I’ve missed some steps, now it works well, so the swap.c is the most important thing…
think you. :smileyvery-happy:
I’m glad it worked for you 
I was basically flying blind trying to put that guide together as I don’t own a MBL DUO but the community pulled together and we got it done
Hi,
Great guide. I’ve managed to back up my photos to another device and unbricked my MyBook live - Thanks!
I’m not out of the woods yet though, there is something wrong with the partitions on the disk. In DiskInternals its says there is 2.7GB unallocated. I also installed gdisk following one of your other guides, it tells me this…
MyBookLive:/DataVolume# gdisk /dev/sda
GPT fdisk (gdisk) version 0.8.5
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: present
Found valid GPT with protective MBR; using GPT.
Warning! Secondary partition table overlaps the last partition by
1202 blocks!
You will need to delete this partition or resize it in another utility.
The partitions look like this:
Number Start (sector) End (sector) Size Code Name
1 1032192 5031935 1.9 GiB FD00 primary
2 5031936 9031679 1.9 GiB FD00 primary
3 30720 1032191 489.0 MiB 0700 primary
4 9031680 5860532223 2.7 TiB 0700 primary
I still have a lot of media on it so would rather not wipe it if I can avoid it
Any help would be very much appreciated
Thanks

Hello,
I really hope that this topic is still alive and would be grateful for some help. I’ve spent 3 days trying to debrick my MBL using different boot CDs and virtual machines with no luck. At this point, I have no ideas left and would really appreciate your help.
Unfortunately, boot CD provided here gave me “Kernel panic” on 3 different PCs so I had to try GRML boot CD ( http://grml.org/)..) I tried to use Guide 2, so I deleted all the partitions from my MBL in Windows Disk Management. Then I booted the PC using GRML live CD and the first attempt gave me many errors, here is the complete output (some strange things are highlighted with red):
After that, I rebooted and tried again. This time everything was better however, some errors were still there. For example, I again saw the message: “./debrick.sh: line 280: gc: command not found”, mdadm –S /mnt/md0 again gave me an error. Anyway this time mdadm worked better but I saw some messages that I did not see in normal script output from other users (highlighted with yellow on the screenshots below) – maybe they are there since I ran the script the second time after the failed first attempt. At the end, I again got messages about swap (highlighted with green) and that’s it. The problem is that when I connect my MBL the led is still yellow. Below is the complete script output of my second attempt.
Here is how the drive is recognized in Windows after running the script:
I’ve tried it many times on 2 different PCs (1-st is a laptop with SATA-USB interface, the 2d one is a PC and MBL was connected via SATA interface directly). The result is always the same and I always have to do 2 attempts.
As I mentioned, I’ve also tried to run the script on a VM running Ubuntu 12. I didn’t get the error message about line 280 in this case but mdadm gave me message like this:
destroying was done, would you like to continue with installation? [y] y

I’ve also tried finnix boot CD but it gave me even more errors.
Please help, your assistance is much appreciated! And please accept my apologies for my English.

Vladimir Lyapunov
Please, disregard my post above. After trying 2 more Linux Live CDs Knoppix worked perferctly. Now sure what was wrong with others but now everything works fine. Great thanks for the guide!

