ReadyNas Ultra 6 Stuck on Boot – NOT NAS Hardware – Other Drives From Second NAS Work Fine
Let me start by saying I do not know almost anything about the recovery procedures. I am fairly technical but am not familiar with how to recover a NAS. I have browsed this forum but I have adv...

You won't need that, since you already now the problem is not the NAS.

What should I try next to get it back?
I suggest starting by connecting the NAS 1 disks (one at a time) to a Windows PC, and testing them with the vendor tools (dashboard for Western Digital, Seatools for Seagate). Windows won't recognize the file format, but the tools should still find the disks. You can connect them using a USB adapter/dock.
- Thank you. I have exactly what you are describing. A drive adapter that powers the SATA drive and also converts the data to USB to connect to a PC.
I understand that windows will not be able to use the file system on the drive. These are WD RED drives. So I guess I need to download the “Dashboard” tool you mentioned.
My questions are the following:
1 - What do I do once I connect the drive? What is the goal? What am I looking for?
2 - Can I not just take one drive at a time out of NAS1 and then power it up and see if it comes up? If not put that drive back in and see if the next drive removed allows it to come up?
3 - For my own education, how can a drive failure or corruption take down the entire NAS? Isn’t that exactly what it’s designed to avoid happening? What causes a bad drive or bad drive data to lock up a NAS so nothing at all comes up? Not even the network interface?
Thanks for your patience and helping me understand.

The goal is just to make sure all the drives are healthy.

If the NAS does come up,. then offload the data before you do anything else. Don't write anything to the NAS, and don't replace the missing disk.

Failing disks can sometimes lock up the SATA bus. The drive might also be timing out on every read command, which would make the boot process glacially slow.
It is back up! This is what I did:
- I powered down the NAS1
- I removed Drive 1 from NAS1
- I powered back up NAS1
- The problem still existed
- I powered down the NAS1
- I re-inserted Drive 1 into NAS1
- I removed Drive 2 from NAS1
- I powered back up NAS1
- The problem still existed
- I repeated each of the above steps for ALL 6 drives
- Finally on the very last drive, Drive 6, NAS1 came up!!!!
I am noy doing an RSYNC between NAS1 and NAS2 to get the data off the NAS1 as fast as possible.
Once I get everything backed up, what should I do to get all 6 drives working? I will test Drive 6 via the method you talked about with the WD tool. If the drive looks ok, do I put it back in? Should I just get another 6 TB WD Red and use that instead? I have the RAID setup as a RAID 6.
