These particular errors are detected by the drive itself, and I don't see any way that the NAS firmware can create them, no matter what ATA commands it issues.

The equivalent WD disk is the WD30EFRX (which is what I prefer). DM drives are known to be trouble-prone (for instance https://www.backblaze.com/blog/3tb-hard-drive-failure/ )

Detected increasing uncorrectable error count:

I have two RN104 devices, both with 4 drives of 3TB Seagate Barracudas.

A week ago I got a error similar to this on Unit 1 -- DISK 4

Today I saw this error on Unit 2 --- DISK 4

Coincidence or is there an issue with the NAS system??

Hi MWilliams4,

Drive failures can happen anytime and to be sure if the drive is faulty and needs to be replaced, kindly check this page for instructions.

    Swapped out two more drives, one on each, and both within a week are giving the same errors.
    
    Something is wrong...and from reading the article, I guess it's my seagate 3TB's UGH
