Hello, it is the 3rd disk that is disabled. The disks are working normally and out of nowhere, they show up as disabled and I have to change the disk to remount my shared folders. I need help, I'm putting the log files in the post Thanks.

Failed password for invalid user ftpuser from 13.94.255.171 port 53232 ssh2

Are you directly forwarding the port for FTP and/or have the server in your router's DMZ?  Not the greatest idea as eventually a brute force attack (which is currently happening) will eventually succeed.  Use a VPN or reverse proxy or the like.

By and large drive failures are exceedingly rare

 

This

Nov 12 16:08:23 unRaid-DINO kernel: ata3.00: failed command: READ DMA EXT

implies that you've got poor cabling (loose sata and/or power -> SATA connections are (pardon my French) shit, especially if you ever add in splitters etc into the equation)  Now, seeing as how the drive in question is returning no SMART data at all it is either

1. The above problem (that code snip however was from your parity drive)
2. The drive actually is completely dead

 

#1 is far far more likely.  Reseat all the cabling (both ends), and after you've done one drive, make sure you don't touch it (and hold your breath) when doing the next drive.  Additionally, if you problems seem to be always on Disk 2, then do NOT use locking SATA cables.  Most of them actually do not meet spec on the requirements and hold worse on WD drives than the non-locking type (which by definition ARE spec)

Also look in the BIOS for an AHCI option for the SATA controller, if there isn't one look for a RAID option.
