have done with HDD4 which is one that didn't fail this time.

I will be jumping the first 5 drives both 3v and 12v back to there original source. The only issue I see with this is that there might have been some other sort of protection before the hardrives met the power supply.

In this situation the hard drives will be directly connected to the power supply. This will be the last option that I can take as it will bypass the entire board basically.

Please someone let me know if this sounds like a horrendous idea. Cheers. I will upload a photo of my shoddy idea when i get home.

As it turns out I had ready soldered a direct line from the supply to hdd3. Now I am out of ideas.

I have exactly the same issue with my TS-453Mini. The HDD in slot 1 stopped running. I can hear that it doesn't spin up after power on. The NAS is out-of-warranty.
I contacted QNAP support, and they offered me a replacement backplane at a cost almost identical to a brand new NAS!!
They know about this design flaw, and still they refuse to give customer support. I don't mind paying, but a reasonable amount please!
I'm ready to try the soldering method now, but first I would like to verify by applying external power.
Can someone please explain in some more detail how to do that - with better pictures? Where can I buy the right cables? Links please.
