Ready NAS 102 in accessible (corrupt root)

Question

Netgear Community:&nbsp;I have been using a ReadyNAS DUO V2 device with a single WDC WD20EFRX 2TB HDD without issue.&nbsp;At this time, the device is not accessible, does not register as being on my home network.&nbsp;As of November 24, I found the device inaccessible, and have been looking for answers.&nbsp;With the help of RAIDar 6.2 (for Windows), I see I have a "Status: &nbsp;corrupt root", the "Firmware" is *blank*, the IP address is shown, and the single drive installed in the device shows with a green check mark, and a capacity of about 1863GB.&nbsp;I attempted an "OS reinstall" prior to finding RAIDar and the fact that the LEDs were controlled by the "Backup" button suggest the enclosure itself is operable.&nbsp;I have seen the reference for a "USB recovery" along with the cautions that this ONLY be initiated through Netgear support.&nbsp;My questions are:&nbsp;1. &nbsp;Is the content of the HDD presumed to be intact (based on the green check mark of RAIDar)?2. &nbsp;Can &gt;this&lt; HDD be loaded into another, newer (current) Netgear product, and have its content intact and accessible?3. &nbsp;Can the HDD be accessed *outside* of the ReadyNAS enclosure?4. &nbsp;If I purchase and install a NEW, unitialized HDD, would that achieve a recovery, such that I could return the current disk to Bay 1, then initiate a RAID operation to the *new* disk in Bay 2?5. &nbsp;Can the USB recovery process be executed WITHOUT having a HDD installed in the ReadyNAS device?&nbsp;Thanks in advance for your helpful replies.&nbsp;&nbsp;

First, please confirm that your ReadyNAS is a v2. &nbsp;The labels can be confusing, so please use this guide:&nbsp;http://www.rnasguide.com/2012/01/09/how-to-tell-whether-i-have-a-duo-v1-or-duo-v2-or-nv-v1-or-nv-v2/

1. &nbsp;Is the content of the HDD presumed to be intact (based on the green check mark of RAIDar)?
&nbsp;
&nbsp;

No. &nbsp;Corrupt root means the OS partition on the disk is corrupted. &nbsp;The data might be corrupted as well.

2. &nbsp;Can &gt;this&lt; HDD be loaded into another, newer (current) Netgear product, and have its content intact and accessible?
&nbsp;

Perhaps, though it likely will need an assist from support. &nbsp;http://kb.netgear.com/app/answers/detail/a_id/29876

&nbsp;

Yes. &nbsp;R-linux for windows is worth a try.

No.

&nbsp;

Not sure, but I don't that helps you. &nbsp;Corrupt root is an issue with the disk.

Hi StephenB.&nbsp;Thanks for your post.&nbsp;Based on the back panel layout and front cover featuring the explicit label "ReadyNAS DUO v2", I'm reasonably confident I &gt;do&lt; have the V2 product.&nbsp;I downloaded an evaluation copy of &nbsp;R-Linux (R-Tools?) but it wasn't able to see the NAS device on the network. &nbsp;Do I need to place the HDD in a USB enclosure, attach that directly to the PC with this product?&nbsp;My question about USB recovery *without* the HDD installed is to perserve the contents/state of the HDD.&nbsp;All paths seem to point to Netgear Support to have them weigh in as well.&nbsp;Thanks again.&nbsp;

Yes, and that'd be true with all similar products - the NAS isn't booting after all.

&nbsp;

Understood. &nbsp;But the problem is with the OS partition on the HDD, and USB recovery won't help that.

USB Boot Recovery requires booting off a compatible USB key. It wipes the internal flash and puts a clean copy of the firmware on it. The disks neither need to be installed to run USB Boot Recovery, nor do they need to be removed.USB Boot Recovery&nbsp;will only help if the firmware on the flash is corrupt. As StephenB mentioned it's not going to help with this problem.

Thanks for your insightful, helpful contributions.&nbsp;As I type, the HDD in question is being scanned by "linux-reader" from DiskInternals. &nbsp;I was able to "install" the HDD from the ReadyNAS into a (powered) USB enclosure, then connect that to a Windows 10 PC.&nbsp;It was a small relief to see that this facility quickly identified the WDC HDD, along with its "partitions". &nbsp;It also advised that the RAID was "damaged" but "recovery was possible". &nbsp;That led to downloading another component (which appears to require a license) called "RAID recovery". &nbsp;At the moment, the HDD is being scanned, finding folders and files. &nbsp;I expect this process to take hours (possibly days?).&nbsp;All this *suggests* that the content is accessible, that the disk is not entirely damaged.&nbsp;This leads me to ask whether a true RAID (2 physical devices, 1 a mirror of the other) would have been impacted by whatever phenomenon led to the "corrupt root" condition. &nbsp;Plainly, is the RAID protection restricted to the "content only" portion of the HDD?&nbsp;I have no issue with this Netgear product which has worked (and seems to continue to work) long after its purchase (and warranty expiration).&nbsp;Presuming I am able to recover the contents from this "corrupt" device, could it safely be reformatted? &nbsp;I appreciate that there's really no way to be sure; that's more asking for an opinion. &nbsp;I'll have to purchase new storage devices anyway, and since there's no apparent "upgrade path", probably a new NAS device. &nbsp;Is there a logical upgrade from the ReadyNAS DUO v2?&nbsp;Thanks again.
