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...

1 - What do I do once I connect the drive? What is the goal? What am I looking for?
First, run the short test on each drive. If that passes, follow it up with the long test.
The goal is just to make sure all the drives are healthy.

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?
That is an option if you power down the NAS when you remove/replace drives. 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.

3 - For my own education, how can a drive failure or corruption take down the entire NAS?
There are several scenarios. One is that you might have more than one failed (or failing) 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.

I have tested my drive 6 with the WD Dashboard and it is giving a SMART error:
"Failed with error code: 4"
I have ordered a new 6 TB WD Red drive to replace this failed Drive 6. I assume I can just hot install the new drive once it arrives and all my data on the NAS has been backed up? I do not plan to ever power down the NAS if I can avoid it.I'm glad you are running again. I suggest using one of the NAS as a backup of the other after you sort through all this.
Also, there are maintenance tasks on the volume settings wheel that you can schedule. I run one each month (cycling through all four 3x a year).

Yes. Make sure you get a WD Red Plus (or a Seagate Ironwolf). The WD Red (WD60EFAX) is an SMR drive (Shingled magnetic recording), and not a good option for ReadyNAS. (Your older WD60EFRX are CMR, so not a problem).
- The backup is currently running, I have set up a scheduled RSYNC job to run once a week to copy all the files from NAS1 to NAS2. The copy is still running but I have verified that many new files already exist on NAS2.
I do not plan to make any changes until the backup is complete. I have also already placed an order for a new replacement hard drive.
This is what I ordered “Western Digital 6TB WD Red Plus NAS Internal Hard Drive HDD - 5400 RPM, SATA 6 Gb/s, CMR, 256 MB Cache, 3.5" -WD60EFPX”
When it arrives and the backup is complete, I plan to remove the drive tray from the old failed drive and attack it to the new drive and then while NAS1 is up and running, insert it into the chassis.
