Complete Fresh Backup of MyBook World 500GB - Firmware: 01.01.18

What is this
These are backups of a brand new, never booted, Western Digital MyBook World Edition 500GB (single drive not II) Since the only way people as of creating these have to restore a bricked MB WE is to rebuild a Debian edition using the sources available which takes a long time and is confusing to many. I decided to open up an brand new one and rip the hard disk images, partition table, master boot record, and complete file systems keeping all permissions. The Firmware is 01.01.18. I used System Rescue CD, to obtain access to the drives. Running PartImage fails, so I used DD.

Disclaimer
I have not tested that these work to restore a bricked system or if they will work on other sizes or the two disk version. So in essence, you screw it up by using any part of this… it's your fault, I take no blame. I would suggest you have Linux knowledge prior to using or attempting to use these. Of course, if you took the risk of hacking your MyBook World, then you should have already known this. I guestimate that these should be able to recreate a fresh out of the box MyBook World Edition. I am not your tech support, so don't try to contact me for it. Post to the forum, and if I can I will try to help.

Files
- Master Boot Record -

• SDA_MBR

This was acquired by running "dd if=/dev/sda of=sda_mbr bs=512 count=1"
You would restore this by "dd if=sda_mbr of=/dev/sda bs=512 count=1"

- Partition Table -

• SDA_PTAB

This was acquired by running "sfdisk -d /dev/sda > sda_ptable"
You would restore this by "sfdisk /dev/sda < sda_ptable"

- BitByBit Disk Copies -
(These are exact copies of the partitions and will extract to be the partition size)

• SDA1_IMA.BZ2
• SDA2_IMA.BZ2
• SDA3_IMA.BZ2
• SDA4_IMA.BZ2

These were acquired by running "dd if=/dev/sda1 | bzip2 > sda1_image.bz2" on each partition where sda1 is sda1-sda4
You would restore this by "dd if=sda1_ima of=/dev/sda1", however since I piped them out as bzip2 files you will need to pipe in the std out of bzip into dd. I can't remember the command line options at this time.
WARNING: SDA4_IMA.BZ2 will extract to 461.89 GiB, as each file will extract to its original partition size.

- File System Dump Containing Permissions -
(These contain the file system for each partition while keeping full fs permissions)

• SDA1FILE.TAR.gz
• SDA3FILE.TAR.gz
• SDA4FILE.TAR.gz

This is acquired by mounting each partition as read-only as ext3 and tar/gzipping them with permissions. I can't quite remember which command options I did at the time.
You would restore these by mounting the partition and just extracting and writing over your files in your partition as root. You may need to delete other files you have created that are not in the archive, especially in your init.d.
You can also grab the files you may have corrupted individually as this is a copy of the files and structure. When mounting the FS you need to specify the type as ext3. Auto will detect the raid configuration and is unable to mount.

---

File Downloads
The files are packaged as 7Zip Archives, use 7-Zip or WinRar

Since I am not positive about storing these files and Western Digital's EULA, I posted them on rapidshare.

Please mirror and post here. Posting back to rapidshare is pointless unless you reencode them in another compression format, as once a file is deleted, so is it's hash.

This first link is probably the one everyone will probably use. It contains the file structures (with the files) with the mbr and partition table.

• SDA1FILE.TAR.gz
• SDA3FILE.TAR.gz
• SDA4FILE.TAR.gz
• SDA_MBR
• SDA_PTAB
• ReadMe.pdf
• ReadMe.txt

WD_MYBOOK_WE_500GB_FILE.7z (59MiB)

---

This link will probably not be used by many. It contains the raw disk images with the mbr and partition table.

• SDA1_IMA.BZ2
• SDA2_IMA.BZ2
• SDA3_IMA.BZ2
• SDA4_IMA.BZ2
• SDA_MBR
• SDA_PTAB
• ReadMe.pdf
• ReadMe.txt

WARNING: These expand to the 500GB, mostly of empty space.

Before I demolish the my book world edition: how do I open it?

Re: Complete Fresh Backup of MyBook World 500GB

ionoff 1192291418|%e %b %Y, %H:%M %Z|agohover

There are two nobs in the air holes, you press down on and pull the side casing off.

I have pictures I am going to put together in a tutorial.

Re: Complete Fresh Backup of MyBook World 500GB

floris 1192385236|%e %b %Y, %H:%M %Z|agohover

It was a bit tricky but found it out by use of these nobs and two screwdrivers. Pitty I teared the rubber band somewhat first when I removed it.

btw: there is a flaw in the tutorial. In the commandline for creating the SDA_MBR: hda => sda.

