I would have refrained from doing and OS reinstall until you knew exactly the cause of the issue. An OS reinstall clears the logs, so we won't have any way to troubleshoot the problem to find out the initial cause. What was the purpose of doing a TFTP recovery? Did you TFTP recover ReadyNAS 3.x firmware or did you TFTP 4.x? If you were on 4.x, and downgraded to 3.x, it is possible you ruined your volume and would need to start over. The cause is probably a bad disk that was preventing it from booting to begin with; you indicated disk 4 was blinking... I would have started by turning off the device, pulling disk 4, and then rebooting the device to see if it starts. I would highly recommend calling into support to see if there is anything they'll be able to do to assist you with your device.

I did those things too. Tried booting it with any one disk out, but it was the same. Googling it the disk 4 + led combo seems quite common, so don't think it's necessarily related to disk 4. I had a few ATA errors on disk 3 (less than 50).

We'll see if the 3.x downgrade killed the volume, then I'll just bin it, have a couple of Ultra/Pro 6 units as well, but have some none-critical files I'd like to recover from this device if possible.
