First off, this is not a new install. It's been working without any changes for 2-3 years now. So, that makes me believe that it might be hardware failure. But, I checked the GUI today and saw that two of my disks had a little red 'x' where there is normally a green dot. I see 66 errors under both drives.

 

Following error under the logs of Disk 5 "ata11.00: exception Emask 0x0 SAct 0x10 SErr 0x0 action 0x6 frozen" here is the full log.

Disk 6 had no such errors but still didn't show up in this at all.

I found this topic on it:

 

But I believe it might be different. Their error seems to be for a bad parity check and mine isn't even able to do a parity check. From my understanding.

 

I also found this one:

But, I'm not sure what to take from it..

I have attached the diagnostics report. I am not sure where to go from here.

Marvell controllers are NOT recommended but might work if you disable VT-d

 

Disks 5 and 6 are not seen so they must have disconnected, but emulated disks 5 and 6 are mounted so you should be able to rebuild them since you have dual parity. If you can get them to show up.

Do they just go bad more often? Or is there a problem with their drivers? I just wonder because I've been using it for a while with no problems.

 

I found this guide:

 I googled: Asmedia ASM1064 and found https://www.amazon.com/FebSmart-Expansion-System-ASMedia-Controller-FS-S4-Pro/dp/B097R6MQBT Would you suggest this?

 

Thanks for your time! I will try new SATA cables, hopefully tomorrow. But, if that controller seams to be causing the problem, I'll order a new one tonight.
