ReadyNAS NV+ blinking blue and green LEDs
My ReadyNAS NV+ has developed a fault. The blue power LED is flashing at inverals of about once per second, and one of the two HD LEDs is flashing at the same rate.
I can ping the ReadyNAS, but I can't access it via a browser or RAIDar. Unfortunately I can't read the LED panel because cables from a replacement power supply are pressing against the back of it which garbles the output (though not always, oddly).
I believe the flashing HD LED is telling me that the second X-RAID mirrored drive has failed. The two disks are a pair of 1TB drives.
I bought two WD Red 2TB NAS drives in anticipation of a future failure back at the beginning of the year, but I see now that they are "SMR" drives, which appear to be controversial.
I would simply pull out the failed drive, but since the ReadyNAS is not responding to RAIDar / browser access I'm not sure what the best course of action might be. Ditto for the suitability of the replacement drives.
I'd be very grateful for any advice.

Assuming I go down this route and acquire another 1TB drive, is it best to leave the ReadyNAS powered on with the existing drive connected when I plug it in the new drive to begin the RAID creation process?
I do recommend doing a hot-insert (with the NAS running). The benefit of doing a hot-insert or a hot-swap is that the NAS detects exactly what is happening. If you do it with the NAS powered down, then it needs to figure out what changed.
Though doing it powered down generally does work too.

That is the usual sign for a failed drive. But something more is going on since you can't get status from RAIDar.
I'm assuming the two drives are the only ones you have installed, since you don't mention any others.
Your best course of action is to test each of the drives using a PC and manufacture's drive test tool. If that is not an option, you could try booting with each drive individually.
You are correct the SMR drives are not the best choice for RAID. However, the file system of your older NAS will put up with it better than the BTRFS used on current ReadyNAS, though re-sync time will be affected.
Thank you very much for replying. My apologies, I should have clarified that the ReadyNAS has only two disks installed, both of 1TB capacity.
I also have an external drive connected to the ReadyNAS, and a nightly backup keeps the content synced.
I could try sourcing drive test tools for the disks. Currently I don't even remember what make and model they are.
Regarding booting from the drives, forgive my ignorance, but do you mean taking them out of the ReadyNAS and connecting them to my PC, and then booting from each drive from there? Or removing each drive in turn from the ReadyNAS, and then attempting to restart it?
I appreciate the note about SMR drives, I wish I'd done more research at the time, but perhaps I can make do with these ones. I'm not worried about performance, the ReadyNAS isn't used intensively. I just want it to be reliable.

Removing each drive in turn from the ReadyNAS (powered down), anad then powering it up.
It's fine to keep the disks in there current slots (trying to boot up with disk 2 in slot 2, and slot 1 empty).
