That's fine.

Does any of the above sound suspicious that could lead to this? To eliminate the kingwin enclosure as the source of the problem, I connected the drives directly to the JMB card and then powered the drives using my sata power splitter directly. I still got the same issue, hence I ruled out the external enclosure to be the source of the problem. However, power is something I haven't switched. I did use the same way to power another 3.5inch disk and connect to my computer via USB (to copy some data - I have a sata to USB cable), and it worked fine. So I didn't think the power supply can be a problem. However, I didn't power 2 drives together. 

No abnormal observe for the power issue.

The logs are after I started the Array Building operation and parity was being computed. I still see the progress in the unraid UI, but see these errors in the logs/dmesg.

I miss that, WD were in production not disable and never throwing error, so problem may happen on specific disk/model only.

Do you have a 3rd disk ( best not Segate Ironwolf ) verify this ? So we may narrow down the problem a bit.

Is this error something I can ignore if the read/write goes through? I'm a little confused. 

I don't agree ignore those error, but sometimes ......

 

 

 

Some issue about specific Ironwolf disk with LSI controller ( but not likely your case, so take as ref. )

I don't have a new disk yet (i already ordered one - should arrive in a few days), I am getting another WD 8TB to add as a data drive. I have a feeling, its not related to the drives itself. I have tried 3 drives till now, in different ports and different configuration. But I keep getting these ATA errors. They dont always happen in the same port. Initially i had 2 WD drives (8TB) but I got similar errors. I am waiting to get the new drive and test again with the 8TB (parity + data). 

Today I also tried installing the original iocrest board onto another NUC7i3 I have lying around, with the same errors. So I dont think its a bad motherboard as well.

As an update, I am still waiting for a new disk to test. However, meanwhile i replaced my power supply to the HDDs. I was using an AC -> molex as I described previously. I swapped it with a SFX psu instead. I read a few more spec sheets and error codes, and I suspect its due to insufficient power to the hard disks. I have cautiously optimistic to report that I haven't seen any "link down" errors since I swapped it out. However, I want to test this out once I have the new disk with me. Will report back with results.

Overlook and misunderstand you have try different power source, now I agree it is power problem. What is 5v and 12v individual ampere (A) rating of that power adapter ? Does less than 5v (2A) and 12v (4A).

It said 12v/5v 2A. I dont think i saw 4A anywhere.

That rating really can power up 1 disk, no more.

I got the new disk. I can confirm it was the power issue only and not the card. Thanks everyone for patiently helping me in this process. Really appreciate all the constructive direction I got while debugging this. Cheers!
