How To Recover Data From WD My Book World Edition NAS Device

netvizier 1221882860|%e %b %Y, %H:%M %Z|agohover

I have a single-drive 1TB Western Digital (WD) World Edition NAS device. Recently, something happenned to the device and it stopped working, but not before I had moved significant amounts of important data to the drive. I opened the device and connected the hard drive directly to my computer via a USB-SATA adapter. This is a step by step guide explaining how to recover data from the drive, just as I did:

1) Unfortunately, Windows XP is unable to see the drive because it is not in a format recognized by the operating system. So, instead burn yourself a Live CD of Ubuntu and boot to it.

2) Launch a terminal session and issue the following commands:

$ sudo modprobe md
$ sudo mknod /dev/md4 b 9 4
$ sudo apt-get install mdadm
$ sudo mdadm --assemble /dev/md4 /dev/sdb4
$ sudo mkdir /media/xyz
$ sudo mount /dev/md4 /media/xyz
$ sudo chmod -R 777 /media/xyz

3) Now you should be able to see your data by browsing to /media/xyz.

This is what worked for me. Please note that the process is slightly different for the two-drive models.

Good luck!

PS: For what it's worth, I now use a Buffalo Linkstation Pro Duo 2TB NAS device with RAID mirroring.

This Bufallo looks good on paper, but is in a totally different price-range. How does it perform in the real world? They bought something like that at work from Intel which even had RAID 5, but heard it didn't perform to expectations….

And the most important question of all…… Can it be hacked?

Performance on the Buffalo NAS is great — much much faster than anything I was ever able to get out of the WD NAS. I highly recommend it, because in the end you get what you pay for, and if you have valuable data, you will probably need to spend $200 - $500 on a good redundant NAS solution depending upon how much disk space you need. To respond specifically to your statement: it is performing beyond my expectations.

With regard to whether it can be hacked: I'd wager yes, probably so. But, in all fairness, I would ask why? What is it that you want to do with it that it can't already do out of the box, and do well? You want a media server? It's got it. You want an FTP server? It's got it. The list goes on and on. Look into it — you might be pleasantly surprised.

Thanks,

nv

There are a million reasons why it needs to be hacked! ;)

Personally, I don't like having a NAS box that I don't have SSH access to. Web configuration is nice, but never has all of the options that I'd like to see… 99% of the people who will buy one just want a place to store files, the other 1% are people like me (and others on this site) who like to find out what "else" this box can do…

For example. My MBWE2 is used mostly for storing files. I can set that up in the web interface, but I personally have a couple of shares that are not visible, which is not an option in the web interface. Not only do I want the share to only be accessible by certain users (which is an option in the web interface), but I don't want it showing up on the list either when someone browses to the box (not an option without SSH access)…

Hacking the Buffalo box may be for something equally simple, or maybe it'd be determined that it would run a bittorrent client better than an MBWE2, or any number of other possibilities.

Just my $.02

Much faster is still not really fast….

What's the raw ftp-speed?
If it has a gigabit interface the maximum speed possible would be around 100 MB/s…..
A 30 MB/s would be nice….

I followed your directions to get the data from the faulty SATA drive in the MBWE drive I own. Got through most everything all right, but can't see any images in the xyz folder. Drive is now mirrored on My Computer as an external USB drive, but clicking gives failed mount error and the final two steps in your directions indicated a glitch :(

here's the readout —-

ubuntu@ubuntu:~$ sudo mount /dev/md4 /media/xyz
mount: you must specify the filesystem type

Have you got a fix for this?

Re: How To Recover Data From WD My Book World Edition NAS Device

alephsmith 1229676661|%e %b %Y, %H:%M %Z|agohover

From the mount man pages:

The standard form of the mount command, is
mount -t type device dir

Try using the option -t ext3 to tell Ubuntu what format the filesystem is in.

madwater 1229732231|%e %b %Y, %H:%M %Z|agohover

here's the response —-
ubuntu@ubuntu:~$ sudo mount option-t ext3
mount: mount point ext3 does not exist

please advise…

give the program language line by line, please. I'm not Ubuntu savy

Re: How To Recover Data From WD My Book World Edition NAS Device

alephsmith 1229732929|%e %b %Y, %H:%M %Z|agohover

$ sudo mkdir /media/xyz
$ sudo mount -t ext3 /dev/md4 /media/xyz

What this does:
1) Makes a directory called /media/xyz, this is where you will mount your drive to.
2) Mounts the ext3 filesystem on the device called /dev/md4 at the location /media/xyz
Once the drive is mounted you should be able to access the flesystem at /media/xyz. Ubuntu will usually automount the filesystem, but because it is marked as linux raid rather than ext3 it has a little trouble.

