Failed to activate encrypted volume
Hello. For a long time I've been runnning my readynas on a single disk using the build in encryption. I felt it was time to change the drive and decided at the same time also add a bit of safety so I...
Hi, yes. I've tried copying over the key multiple times to the USB. Even tried renaming it to data-0.key instead of data.key due to ReadyNAS now reporting the drives name as "data-0"
I used the disk just prior to swapping to the new drives so the health should be good.

It's calling it that because it's not able to mount it. No need to rename the key.
Was the NAS powered down when you removed the drive?
Maybe download the log zip file, and see if there is more information in there on what's going on.
Ah, good to know! Thanks. Yes it was powered off.
data-0 is the name of the first layer of the MDADM array containing BTRFS volume data. If expansion adds a second layer, it's data-1. So, the error you are seeing says the NAS does not recognize the BTRFS file system for your volume but does recognize the MDADM RAID array. I don't use encryption, so don't know if that's driving it or not. In cases not involving encryption, it is a bad sign usually indicating a damaged array.
This was a single-disk JBOD volume, so the volume couldn't have been expanded.

Me either, but if you decrypt a virtual disk with the wrong key you certainly won't detect any file system.
If you decrypt a damaged volume with the correct key there might be some evidence of damage in the logs.
Either way, it's not good.
