Netgear ReadyNAS Duo v1 salvage operation
Short version: I have a 3TB disk with all my data, that only my old ReadyNAS can access. Right now I can't access it through the ReadyNAS either, cause unknown. I want to keep the data, and avoid a format if possible. I need help either fixing the ReadyNAS device so it will read the disc correctly OR access the disc with my data some other way that through the ReadyNAS.
Long version: I've recently gotten a new NAS device, upgrading my ~3 year old ReadyNAS Duo to another 2bay NAS. My harddrives are 2x Seagate 3TB NAS drives, none of which has ever been in any raid config. I'm using a HP Probook laptop running Win8 with all relevant software updated. At the moment I don't have access to a desktop rig to try to collect the data that way.
Disk 1 has only been installed in the ReadyNAS and contains all my backup data.
Disk 2 has only been installed in the new NAS and contains no data.
I suspect that the ReadyNAS is somehow failing, while the hard drives are most likely OK.
My problem is that my ReadyNAS does'nt work properly, and it's seemingly the only device I have able to access the data on Disk 1 (atleast when the ReadyNAS is functioning properly). This is likely because of the ReadyNAS formatting the drive upon installation, which implements a partition system my other devices won't recognize. Not even my WD external harddrive "shell", which originally had a 1TB drive in it, will allow me to access it. The disc manager tool in windows detects the disc, which holds about 3-4 partitions but with no (recognized) file system.
With Disk 1 inserted in the ReadyNAS and turned on, I can locate it using both RAIDar and windows explorer. (I find it odd though, that win explorer lists the NAS twice in explorer - one using the NAS IP address and one using the Netgear-style Host name.) I can however only access the root folder of the drive, containing the default Netgear folder Media and Backup. When trying to enter any of the folders in the root directory, I get the standard windows timing out "cannot access 10.10.0.999/media" file/destination error message. This happens when the drive is installed in either one of bay 1 or bay 2.
The problem started a while back, when I suddenly was unable to turn the ReadyNAS off the normal way - I ended up having to pull the power cord to kill it. Since then I've been unable to access the data on the disc.
Any guidance is appreciated.

- If it was the disk in slot 1 of the duo and the disk is not faulty then you should be able to read it using this, which needs to be installed on a PC. The drive obviously will need to be connected to the PC, perhaps with a USB caddy.

If you get hold of the data, make sure you have a backup plan in the future. - Hofmann, if you have been using 3 TB disks then you must have a Duo v2 or an ultra/pro 2. If so, linux-reader won't work (so don't try vandermerwe's suggestion right now).
Can you check this guide? http://www.rnasguide.com/2012/01/09/how ... -or-nv-v2/ You can also copy the model number off the label (something like RND2000-200) and tell us what that is.
Your NAS uses the linux ext file system. The data volume is also formatted as ext, but its built on top of RAID, Windows won't access it. FYI, Windows won't see any partitions from any NAS that is built on linux. Almost all of them are. - I have just noticed that your disk was not in Raid, did you have it set as jbod?
The 2 3tb drives, are those new drives for your new nas or are these the ones from the duo?
I am not sure if linux reader would not work, it works with the sparc units but does not seem to work with the intel units.
I'm not sure about the duo v2, perhaps StephenB has tried it. StephenB wrote: Hofmann, if you have been using 3 TB disks then you must have a Duo v2 or an ultra/pro 2. If so, linux-reader won't work (so don't try vandermerwe's suggestion right now).

I'm positive that my NAS is a v1, it's atleast 3-4 years old and identical to the v1 layout portrayed in your linked guide. The discs are just a few months old, and only one of them ( "disc 1" ) has ever been insterted into the ReadyNAS. This is also the only disc containing the data i want to salvage.vandermerwe wrote: I have just noticed that your disk was not in Raid, did you have it set as jbod?

I've never set up RAID on these discs, basicaly just plug and play so i take it that they end up as JBOD this way.
Caddy? No, i drive a Volkswagen.vandermerwe wrote: perhaps with a USB caddy.
/golfclap- I don't think you having anything to lose by trying linux reader.
Agreed. Though its not clear it would work either. Linux Reader only works on disk-1 of the duo v1, it wouldn't work on any other 2-bay ReadyNAS. And in this case disk 1 was a 3 TB drive, which the v1 NAS would treat as a different size.vandermerwe wrote: I don't think you having anything to lose by trying linux reader.
Hoffman - if you just plugged two drives in the NAS, then it would set up RAID-1 - that is the default.
The V1 NAS doesn't support 3 TB disks, it is limited to 2 TB. If you in fact have a V1 with 3 TB drives, you would have ended up with ~768 GB of space in a RAID-1 array - wasting > 2 TB of space. Linux Reader mightbe able to read disk-1 in that case, but it wouldn't read disk 2.
If you know you had a 3 TB volume before, then you either have a duo v2, an ultra-2, or a pro-2. You've already ruled out the duo v2, but the other two are still possibilities. A duo v1 would have an RND2000-100 label, the pro or ultra would have something else. There's a list of model numbers here: viewtopic.php?f=10&t=59892#p336358- You're right, it is a v2. RND2000 v2. But the layout of the back is sill identical with the depicted v1 model in the beforementioned link.
If so, it should be able to handle 3TB discs. Remember, i've only ever had 1 of my 2 3TB discs in the readyNAS. I'll try the linuxreader when i get home tonight.
If you read through the guide, you will realize that the model names are misleading, so you need to be very careful on this. If there is a -100 after the RND2000 you have a v1. If there is a -200, you have a v2.Hofmann wrote: You're right, it is a v2. RND2000 v2. But the layout of the back is sill identical with the depicted v1 model in the beforementioned link.

The v2 you are seeing might not mean what you think it does. On the rear label, it is a hardware revision code - it is not the platform type.
The v2 units were introduced in Nov 2011 and there were both models available for a bit, so "3-4 years old" could be either one.
Checked both the back label and this one, underneath it, neither one has any -100 or -200 in the model names- If the rear shows the v1 layout then it is a v1.
That sticker at the bottom would indicate it is a v1 hardware revision 2.
