RN316 soaped one drive and all volume is unreadable and HDD's are in red
I wanted to exchange the HDD's, because it showed degraded, but I had access to all the data.
In theprocess, I put a brand new WD RED 8TB, that prooved to be defective and I RMA-ed it.
I put it ...
A degraded volkume with all "healthy" drives usually means the volume is out of sync. Until it's back to healthy, replacing a drive is not a good idea and replacing anything except the one that's out of sync is a disaster.
I'm not sure if you did actually replace the wrong drive at one point or if the (quite drive intensive) sync process pushed another drive over the cliff, but I agree it sounds like you are in file recovery territory.
soaped=swaped...
long sleepless night..
Do I need to activate remote access to the server for troubleshooying?
You might want to adjust the size of your signature.
You can try cloning the two suspect drives to new ones (using sector by sector cloning).
From there you can recover data by
- using Netgear's data recovery service: https://kb.netgear.com/69/ReadyNAS-Data-Recovery-Diagnostics-Scope-of-Service
- connecting all the hard drives to a Windows PC (likely using a USB adapter/dock) and then use ReclaiMe software. https://www.reclaime.com/
- attempting to recover the data yourself (if you have the linux skills).

I was noticing tha HDD1 (old WD RE 2TB) was showing ATA error 14 ( no ideea what that means, all the smart tables I found go to 13 the jump in the hundreds, so I had two Seagate desktops 4TB laying around, and I thoought I will change with them
First of all, you can't replace disks when the volume is degraded. That's the step that did the damage. When you replace a disk, the system uses RAID parity to reconstruct the data on the new drive from the others. That requires that the RAID array be redundant. If it's not the volume fails (as you found).
As far as ATA errors go, these aren't really SMART errors. The NAS itself reports them when the NAS SATA controller can't communicate with the disks. https://kb.netgear.com/19392/ATA-errors-increasing-on-disk-s-in-ReadyNAS
