WD MyBook Duo Live Hilfe(GERMAN) by LehmiLehmi, 01 Mar 2015 19:32

OK I tried to install following the instructions on the Git site and it did not work for me. So I tried again and still no luck. All I got was a clean install of version wdhxnc-01.02.14.
So is there a firmware version issue, my MBWE is also using version 01.02.14 and will only reinstall its previous stored 01.02.14.img it keeps.
So do I have to change the version number from wdhxnc-01.02.14.img to wdhxnc-01.02.15.img for it to work?
Or is there a way to install via a script, wget or ipkg?
Any help would be great.

I want to use the NAS/USB copier Extra.
I hope you can also make a Extra for ipkg-web.

Now I'm looking at the MBWE II Blue Rings with the 60W powersupply I got for it (original was lost, former owner gave me one with too small capacity). As the disks spin up, there is a need for more than 30W for a few seconds. Then as the drives (new WD Reds, 2TB each) spin, while copying files, etc. its a steady 16W. When the drives are spun-down, but the machine is still on it is 11W. I'm thinking I'm going to be leaving the NAS just on all the time, with harddrives never spinning down (supposedly this is best for them), and that means:
16Watts * 24 hours * 365 days = 140kWh of electricity each year, or with electric rates here in Slovakia, approximately 14€ ($16). Since the machine still draws 11W when it is spun down, the negligible power savings vs. wear on disks is irrelevant to me. Also it will be in some side room, so the noise from the drives won't bother me.

With the MBWEII powered off but connected, I get 9W, and then with it disconnected from the P/S, the P/S alone draws 4W.

So when on with idle drives, it uses really 7W of power, and with active WD Reds, 12W of power. Unfortunately, the efficiency of a switch mode power supply is based on its full load current draw, and they can be very inneficient if used under rated. But the hard drives need the extra capacity when starting up, so what can you do?


I managed to setup the time machine of MacBook Air (Yosemite 10.10.2) to backup onto my MBWE 2.
It works well but I don't really understand how MacBook decides which shared folder to use and where finally it stores all files backed up.

Maybe the time machine uses not SMB but a specific network protocol?

Any hints about that would be much appreciated

Hey guys,

Registered so I could download the rescue files. I used this procedure yesterday to basically blow away a 1TB My Book to factory defaults, cause WD don't give you any proper way of doing that :(. And it worked well! Except for a few glitches below I thought I'd share :)

I had on hand Knoppix 6.0.1 on CD, so thought I would be good to go.
Placed drive into my computer as only drive attached.

Step 2: Using 'unrar x mybook_we_rescue.part01.rar' always gave me Failed. Tried different locations, nothing. Tried downloading fresh copies, nothing. Tried the GUI frontend, nothing. I downloaded the latest release of Knoppix, 7.4.2 (as of now) hoping that would fix it, and nothing. So I looked it up and found the built-in version of unrar is something like 0.0.1, and online i found v5, so I installed that, and was then able to extract the contents successfully.
Oh and if you're going to do this, and found it via, their step to run 'install -v -m755 unrar /usr/bin' produced an error for me. Running it as 'install -v unrar /usr/bin' works instead. Not sure what -m does, wasn't in —help.

Step 2(b): Worked like a charm. Once the drive was back online, I could use the same IP address given by DHCP :D

Step 6: If you don't use Linux/Unix much, there's one gotcha with using cfdisk; after setting the partition type to FD, choose the option at the end called Write, otherwise the new partition isn't saved :P

Step 10: Maybe a bit more description around replacing md4. For you readers, this means replacing the text /dev/md4 with text /dev/sda4 from within nano :)

Last Step: "I am happy its running again" :)

Thanks again!

I updated the ~/ files with the ddns address and ran the ssh keypair both ways and all is good again. great tutorial btw.

I did a ifconfig -a on the device and it doesn't show look right.
it has lo Link encap:Local Loopback
I don't see an inet ip address on this line nor the lines underneath it. Ex. 127.x.x.x

can someone else confirm this issue or come up with fix?

local loopback not running? by dz2kdz2k, 22 Feb 2015 19:26

I think thw mbwe II (white light) dual bay has a 200mhz cpu. how to determine cpu usage in percentage used currently? Ex. 30% of 100 when I run a command to test it.

Cool idea. As I'm upgrading the hard drives in mine, I might add one too. Though I'll look first, if it is possible to reprogram the shutdown script, so that the lights turn off last.

I wouldn't worry much about residual power with switch-mode-power-supplies— it is a fraction of watt, that is, on the kill-a-watt type meter I have, nothing registers. An old transformer based wall-wart on the other hand uses a lot— I had one for an ethernet switch, which when the switch was connected (12V, 1A specs, 12W DC needed), the transformer consumed 30W. When it was disconnected, it was pulling 13W.

thanks for the instructions but I couldn't get it working on new dev version: ;i even tried the instructions in the tar.gz. Both times, i started the tvmobili daemon and the command went through but i couldn't get to the web gui. i will contact the developer again as I'm clueless, otherwise we are out of luck on this wonderful dlna app.