Re: Complete Fresh Backup of MyBook World 500GB

ionoff 1192401699|%e %b %Y, %H:%M %Z|agohover

good catch,
Can you get the md5 of your SDA_MBR

The one in the archive is:
2915da05007150c56eac34d93f110429 SDA_MBR

md5sum sda_mbr

No match. I retrieved and verified this mbr twice, without any other disks attached to the system used. But the mbr from the archive can still be from a my book.

Re: Complete Fresh Backup of MyBook World 500GB

ionoff 1192474233|%e %b %Y, %H:%M %Z|agohover

yeah, when I have time I will crack open the mybook I got the dump off of (its not clean anymore, as I have been using it as a compile box, just because x-compiling for arm tends to have problems) and compare it.

Until then, could you post your MBR and add a link to it in the wiki entry?

Re: Complete Fresh Backup of MyBook World 500GB

lukasz 1193324829|%e %b %Y, %H:%M %Z|agohover

Can somebody post the link to the newly dumped sda_mbr from mybookworld 500GB? the one posted is not good.

Re: Complete Fresh Backup of MyBook World 500GB

To drop the disk image files onto the partitions I used this command:

bzcat <file> | dd of=<dev> & pid=$!;while (true); do { clear; kill -USR1 $pid; sleep1; }; done

This will decompress and dd the image giving status output.

And? You have the drive booting? My friend tried to use files posted here but in his opinion MBR is wrong - system does not want to boot, no blue fun lights….

Re: Complete Fresh Backup of MyBook World 500GB

ionoff 1193327823|%e %b %Y, %H:%M %Z|agohover

I can confirm that I did copy the MBR from the wrong drive in my archive.

http://mybookworld.wikidot.com/forum/t-23918/recovering-original-fw-tested
Has a few files from the original archive + a large chunk of the front of the disk with a working mbr in it.

I am waiting for some free time to rewrite the instructions and include new files.
I will essentially wipe a world edition clean and rebuild from scratch with using the file only method instead of the disk images. (except the mbr and ptables)

I am planning on writing a bash script to rebuild it for you. (By using the file method, it should not be size dependent and should be quicker at restoring.)

Also the MBR in the other post, is a 100mb disk image (mostly empty space), it does not need to be this big.
The MBR bootsector is under 512 bytes. (really just a pointer to /boot or the bootloader wherever it is)

I will still need someone to test it on a bricked WE II (2 drives) to see how the raid is, or if someone has a new 2 drive system and is not afraid to open it, mount and rip the filesystems and mbr and ptables)
WARNING: only try to restore on a WB II if it is the last resource. I do not have one to test with and I don't want you making it worse with these files.

I used the installer from http://www.ismprofessional.net/pascucci/index.php/mybook-repository/ to modify the MBR that you provided and have the blue lights working but i'm not seeing it on the network (i'm working on it now). I created a simple script if you want it, it uses the disk images so it will take some time to finish.

-Cut Here——
#!/bin/bash
#Restores a hard drive to the original My Book World file system
HD=$1
if[ -z "$HD" ]; then
echo "./restore.sh <device>"
exit
fi
echo "Restoring the MBR"
dd if=SDA_MBR of=$HD bs=512 count=1
echo "Restoring the partition table"
sfdisk $HD < SDA_PTAB

echo "Restoring partition 1"
bzcat SDA1_IMA.BZ2 | dd of="$HD"1 & pid=$!
while (true); do { kill -USR1 $pid; sleep 1; }; done
echo "Restoring partition 2"
bzcat SDA2_IMA.BZ2 | dd of="$HD"2 & pid=$!
while (true); do { kill -USR1 $pid; sleep 1; }; done
echo "Restoring partition 4"
bzcat SDA4_IMA.BZ2 | dd of="$HD"4 & pid=$!
while (true); do { kill -USR1 $pid; sleep 1; }; done

#Temp fix
dd if=$HD of=mbr bs=512 count=1
./installer mbr
dd if=mbr of=$HD bs=512 count=1
-End cut-

I'm about to turn it off and see if there are any log messages, i'll let you know.

MBR from an out of the box WD MyBook WE 500GB is added as file to the page.

I feel like a wiki newbie. Note for myself: wikidot likes to hide files added to pages. I should not forget to post a link to the file on the page. The file is otherwise only visible when hitting the file link at the bottom of the page.

