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

I've been following this thread and I've managed to get the Debian image up and running before running into the

It seems _vito was able to overcome this issue with version 0.5 of ext2fuse. Unfortunately, my linux skills arent sufficient to sort this out.
Can someone post the steps required download/recompile this?
Thanks - any help is very much appreciated!

A few people have successfully managed to successfully install and setup their own (eg redbrick one sounds like he has built the ultimate one) without the issues described above. I'm in the process of trying to find time to install one from scratch at the moment as there were issues with uploading the redbrick version.
If anyone has has one hosted on a private ftp please msg me the details so i can download and put it onto a public site. - _vitoAspirant

Yes I did and now I finished copying my data.
I tried also to make another version with alternate ubuntu, but I unsuccessful (me neither linux expert...) and resign.
Let me just clean the working version and switch back it to english (or you can read italian?) then I will share it.
Only one problem, the version did not work with large file size like DVD images (about 5 Giga).
A couple of days... - mdgm-ntgrNETGEAR Employee Retired

:( I have lots of files greater than 5GB in size. Oh well, it's better than nothing. Hopefully over time data recovery will get better. I don't need it at the moment, but it's nice to have available just in case. - _vitoAspirant
mdgm wrote:

Me too, they are iso created from my DVD collection... it means that I have to copy them again. Anyway I save one of the disks, maybe in future I could recover with a newer VM.
Besides, I finished to clean up the my almost-working VM and I put it on rapishare.
IMPORTANT:
- I AM NOT A LINUX EXPERT, the VM worked with MY PC CONFIGURATION, USE IT AT YOUR OWN RISK!
- I connected the disk to PC SATA controller (no USB) and added it to VM as physical disk (see reade me file inside archive)
- due to SATA disk detach (so you also can try it on your own PC) virtual disk /dev/sdb1 was renamed to /dev/sda1, so I think it will not boot in graphical mode; I added some very simple instruction to tell which is boot-disk and reboot (see reade me file inside archive); please tell me if you know how to fix this issue permanently
- on VM desktop there is another HOWTO file which explain step by step what to do (very detaliled and for low level user).
- again I was NOT ABLE to recover big files (several GB), don't know which is maximum size recoverable

Please give me your feedback for improving it. - dekkitAspirant
- I AM NOT A LINUX EXPERT, the VM worked with MY PC CONFIGURATION, USE IT AT YOUR OWN RISK!
It would appear that we are all Linux newbies :) however as a collective we're getting closer to getting workable solutions. Thank you for sharing this, i'll download and store it more permanently next to the one i did.
if anyone else has created their own vmware image, please share! - acmtnAspirantI have an image that I just built using Debian 5.03 and VM Workstation 7 (thanks for all the postings - very helpful). I built it after getting tired of waiting around for 3 days for L3 tech support to telnet into my Duo - which they never did (it's been offline for over a week trying to work through tech support). Anyway, I just used a SATA-USB hard drive enclosure that I had laying around to house my Drive1 disk. Currently transferring files from that drive to another external USB drive. I will update as to how things go and whether I ran into issues wth files > 4 GB. BTW, the VM does have the VMWare tools installed, so not sure if that is an issue and have not tested it with Player - I have the full version of Workstation.
Update - all files recovered just fine, except the larger ones. It seems that anything over 4Gb would truncate after 1.5Gb copied.
Update 2 - just realized I was copying on to a FAT32 USB disk...let me create a shared folder of the NTFS drive on the host machine.
Update 3 - how sad...didnt make a dfference. Still truncated to 1.5Gb.
Update 4 - tested copying the zipfile to create the VM on my laptop and open the drive = successful. That being said; image is as is - at best I am mediocre with Linux, so don't turn to me for support :). Created a temp ftp site - [removed]. posted single and multipart zip files of VM. Btw, this is on my home Internet connection, so dont look for blazing speeds. I will leave it up for a week or so. VM login info: root/rootadmin, vmuser/vmuser1 - pingleAspirantHi, acmtn.
Just tried to access your ftp as guest for the single part zip file - can't connect - must have left it too late.
Is it possible to reinstate the link for the short term ?
(unless someone else has stored the VM elsewhere :) )
Regards, Peter - acmtnAspirantok. re-opened.
- giobAspirantacmtn,
I just started downloading your image from your ftp, but only at 1 kB/sec!
Or could you upload it somewhere else?
Thanks - giobAspirant_vito,
could you post instructions on how to use and compile ext2fuse 0.5 in Linux?
I have the same "fuse-ext2: Can't read an inode bitmap while reading inode bitmap" error.
Thank you
(If you are italian we could exchange private mails)
