I have seen this before in 6TB drives a bad disk can make another increment. Just got done putting 4- Ironwolf Pros 12TB versions in my ReadyNas 516, decided to upgrade and redo the box completely. I did have some data on the box when it was a raid 1, but just kept adding drives till I got to four drives. It is currently at the default which I belive is now flex or Raid 5. The software was be upgraded to the latest version.
All this being said I know its hard to figure out which drive is causing the problem, maybe somebody might try to help me
figure this out. My best guess is it is Disk 1, and possibly incrementing Disk 2.
Any Educated guesses on this issue, it takes for ever to resysc a new drive, still want to do this in warrany-
Thanks for any Hekp in Advance. Jeff
Please Note: a bad disk CAN increment an OK disk, at least this is my understanding, look at my VERY OLD post.
Stephen- Thanks Again for all, your help- Things look great here. One Disk replaced completely and resynced, the second at 85% resynced. No Errors, No timeouts.
It took 3 days, 14 hours, 5 minutes to resync the first drive, probably the same for the 2nd.
When you are dealing with 12TB drives....wait!!
I will close this topic, offer thanks and kuddos.

I agree that a failing drive can create spurious command timeouts on other drives - generally because the failing drive is messing up the SATA bus.
Have you tried running a disk test from the volume menu?
Another option is to power down the NAS, and test the drives with Seatools in a Windows PC.

XRAID is the default - not FlexRAID. You can confirm the mode by looking at the XRAID control on the volume page. If there is a green stripe through it, then XRAID is on.
XRAID will use RAID-5 when you have a 4x12TB array.
How do a run a disk test from the Volume menu? I am clueless on this .All I have seen is the ability to hover over each disk and look at it.
I did not get a critical error. The error I showed came up from diagnostics in Raidr. It also showed in the disk area of my downloaded files.
If I was to check the drive with a PC, the procedure whould be shut down the nas. Pull the Drive. Put it on my USB dock. Then Run a seatools program. Which Program? I am hoping I do not have to do this, and wondering if the log files can help diagnose this. Will the seatools progam address the command timeouts, and truly consider the disk bad, not all timeouts are critical- OR NOT.
Thanks for the info
Jeff
Disk 2 Was the last disk to resync. (This just dawned on me)
I never saw a way to test Disks in the Volume Area
