Hello everyone!

Started my first unraid NAS and I keep running into issues. Just to give you a heads up on what I have done so far.

I bought a LSI card https://www.amazon.com/dp/B008J49G9A?ref=ppx_yo2ov_dt_b_fed_asin_title, to replace my sata expansion card that went bad and had some drives get corrupted. I have a 40mm Noctua fan attached to it. I rebuilt the array, and everything is good. I ran an extended smart test on all the drives and also did a MEM test to make sure my ram wasn't bad either. Everything came back with no errors. After doing all of that, I start my array and BOOM. The drive that I rebuilt immediately got corrupted again. Its a Iron wolf 8tb HDD as well so its built to be in a NAS and I bought it 3 months ago.

I tried going into diagnostics and searching for "error's" as a ctrl F search but didn't really get anything definitive so now I am not sure what to do.

Please help!

Do you really mean it keeps getting disabled?

Disabled and corrupted are not at all the same thing.

Syslog seems to indicate disk1 was mountable before it became disabled, so probably not corrupt. And disks 2, 3 also mountable.

SMART attributes for disk1 look OK and it passed extended self-test. Same for disks 2, 3 and parity. And new disk4.

Can you start the array in Normal (not Maintenance) mode and post new diagnostics?

It was being disabled but showing it had errors on Disk 1. Yes I was also in the process of adding another drive to my array but this popped up. I just got back and started my array again and now its not showing any errors. So I guess I am now waiting until it does it again? I am unsure if its the hardware which I don't think it is. I have replaced cables, tested drives and all the components. It has a good PSU(probably overkill).

It's not logged as a disk problem, and SMART is fine, looks more like a power/connection issue.

power/connection issue

Check connections, power and SATA, both ends, including power splitters. Make sure all cables have enough slack so they don't pull on connections. Don't bundle data (SATA) cables. Ideally no more than 4 drives per PSU cable. MOLEX-SATA splitters are better than SATA-SATA splitters.
