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...

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.
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).
Thank you StephenB for the detailed explanation, I will try that now and then reply with my results.
Edit: it's refusing to respond to holding down the power button for 5 seconds. So I'm resorting to a power button switch off.
Update. OK, I removed the disk from slot 1, and left the disk in slot 2 connected, then powered the device back on.
Helpfully the LCD display is readable, and after spending several moments saying only "booting..." it now says:
"booting... Found bad disk"
So that seems to confirm it. What's the best sequence for moving forward from here (of reinserting disks / device powered off / on when doing so)? I am a bit concerned about this SMR scenario. The dead drive is a Seagate Barracuda 1TB with model number (I think) ST31000520AS. The second drive is a WD Red 1TB WD10EFRX.
Thank you again

Does it boot up normally with disk 1 in slot 1 (and slot 2 empty)?
I am a bit concerned about this SMR scenario. The dead drive is a Seagate Barracuda 1TB with model number (I think) ST31000520AS. The second drive is a WD Red 1TB WD10EFRX.The WD10EFRX is CMR. I believe the ST31000520AS is too old to be SMR. Plus 1 TB Barracudas are listed as CMR here: https://www.seagate.com/internal-hard-drives/cmr-smr-list/
WD RED Plus drives are all CMR, as are Seagate Ironwolf drives. I'd avoid desktop drives, and WD Reds.
Thanks again. When I removed drive 2, reinserted drive 1 and then restarted, the device LCD said that it was running a "quota chk" which took several minutes. Unfortunatly the display became garbled again when it was nearing the completion of this. However I am now able to access the ReadyNAS via my browser.
The Health panel shows:
Disk 1 WDC WD10EFRX-68JCSN0 931 GB , 28 C / 82 F , Write-cache ON OK
Disk 2 UNKNOWN 931 GB Dead
Fan 1 1875 RPM OK
Temp 1 31.5 C / 88 F [Normal 0-60 C / 32-140 F] OK
UPS 1 Not present OKOddly the log shows relatively little information:
Mon Dec 7 00:43:13 GMT 2020 System is up.
Mon Dec 7 00:37:09 GMT 2020 Improper shutdown detected. To ensure data integrity, a filesystem check should be performed by rebooting the NAS through Frontview with the volume scan option enabled.
Sun Dec 6 00:31:41 GMT 2020 Backup finished. [Job 001]
Sat Dec 5 11:02:53 GMT 2020 UPS is on line power.
Sat Dec 5 11:02:47 GMT 2020 UPS is on battery power.Also, my fault again for ambiguity. The drive specs I mentioned previously were for the existing drives inside the device. The two replacement drives that I purchased for future use are the WD Red variety with SMR.
