Hello everybody,

First, best wishes for this new year 2015 !

I built a tool MBWE-Extras in Github ("Downloads" repository) to help non IT to manage features on My Book World Edition I or II.
Mainly, adding options, like merging logins in only one, timeout session or features, like no-ip free site periodic validation, Twonky installation, Feature Pack Manager installation, exTplorer to explore folders, locally or remotly with only web access, and so on…

If it would help only one person, could satisfy me.

Best regards.
Patrick

Guys, help me out on this.

I purchased empty MyBook Live Dou ant bought 2x 2TB HDD for this.

When I turn on empty MyBook at first there is Blue light and after that Solid yellow light that keeps forever.

When I put both HDD inside, same thing happens.

Also when I try tu Reset it, nothing happens.

Is my NAS defective ? What light should be when there is no HDD inside and when the HDD is empty or defective ? I believe solid Red, not yellow.

Thanks for input.

One fine day my WD MBL stopped showing up on network, on further investigation found out that I could not ping it nor ssh it.
First I thought that the IP must have changed, after checking out the router configurations found it wasn't in the network.

I rebooted it lot of times, tried the reset option using a pin, but no luck.
The devices boots up with the blue LED and turns to yellow LED and never changes..

Any suggestions?

P.S: I had recently upgraded the twonky server 7, though I don't think this might be causing any boot issues, but just a FYI.

Hi,

I have a WD My Book 1TB NAS (model: WD10000H1NC-00). Can I replace its hard drive for a bigger one? Like 2TB or 4TB? Are there any limitations?

I've installed SickRage, and it can't auto update since my openssl version is too old (0.9.7).
How can I update to a newer version, preferably newer than version 1?
ipkg doesn't list anything newer than 0.9.7

Thanks

Hello,

I got this box from a friend, but only with one hdd, and that already formatted and full with other stuff.
I used the rescue-procedure from "hacks and tutorials" page, but I believe it is for the single drive as in web interface I see no info about Storage and beside "Safely Remove USB Drive", I have nothing on "Drive Management" page. Beside this I tried contactinc "teinturman", but no success, and also I believe it's tools are just for single drive, not double drive as mine.

Is there any tutorial with links to drive images that still works ?

Thanks in advanced.

Issue:
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.

Solution:
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?

Jim (JR)

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

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.

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?

Hello

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

Hallo,

Hoffe ich finde jemanden von euch hier der mir in Deutsch erklären kann wie ich auf meine Festplatten das Betriebssystem installieren kann, um sie für mein WD MyBook Duo Live Gehäuse lauffähig zubekommen.

Hello all. This is my first post on this forum so I'll try not to make it too painstaking :)

I currently have a 6TB MBLD. I am currently running low on space and figured it might be time for an upgrade. I was wondering if I can remove the two 3TB HDD's in there now and replace them with two 6TB HDD's? I know I both HDD's have to be the same model #, but I'm not sure if the enclosure will take higher capacity drives. The stock drives in there right now are two "WD30EZRX". I was thinking of purchasing two "WD60EZRX" HDD's, same model series just 6TB instead of 3TB.

I'd really love for someone with experience to chime in on this. Thanks in advance! :)

Hi , i have a my book live 3TB version, but the 3tb wd green drive was totally broken, with full of bad tracks
I want to replace it with a new wd red 4T drive, so here's the question, could it work with larger storge?
If anyone know this, please give me some advise
thx

Good day everyone,

Recently I had a power outage at my house which resulted in to this behaviour below. I would greatly appreciate it if anyone could give me directions on how to make it work again.
I have no idea what this 'signal 11' is and how to fix it. I've only been able to hook it up and run some test commands on the system and i'm glad that the drive is still fine.

Hello i am new in forum and i need help. I had installed transmission on my book live with many torrent on seeding. After a firmware update the old transmission install needs new installation but i loose all torrent history. Anyone know a way to restore my torrents list? Either for now or for future use what i have to backup so i can restore my settings after next firmware update. Thanks

All my blu rays are ripped using makemkv and stored on the WD My Book Live.

Most of the them play just fine on my TV (Panasonic) but some will not and the picture goes kinda blocky and corrupted looking. Sound is ok. The ones that fail tend to be newer ones, but it's no hard and fast rule.

If I run the same files (i.e. directly off the network drive) through a different media server (ps3mediaserver) all is fine.

So the problem appears to be Twonky. The same issue appears if I run the WD Twonky 5 version or if I upgrade it to Twonky 8, as described elsewhere on this forum (sorry I'm not karmarish enough to add links, but it's the "complete-guide-to-upgrade-to-twonky-7-version-my-book-live-o")

Anyone got any idea how I can have a working media server on the My Book Live?

Hi, I cannot use this rescue procedure because of 512Kb per sector (I think). I stuck at /dev/sda4 which is not 2,9TB (at the end) but only aprox 800GB. How can I tweak partition table of structure for 3TB drive? I have 3TB WD Red edition. Should I create all of these partition by my own, or use GPT table insead of msdos? If there is no way how to use the rest of drive for only one partition. can I use 5. partition as logical (because od msdos partition table) and add it to the sda1/etc/fstab (will it work?).

Or… Is there any way how to install ubuntu/debian into this drive?

Can I use parameter bs=4092 instead od of bs=512.. will it core of mybook linux/unix boot?

Can someone please help? I can donate you :-) My original enclosure is WD5000G032-001

In January, my firmware got upgraded and I lost all my FeaturesPack. I was also a registered member.

So, I re-installed the the feature pack, it wouldnt take my old registration code.

I wrote to moc.liamg|stiblevelhgih#moc.liamg|stiblevelhgih…no answer.

So I even donated again…thhis was almost two months ago….still no code??

Where do I go from here? I really miss OpenVPN.

Any help appreciated…Im guessing that I will need to hack it manually…

Hello All,

I just get back form warranty clame my WD My Book Live and what was supprise that on new one i have DLNA Server. Unfortunatlly many files are not supported on this server and my TV. On Twonky server was better and i want to ask if that is possible to install Twonky Server on MBL? Frirmware on MBL is 02.43.09-038

basically, i got the mybook world edition 2 a few months ago from my brother and it was working fine then.
had a good transfer speed of 10MB/s which im guessing is the limit of my 100Mbps network.

but recently it started going slower and slower…

right now the transfer speed is only 2-3MB/s which is to slow to work with in lightroom or to watch a movie at full HD…

to shed some light i logged into the device and did a hdparm …

 dacotacowd:~# hdparm -tT /dev/md2 /dev/md2: Timing cached reads: 242 MB in 2.00 seconds = 120.94 MB/sec Timing buffered disk reads: 7 MB in 3.31 seconds = 3.45 MB/sec dacotacowd:~# umount /mnt/data/ dacotacowd:~# hdparm -tT /dev/md2 /dev/md2: Timing cached reads: 270 MB in 2.00 seconds = 134.99 MB/sec Timing buffered disk reads: 22 MB in 3.31 seconds = 6.65 MB/sec 

wait, why is it so much faster when the raid is unmounted ?

can anyone shed some light here? :/ a fix?
