Here's what I have done so farI have a readynas NVIt has 4x1TB (xraid) 4.1.61) I bought 4 new 2TB drives2) Replaced each drive one at a time3) Rebuilt successfully after each drive replacement4) RAID begun expansion after 4th drive was put in.5) Never properly expanded6) Found out I had the wrong block size so, I would need to do a factory reset (a very old device)7) Backed up ALL data to external hard drives8) Factory reset9) Rebuilt okay10) Restored old config11) Became unresponsive12) Factory reset again -- unresponsive -- says root corrupted13) USB reset -- looks like it works.14) reboot, I get two LEDs blink, then four LEDs, then two, etc...15) check dimm -- seated okay15) try tFTP reset -- loads up okay16) upon reboot, it never comes back up.17) reboot, I get two LEDs blink, then four LEDs, then two, etc...18) USB reset -- looks like it works.19) reboot, I get two LEDs blink, then four LEDs, then two, etc...Please help. These are new drives, and work fine outside of the NAS with no problems. I'm at ends wit!Thanks,Eric

According to this document it means "Corrupted, do not mix used disks and cold boot up. In most cases, problem may be solved by OS reinstall with optional NAND recovery. Contact tech support before taking actions."http://www.readynas.com/download/docume ... AS-LED.pdfWhen you backed up the config, which version of firmware were you running? If the configuration settings are from an older version of firmware, this may be related to the problem.My advice would be this:1. Check each disk using vendor tools to confirm that they are okay:faq.php#How_can_I_verify_that_my_disk_is_bad%3F2. While installed in PC, delete any/all partitions that may be on the disks.3. Install one disk only in the NAS and perform a factory default (use USB/TFTP boot recovery, if required).4. If the config settings are for the same version of firmware, restore the settings. Otherwise, you may want to manually recreate the desired settings.5. Reboot and verify that all is working as expected. If so, proceed to hot-add each remaining disk (one-at-a-time) and wait for the process to complete before adding the next drive.6. Upon successful addition of all disks, reboot again, verify expected functionality and restore data.-Dave

I've gotten to step 3, and performed the factory default (TFTP), however I'm still gettting corrupt root -- and I've tried this with a couple of disks. What next?

OK. This time the factory reset seems to have worked -- really I tried the exact same thing a number of times.I did it with just one drive, and it came up quickly. I've added a second drive, and that's currently resynching. Once this is done, then I'll do the third and fourth. I hope it all works this time.

It's currently expanding to the third disk...Configuration: X-RAID (Expandable RAID), 2 disks Status: Initializing 7% complete, Time to finish 8 hr 59 minSo far, so good, but I've been here before. I've got my fingers crossed!-Eric

So, the technician, remotely accessed my unit, and I had just rebuilt the 4x2TB XRAID array, and he logged onto it and found this:
"We have remotely logged into your device and checked the integrity of the system. The device shows no improper shut down events and there currently is no evidence of the root file system being corrupted."

So, I then rebooted the device from maintenance mode (TELNET in RAIDar), and sure enough it came up "Corrupt root"

The tech then, got back on the device and found this:
"After looking into your device I see an error with the unit mounting the volume after a successful XRAID start. In this case the issue resides with the device hardware, as such there is nothing further we will be able to do. The final option is replace the hardware. Unfortunately this device falls outside hardware warranty therefore we will be unable to replace it."

Funny how everything now works 100% as a XRAID 4x1TB (spent ~7hrs working on this today). I can't believe I'm still dealing with this after more than a month. Clearly there is an issue with the software that needs to be fixed.

Can anyone from Netgear help me out here?

ps. I've also tried four other sticks of memory (even though the one in there worked fine for the past 4 years).

Did you ever get this fixed? I was wondering if your 2TB drives worked OK if you did?

chesirecat1 that is completely off topic. Have a look at http://www.readynas.com/hcl

Any drive on the list is approved for use. If not on the list then it is not approved for use.

I only ask here because that's the drive the OP had. The list is useful, but it does not include discontinued drive models that may have once been on it. This thread is the only search result for that model number and it's missing the usual discussion as to whether or not the drive is compatible.

The drive may/may not work. If you have issues with it, support will be denied.

If a drive is added to the list it is not removed simply because the drive is discontinued. It's likely the drive you mention was never added to the list in the first place.
