ReadyNAS Data Recovery - VMware recovery tool
Description
This topic contains links to linux VMware images (Debian / Ubuntu) that have been modified to enable you to access your ReadyNAS duo HDDs from any machine with a USB plug and a SATA to USB cable.
Advantages:
* VMware player be downloaded freely
* Can run in both existing linux / MS Windows (XP,Vista etc) operating system without any further modification
Disadvantages:
* Requires a SATA to USB cable
* Mac users will need to find another program to run the VMware files
Background
At some point your ReadyNAS Duo unit is going to stop working (which hopefully will be long and far into in the future) and there may be a point where you'll need to rely on your external backups.
While it's a good strategy to ensure you (and your family / clients) have a good disaster recovery process (having external off-site backups, checking the backups, knowing how to restore from backups etc), in some cases the backups might not work or the backups aren't available to you.
Due to the architecture of the ReadyNAS Duo (more specifically the 16KB blocksize of the partitions), you cannot simply pull out the hard disks, place them into a standard windows / linux pc, then copy all your files across to another computer or storage device.
Unfortunately there are no windows drivers that can properly access the drives and the process to configure a linux pc is complex (see viewtopic.php?f=25&t=24861&hilit=16+blocksize for further background on this)
The following VMware images contain all required patches to read your HDDs in linux just by entering a few terminal commands.
VMplayer Link
To get started, you will need to download a version of VMplayer for your operating system Win/Linux (Mac not directly supported yet), this can be found

VMware Linux Image with Ext2Fuse
acmtn Debian release - tested ok, reports are that it works fine except for files greater than 4GB)
http://www.readynas.com/contributed/dek ... ebian5.zip
acmtn VM login info (username/password): root/rootadmin, vmuser/vmuser1
(please read the forums for more details on how to use this vmware )
_vito Ubuntu release - currently being tested, enables you to use the HDDs directly plugged into your pc without the need for a SATA to usb cable.

Details on this alternative vmware can be found on this post (you'll need to review the instructions carefully):

dekkit Debian release - tested, a number of issues.
my initial attempt that helped start this thread has been found to have quite a few issues and may not work for you, but can be found here if you would like to try:
http://www.readynas.com/contributed/dekkit/VMwareDebian5.0%20-%20ext2Fuse.rar
dekkit VM login info: User: vmplanet pass: vmplanet.net
the acmtn version at this stage appears to be getting more reliable results for users. Unfortunately, I have not had time improve on my original dekkit release due to time constraints but if you would like to try please post your results.
Dekkit release Notes:
* You will need 8GB of free disk space once you have uncompressed the image
* You will still need to execute some of the terminal commands to mount the drive (take precaution so you don't accidently blow away your data)
* This VMware can access other windows file shares and can also be configured to host windows shares (see the docs for debian for more info on this)
* To uncompress the file use WinRar: http://download.cnet.com/WinRAR-32-bit/ ... 07677.html or for non-windows platforms try: http://www.rarlab.com/download.htm
* This image is a work in progress (WIP) so please post all errrors !!!!!.
Dekkit release Usage- this may apply to the other versions (eg acmtn
Login to the OS
Access the terminal and enter the following once the HDD has been attached (take note that your /dev/c may differ):
modprobe fuse
vgscan
vgchange -ay c
mkdir /mnt/lvm
ext2fuse /dev/c/c /mnt/lvm
there is a delay in output but then ..
"/dev/c/c is to be mounted at /mnt/lvm
fuse-ext2 initialized for device: /dev/c/c
block size is 16384"
Dekkit Release Acknowledgements
The original VMware image was found http://www.vmplanet.net/node/85 (before the various patches were applied - so feel free to drop them a donation), if you can improve this image by way of a script to make it even easier to use for us 'non-linux users' then please do so and share it back with the rest of us

- Is there an easy way to tell Rev A or B apart?
I use a Mac OSX 10.6
The colors for the admin page looked different, I don't remember the dark blue colors, although memory can be fickle. I had used that page only once to run fscheck on disks.
Thanks. - I took the disk out to retrive my data. After installing macfuse and fuse-ext and mounting the disk, it shows me the total disk space as 2GB. It's a 1 TB disk. And I only see install software on it, like front view etc. Is there some trick to seeing the remaining data on the disk.
Thanks. - You are seeing the OS partition. I'm not a Mac user, so I can't help on the main issue.
- You will need lvm2
Sounds like your system may have been running RAIDiator 3 or earlier from what you've said.
If you put a spare disk (must not be from your array) and do a factory default and if it manages to complete booting what firmware is it running (don't update the firmware yet)?
Are your disks front loading or top loading?: http://www.readynas.com/forum/viewtopic.php?p=156408#p156408 - Okay thanks. I'll try lvm2.
My disks are top loading. - Are you sure you have a v2 even after reading this article?: 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/
Are you using Flex-RAID RAID-1 or X-RAID? - Hello,
Using a ReadyNAS V1 and Windows 8.1, which vm image would you recommand to recover my data?
My NAS is unavaible. Using Raidar, I can see it stuck in booting, or file checking, it depends. I've tried an OS reinstall (not a full wipe) with no success : now it is stuck in booting, but the IP configuration have been reset (new IP from my DHCP server instead of the fixed IP). So now, I want to recover data, and try to do a full reset then.
Regards, - It doesn't sound like your NAS is dead, so I don't think I'd turn to using the VM just yet.
You may have a bad disk. Have you tried powering down the NAS and checking the disks e.g. using SeaTools if they are SeaGate disks.
Have you tried contacting support? - I have contacted support yes, still no answer for now. I'll check the disk now and see (WD).
Oh and, reinstalling the OS with only one disk (disk 1) on it had taken a lots a time but finally work. For a few minutes I was able to see my NAS again. Could'nt get all the data on it though.
I'm going to check disk 2. If it's all good, could I put it back on the NAS, remove disk 1, and try to boot the NAS with disk 2 ? - Disk 2 pass tests successfully however disk 1 failed !
So i've tried to put only disk 2 on the NAS and boot it. Still no access ? Raidar says "checking file system, 100 %"... I'm waiting a few hours to see if the NAS finally comes up, maybe it needs a resync or something, but I'm surprised I still cannot access it.