Right. Done so for the sda_mbr file. The link to that file is now also on the page. Enjoy.

kknapp 1193360297|%e %b %Y, %H:%M %Z|agohover

Now that I've seen the new sda_mbr it can be duplicated on any drive with the program "installer" from either the WD source or the one at http://www.ismprofessional.net/pascucci/index.php/mybook-repository/

First erase the MBR
dd if=/dev/zero of=/dev/sda bs=512 count=1
Now create the partition talbes
sfdisk /dev/sda < SDA_PTAB
Use "installer" to modify MBR for bootloader
dd if=/dev/sda of=new_mbr bs=512 count=1
./installer new_mbr
dd if=new_mbr of=/dev/sda bs=512 count=1

Even with the new MBR the device will not function without the sectors between the MBR and the start of partition 1. This is were the stage1.bin and u-boot.img bootloader reside. I rebuilt the buildroot and stage1.bin and u-boot.img from the WD source and I can get the LED's on the front to light up. It doesn't dhcp or respond to the default IP "192.168.1.128" list in "/etc/default-setting". And none of the files on the drive seem to be touched. I don't have the serial cable (on the way) so I cann't see what is still failing. I think it has to do with u-boot. That were I've gotten so far

Hi I have same problem. I did these:
1)Copy rescue.img to /dev/sda
2)Copy (dd) sda1-3 to /dev/sda1-3
3)in etc/fstab on sda1 changed mdx to sdax

Booting is ok, lights will come up. But no response on LAN. Tried connecting to router/pc/dhcp/noDhcp, doesnt matter. 192.168.1.128 or mybookworld isnt accessible.

Somebody knows, what am I doing wrong?

Re: Complete Fresh Backup of MyBook World 500GB

According to my linux compatible friend who is helping me with the WD Mybookworld 500 to be able to really solve the problem we need more than just MBR - exact copy of the first 1 MB or a bit more maybe- 3MB of the HD is needed, and the partition table description (if it is different than the one on the top of the page) - we have tested new MBR + all partitions from 2 files and is does not want to boot. According to my friend nice new MBR what we have now is pointing to some sector and head on the drive which is beyond the MBR but before partition, so that is why exact copy is needed, with the description how it was copied to allow to copy it back.

Re: Complete Fresh Backup of MyBook World 500GB

lukasz 1193397670|%e %b %Y, %H:%M %Z|agohover

My linux friend found on the on the net first 25 MB of the drvie - so we have what is between MBR and the partion. But this in not the end of the problem - drive is booting now, but we still do not have communication on LAN - he is working on it but the real remedium would by the bit by bit copy of the first 3 or maybe 5 GB of the drive, with all partitions and data except the "data" partition.

Re: Complete Fresh Backup of MyBook World 500GB

kknapp 1193408304|%e %b %Y, %H:%M %Z|agohover

If you extract the files for sda1 and look in 'usr/www/nbin/dm_formatInternal.sh' line 70 is "dd if=$OLD of=$DEV bs=512 count=48194" which copies the first 16MB from the original drive to a new drive. I believe this is what is needed to get these images to work.

On http://mybookworld.wikidot.com/forum/t-23918/recovering-original-fw-tested in the comments there is a new rapidshare link to a working rescue.zip. The rescue.img it contains is only 3MB. I just finished testing with it and I get the LED's to light up but no activity on the NIC.

Re: Complete Fresh Backup of MyBook World 500GB

lukasz 1193415048|%e %b %Y, %H:%M %Z|agohover

Friend of mine managed to get it working!. using the beginning from rescue.zip and the rest from the files 2 files listed here. At this stage it started to boot but still no activity on the LAN. - By putting some logs into the booting procedrure (do not ask me at this moment where) he ended up with the discovery that the in etc/fstab dev mda1 should be dev sda1 and the same for the other partitions - after that procedure disk is visible on lan. The only thing which is not working is the WD remote access software - for some reason it can not be activated by the web interface. Rest seems to be ok.

Anyway if somebody could make a exact bit by bit copy of the first 3 GB (gigabytes) which will contain all small partitions and post it somewhere it would be probably the best solution…

I have a 1TB World Book Edition that is brand new. It has a single drive inside.

If you can give me the correct commands to create the first 3GB, I will try to create an image. I have several World Book shells and want to put 500GB drives inside and make them work like the 1TB version.

read my post at http://mybookworld.wikidot.com/backup-images-of-mybook

what you need is the mbr, ptable and disk images (really file is all you truely need)
We have had lots of success restoring we's the past few weeks.

3gb = 3221225472bytes
/512bytes = 6291456

dd if=sda_diskimage of=/dev/sda bs=512 count=6291456

however I prefer to pipe it to bzip2 to compress the image

dd if=sda_diskimage of=/dev/sda bs=512 count=6291456 | bzip2 > sda_image.bz2

but you will probably want to get each partition individually or just use the base ones I submitted from a clean system, with the mbr located at the bottom.

After what should be a really successfull bringing to life using files from this page I have following problems:

- When IP is set up as static everytime I want to access the device by web interface it produces cache errors, each page must be reloaded
- There are some kind of problems with Mionet - when it is turned on device can not be accessed through the web interface (but shared directories are visible on lan)
- web interface produces message 500 Internal Server Error frequently
- password can not be modified - even if it is changed, after cold restart it returns to standard 123456

Anyone has a clue what can it be? If somebody knows where to get the really "clean" image of all small partitions? to get rid of this problems?
