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.

Well, stop manipulating disks and look into data recovery.

Netgear offers a service: https://kb.netgear.com/69/ReadyNAS-Data-Recovery-Diagnostics-Scope-of-Service If you can connect all the disks to a Windows PC (USB adapters/dock is ok), then you could try ReclaiMe: https://www.reclaime.com/

Thanks Sandshark,

I did swap the right drives, but made (now in hindsight) many mistakes. Like not backing up, swaping disks while the unit was running, got too confident that's OK after the first swap worked and checked and after, rebootng twice, was fine. I assume that's what get's us as a specie in trouble - overconfidence in things that we don't really understand

All I wanted was to get rid of that "degraded" thing that appearead after I tried a brand new new 8TB Western Red (that was unknowingly to me bad - again, I should have checked on my PC, but did not.

Followed Stephan's instructioI, bought an icident and a year of call support, because after this I ploan to change to the 10TB Seagate4 enterprise that are now very affordable and put the unit in a raid 6 this time.

So right now I just put the machine in tech suport mode, and opened a case support.

The confusing thing was "healthy disks" (which aparrently on hoovering in the WebUI NAS icon were not). So by trying to fix the "degraded" state i got in "dead" state, emboldened by appaent initial success.
