That's not one of the routers covered on this section.

While many questions about routers are generic and could be answered anywhere, some things need specialist knowledge.

You might get more help, and find earlier questions and answers specific to your device, in the appropriate section for your hardware. That's probably here:

ReadyNAS Network Storage: Official NETGEAR Community

You might like to search there for messages related to your problem.

I will ask the Netgear moderator to move your message.

In the meantime you could visit the support pages:

Support | NETGEAR

Feed in your model number and check the documentation for your hardware. Look at the label on the device for the model number.

Check for various troubleshooting tips.

You may have done this already. I can't tell from your message.

I mention it because Netgear stopped supplying printed manuals and CD versions some years ago and people sometimes miss the downloads.

I search about solution and i find reply that i need to use command ( btrfs rescue) but i run it with windows 10

Note : the issue happened case of disconnect the power or remove the desk once the server is running )

Then you likely need to forcibly assemble the RAID array with mdadm (and not use btrfs rescue).

You'd need to enable ssh on the NAS, and then access the NAS by entering ssh root@nas-ip-address in the windows search bar on the NAS.  Do you have any experience with the windows command line?
