Hi rvijay26,

Based on the logs, disk 4 most likely failed while the new disk 2 is still syncing which is why the volume failed.

It will be best for you to contact NETGEAR Support so they can assist you in recovering your data (https://kb.netgear.com/69/ReadyNAS-Data-Recovery-Diagnostics-Scope-of-Service).

Thanks for your reply! While that does seem like the most likey scenario, I am a bit puzzled because this exact thing seems to have happened to other users. I never got any error messages relating to drive 4 but just when I was resyncing drive 2 , it decides to go bad.

I am in touch with Netgear support and they will be advising me on further steps. I will post an update once I have some solution from them.

Meanwhile, I am wondering if the following reasoning makes sense:

Assuming drive 4 has gone bad but since my original disk 2 is not yet been declared bad, I might be able to recover some data using disk 1, old disk 2 and disk 3 .

I am not sure if the resync operation affected disk 1 and disk 3 as well.

Is there a way to clone these disks and play around with the clones?

You can clone the original disks to new ones using any tool that does sector-by-sector copying. Clonezilla is one of several.

The disks are likely to be out of sync though, so you might need to forcibly mount the RAID volume. Damage to the file system can include errored blocks on the disks, but also includes inconsistencies that result from the out-of-sync array.