ubuntu@ubuntu:~$ sudo mkdir /media/xyz

ubuntu@ubuntu:~$ sudo mount -t ext3 /dev/md4 /media/xyz
mount: wrong fs type, bad option, bad superblock on /dev/md4,

(could this be the IDE device where you in fact use
ide-scsi so that sr0 or sda or so is needed?)
In some cases useful info is found in syslog - try

Checkout ebay auctions from user datamajic

This guy has a listing to check out your hard drive for 20.00 and if data is recoverable it only costs 500.00

The recovered folders /files are send back on a USB 2.0 external hard drive.

Hello Everyone, it seem like a long time nobody has posted anything here, but here I go, I need HELP!

I have a WD II , 2 500GB drives with Raid 0, so I have 1 TB of storage. Basically, I wiped a folder located inside /shares/internal.

I have not to say that folder is very, very important… and, after a lot of, do this, do that… I just want to ask simple steps to do this:

I have an Ubuntu linux machine, testdisk, r-linux and a lot of tools that claim to recover linux files, so, I want to connect the two SATA drives from my WD II 1TB , 2 disk edition into my Ubuntu machine and MOUNT the drives so I can see plain and simple the data, and then be able to recover with those tools.

Assume I have all that connected, Ubuntu up, drives there…

HOW DO I MOUNT THE TWO DRIVES ????

just that …that simple task I want to do, I believe me… maybe I am missing something but I can't make it happen.

Hope some one can help with that… THANk YOU in advance!

Cheers!

OK, let's check what disk you have attached:

fdisk -l

You may need to change the device locations in your command to make it work properly.
For example if you run this command: sudo mdadm -assemble /dev/md4 dev/sdb4 you need to make sure that /dev/sdb4 is the actual device you want to be using.

To be honest, I don't know what you are actually trying to do, why are you using RAID for a single drive? I've always just mounted it as a plain ext3 drive.

Nevermind on the above…just needed to update Ubuntu.

New problem though…

The command:

$ sudo mdadm —assemble /dev/md4 /dev/sdb4

Results in:

mdadm: cannot open device /dev/sdb4: No such file or directory
mdadm: /dev/sdb4 has no superblock - assembly aborted

This looks more like a MyBook problem.

Hi this is my first post.

After struggling for o few day with this recovery problem also.
got a work around by re creating the RAID with this command
$sudo passwd
this is to change the root password so you can su to change to root
$su
use your newly created root password

search in /dev is there a mount of sdb4

try running
#ls /dev | grep sd

if you can see it on the list
then continue with

#mdadm -Cv /dev/md4 -l1 -n2 -c64 /dev/sdb4 missing
asuming that you have WD Mybook world edition 1

then you can mount the md device using
#mount -t ext3 /dev/md4 </local_mountpoint>
#cd </local mountpoint>

hope this helps.

I am actually working with the WD Mybook World Edition II (w/the dual 500G drives). What effect does that have?

Re: How To Recover Data From WD My Book World Edition NAS Device

netguy 1233862161|%e %b %Y, %H:%M %Z|agohover

Hi,
Assuming you configure your MyBook II with RAID 1 mirror, it will create the metadevice mount point of /dev/md4 so you can manually mount it to your local system and read the partition and back it up by copying to another drive manually.

if you configure with RAID 0 than you would need to connect both drive and recreate the metadevice mount point by issuing a command
#mdadm -Cv /dev/md4 -l0 -n2 -c64 /dev/sdb4 /dev/sdc4

hope this helps

I'm not a Linux wizard, I've tried to follow the instructions but got weird error messages and as a last try I connected both A and B drives at the same time and without any magic the ubuntu file browser recognized the drives and I saw all my precious data on them!
It was a busy few days' time while I tried to find the solution and recover my data from the crappy MBWE - I regret the moment when I chose to buy this crap :(
Now I can have a run with the WD support to replace my drive but to be honest I would much more happy to see my money back instead!
