ReadyNAS 314 Data Missing after Reboot

[Cedllau]

Everything is normal before it became unsearchable in the network.

Then I shut down the NAS by pressing the power button.

After power on the NAS, it still can't search in the network.

So I installed the RaiDar to find it.

The software showed me the Status: Volume data-0: RAID Level 5. inactive: 0MB (0%) of 0MB used.

What should I do now? I don't know how to recover my workspace's NAS.

And there is not IT department in my company.

Contact paid Netgear support (using my.netgear.com).  You don't want the gearhead support.  I suggest using per-incident support for this - as it often can be easily fixed.  However, it could end up needing data recovery.  https://kb.netgear.com/69/ReadyNAS-Data-Recovery-Diagnostics-Scope-of-Service

If you have trouble finding the per-incident support option, you can send a private message (PM) to @JohnCM_S or @Marc_V using the envelope icon in the upper right of the forum page.

When you get your data back, you should

1. Put a backup plan in place for your NAS - RAID is not enough to keep it safe.  USB backup drives are a cost-effective option.
2. Upgrade your firmware - it is five years old, and very out-of-date.  You should be using 6.9.6 (current "long term support" firmware), or 6.10.3 (current "stable" firmware).