I have another issue with this. the mybookworld has a ddns address from the etrayz nas, I did a ssh moc.b.a|toor#moc.b.a|toor to wd nas and it denied me altogether saying "The RSA host key for has changed,
and the key for the corresponding IP address ##.###.##.## is unknown. This could either mean that DNS SPOOFING is happening or the IP address for the host
and its host key have changed at the same time." I was able to make it autologin from the same network with say ssh 01.0.861.291|toor#01.0.861.291|toor and it pasted another key in known_hosts with the current IP. It has definitely changed several times on the WD nas since I set the keys up. is there a way to automate the first case no matter what?

It is extremely easy to bork a first-generation My Book World NAS device because it is difficult to know when the device has actually shut itself off.

IMHO, there is one very glaring defect in the design of the original (blue-rings) My Book World NAS device: There is no way to know if the device has well and truly shut itself off. I do not know if this issue affects other versions or not, but I would not be surprised if it does.

This is a problem because the blue "activity lights" are extinguished very early in the power-off sequence, while considerable disk activity remains to be done. Unfortunately, since there is no other way to know if the device has been completely powered down, it is very easy to assume that - since all the lights are off - that shutdown is complete.

This problem is magnified by the fact that we are constantly being reminded to disconnect power from devices that have been turned off to eliminate residual power waste.

If power is removed from the device prior to shutdown being complete, the result can be a badly borked device, or worse. Since there is no indication of activity except the blue rings, it is easy to conclude that the device is not active and then remove power too early.

Add a "pilot light", (power light), connected to the +12 supply going to the hard drives.

What I did was to take a small red LED in series with a resistor of a few K-ohms, and connect it between the hard drive's +12 line and ground.

I drilled a small hole in the bottom center of the front panel, installed the LED and resistor, and hard-wired it to the +12 and ground terminals on the main PCB of the device.

What this does is indicate if power is being applied to the hard drives, (i.e. Are the drives still spinning?), or not. Once the LED goes off, you can be confident that it is safe to remove power without borking the box.

What say ye?

(Note: Since the box is currently on my rack, running, I am not able to provide pictures or a more detailed explanation.)

Also the site has some sort of rescue tool for windows, but you have to "donate" 10€ via paypal to get access to it…

(I'm not able to paste full link, but that should be after this site's name)

Do you still need those? I am right now following this also:
but I am putting in two WD Red 2GB drives.

I have the original drives, which have the upgraded 02.00.18 firmware, SSH enabled, and optware/ipkg installed. So I can't make original images, but maybe these would help you?
When I get done with the drive upgrade, I could make those images.
Please PM me if these are still needed.

I have MBWE2 blue lights (e.g. RAID1) with two 500GB drives. PM me if you need the images for that.

Re: Files by Andrew RayAndrew Ray, 19 Feb 2015 20:39

So, got it working by following multiple pieces from this site.
Now my only problem is the usb : when I connect any stick / hdd, I can see it mounted in /shares/external/device-name/Partition-1/etc but I cannot see it in windows on network shared resources ( \\MYBOOKWORLD ).

Forgot to mention: Firmware: 01.01.18
And I see the hdd in Shared Storage Manager ( http ://MBE-IP/ ) on right under "System Summary".
Stick does not show up in web interface. Even after format in fat32.

Any idea how to proceed from here?


you could find an answer by following this link:
topic: installation-of-java-on-the-nas-under-fun_plug

Howto install java on a NAS Device (a D-Link DNS-345) what i personally see as a highlight as i can now use software that was not available to me before. Oracle provides a “Java SE Embedded”, which is suitable for NAS devices thanks to its reduced memory footprint. For the following tutorial you need to have fun_plug installed!

Go to the Oracle Page and choose “ARMv5 Linux – Headless”. Now you will be redirected to a survey, where you have to enter Name, Prename, Mail, Organization and Role. Then you will receive the download-Link via E-Mail. Click on this Link and accept the license agreement.
Java SE Embedded
Copy the downloaded file (in my case its name was ejre-7u6-fcs-b24-linux-arm-sflt-headless-10_aug_2012.tar.gz, but that is subject to change) to the NAS. I’ve copied it to /mnt/HD/HD_a2/, please adapt the following commands if you copy it elsewhere.

First create a directory:

mkdir -p /ffp/opt/java

Then unpack the archive from before:

cd /ffp/opt/java
tar xvzf /mnt/HD/HD_a2/ejre-7u6-fcs-b24-linux-arm-sflt-headless-10_aug_2012.tar.gz

Now create a link to the unpacked directory (“ejre1.7.0_06″):

ln -s ejre1.7.0_06 jre

Now put it permanently into the environment variables:

echo "export PATH=/ffp/opt/java/jre/bin:\$PATH" » /ffp/etc/profile.d/
chmod a+x /ffp/etc/profile.d/

Logout and Login into the NAS.

Check if it works:

java -version

This should display something like this:

java version "1.7.0_06"
Java(TM) SE Embedded Runtime Environment (build 1.7.0_06-b24, headless)
Java HotSpot(TM) Embedded Client VM (build 23.2-b09, mixed mode)

I used it: Java is now implemented on my MBWE and run correctly. (take care to upload the well adapted version of the Java package based on your processor!)
