TS-251 Didnt see 2nd bay harrdisk after fan 1 was failed

[dolbyman]

you said you had issues ..fixed them via firmware downgrade

that should be adressed with qnap support then

But last night I saw I have the processor affected with this "bug" causing the NAS to fail.
And that is why I asked what should I do.
My device is working fine

Someone else with a still working NAS model affected by the hardware defect posted about this in another thread here (there are a handful of threads discussing this topic spread throughout this forum). I can't be bothered to locate the specific thread and post, sorry, but it went something like this. They contacted QNAP support and asked what they should do to prevent the premature death of their NAS. QNAP's response was essentially: you should use the NAS less and turn it off when not in use to prolong its life.

This may sound like an unacceptable answer, but there is really not much else they can do other than implementing a recall and repair/replacement program. Since the standard warranty of being free of defects is for 2 years, they are under no obligation to provide this service at no cost to the user.

The hardware failure occurs because of circuitry degradation over time inside an Intel chip (possibly the CPU itself, not sure), while powered on. The time of failure seems to vary between users, from 4 to 6 years, and it's not clear to me if CPU usage (higher or lower) is a factor, or simply powered-on time.

I'm in the same boat as you. My advice would be to have good backups at all times, and devise a plan to be prepared for the inevitable. Either go for the resistor soldering DYI solution, but that is only a temporary solution, which longevity is unknown at this point. Or budget for purchasing a new NAS (QNAP or other...). Or send the NAS back to QNAP for repair/replacement, probably at about the same cost as a new one, if not more. If you purchase a new QNAP NAS as replacement, it should be possible to just transfer the disks from the dead NAS to the new one and go on as if nothing happened, assuming they both have roughly the same firmware version. That seems to be the easiest path, but certainly not the cheapest.

Thanks so much on a detailed reply.

Please just confirm that this is covered by warranty?

My warranty is 5 years........ 2 years + 3 extended.

[Keano16]

p.s.
What is the alternative to TS-251+? I see no other alternative within 2-bay devices range.

[dolbyman]

the warranty question should be asked to qnap...not a user forum

[Keano16]

I don't agree with you. I am sure someone over here in the forums know if this is covered or not. Thank you.

actually if it works fine, my guess is the support will likely do nothing.
Within my ticket, they were pretty active, but stick to the standard issues (firmware, and revive DOM) they just gave up by offering 20% discount to buy another one (but i didn't had extra warranty).
Do not hesitate to Open a ticket and you will see.

Regarding the 100 Ohms trick, please read posts from yujungchang , he explain very well what to do. depending on the voltage between pins 1 and 8, different resitor migth be used (pull down or up).
but this is to make the device booting properly.
At some point, the CPU is degraded enough to prevent the device to boot. this trick is a workaround. but the CPU will continue to degrade. and finally will never boot up again.

In your case, as you said it is still working fine, you can continue to use your device, provided your backup plan is strong enough : continue to backup regularly as you do.

from what i could see, when finally the board couldn't boot, don't panic, the data are still on the drives. equivalent QNAP NAS could be used to recover them (migration procedure or similar), or a simple normal linux can be used to mount the array. (i used a RAID1 array, static, it was pretty straightforward to recover the data without buying another QNAP NAS)

Thank you so much

Hi, I know this is an old thread, but I think my NAS is affected by the same bug, and I'd like to know how do you found out that your processor was affected.
Where did you find information on this "bug"? I cannot find anything in the forums.

I have a QNAP TS-251+. Fan is blowing at max speed, system reported fan spinning at unearthly speed and 0°C temperature, HDD2 degradation.
I kept the system powered off for a couple days, now on bootup HDD2 led is off and I cannot reach the NAS via web nor via SSH.

Thank you in advance
Cris