I finally had time to come back to this. I think it might be drive failure, BUT I am thinking it might be with the electronics (the drive’s controller) rather than a platter issue.
I finally found a utility that can read the disk: UFS Explorer. After a few minutes, it recognized the drive, showed the two remaining partitions (including the ext4 data partition), along with the two partitions marked as “raw”. (Refer back to our conversation starting on pg. 41 in this thread: http://community.wd.com/t5/My-Book-Live/GUIDE-How-to-unbrick-a-totally-dead-MBL/td-p/435724/page/41 .)
I browsed some of my data partition and it appears all of the files are there! This software gives me an option to copy the files elsewhere, and I have started on it. Thing is, the process is taking f-o-r-e-v-e-r . It has taken 11 hours to copy 1.4 GB of data. As for the partitions, it recognizes my data partition and one of the RAID partitions as “ext2/3/4”, while the other two are flagged as being raw partitions. This is exactly what gparted told me when it was still working.
Prior to starting the copy operation, I ran a couple of scans. First, it did show a SMART error, something about file reallocation being one of the error flags thrown. I did a small surface test (read-only), and the way it displays results, it shows square blocks of different colors based on access time of the blocks of data. Normally most of them will be green, but the drive is alternating between green and red blocks, the red being >0.500ms access time. There is a pattern to how the reading is alternating: I would get maybe four rows of green blocks, followed by six or seven rows of red blocks. It’s consistent. And while copying the files, the progress bar operates in the same manner. It will pause for a minute or three and do apparently nothing, then it will quickly copy another hunk of the file.
I figured two things might be happening. The drive’s controller is damaged (probably from the power outage), causing it to read so much, then “hang” in some sort of wait state. This is the most likely, since it has the same behavior when reading sequential blocks during the surface test, and when it is copying files.
Or, because of the corrupted partition information, the drive is taking a long time to seek out and retrieve the data. The partition table does appear to be corrupted since it is still missing the descriptors for one of the two RAID partitions and the swap partition.
I also wonder if the drive’s SMART error status might be preventing the drive from spooling up and copying the files. I cannot find it, but somewhere, there was a diagnostic utility that bypassed SMART (and IIRC the system BIOS) to work with the drive directly, but I was not able to find it again. I’m wondering that if the SMART parameters could be reset (the drive is probably a goner anyway), if the drive might free up again so I could at least copy the files off of it.
Not that I can’t recreate the data, but that is time consuming, and I want the challenge of fixing this drive or at least getting the data off of it.
mdadm -S /dev/md0
./debrick.sh rootfs.img /dev/sdaCan I know why should type "mdadm -S /dev/md0" before running the script?Is it OK to skip "mdadm" for MBL 2T?
Is there an similar guide for My book Cloud ?
NFODIZ
Thank you, from yet another satisfied customer.
Having lost access to Dashboard, ssh and all non-public shares I began to think I’d lost access to it all. As this was my backup, I hadn’t kept another backup! Nevertheless, I wanted to keep it, so went with your version 1 guide, and after an unsuccessful first attempt (something to do with raid) , was able to restore full access to my MBL data, Dashboard and ssh on second attempt.
My only real hiccup, was in using a 16Gb Thumb drive, as this was formatted to ntfs, and although recognised as /dev/sdd1 in gparted, wouldn’t mount, as file system wasn’t recognised !!!
I then used a 4Gb Thumb formatted as FAT. and success.
All my share partions were there, but at risk of losing data, I moved them all under the Public share, so that if it happens again (was my fault for trying to install mysql-server), I will still have access.
Hi, I have a non accessible drive. Blue flashing light with alternate green light flashing.
I have taken it out of the casing and accessed it via the linux reader and seen the drive partitions. I want to get all my images and music from the drive so have copied the data from the raid partition with the most data on but only seem to get a whole load of folders without the actual data im after. After doing a search in the retrieved data there doesnt seem to be anything there apart from the mass of folders.
My question is which part do i need to copy to retrieve my data before attempting to debrick it and get it working again?
if its a soft raid will I need to access it as a raid to get the fragmented data off?
thanks
Jim
I’m a new client for WD community forum.
I’ve been trying for a couple of days to debrick my wd my book live 2T.
I used both scripts supplied in this feed… but always had an error when copying image to disk.
I’ve used virtual machines … I’ve used my raspberry pi… and now i’m using my system rescue boot… but always with the same outcome…

Hi Daremo, hope you are still active here…
Having problems with r-linux … When scanning my MBL it has a few errors early on - I/O errors at the moment.
Do you scan “showing files” first?
I’m at a loss as i’ve never been this deep into it before. I have pictures i need to get off of the kids 
Any guidance greatly appreciated.
Hi,
I’m trying to unbrick my MBL using the guide.
I get errors that I’m hoping someone can help me work through.
First, Gparted complains that…
"The backup GPT table is not at the end of the disk, as it should be. This might mean that another operating system believes the disk is smaller. Fix, by moving the backup to the end (and removing the old backup)?
Not all of the space available to /dev/sdc appears to be used, you can fix the GPT to use all of the space (an extra 4294967296 blocks) or continue with the current setting?
Unable to satisfy all constraints on the partition.
I tell gparted not to fix anything and I proceed with running the script.
At the end, the script shows a bunch of error messages:
"mdadm: cannot find /dev/sdc2: No such file or directory
synchronize raid… done
copying image to disk…
dd: writing to ‘/dev/md0’: Input/output error

umount: /mnt/md0: not mounted
mdadm: stopped /dev/md0

My device still appears to be bricked though.
Anything I should do differently?
Thanks!

I have a dead-ish MBL - it goes to green light but can’t be seen on the network and the 1TB hard drive seems to have a corrupted partition table.
I’m currently running a scan using R-Linux and it’s picking up partitions, files etc. which is encouraging, but does this software actually rebuild the partition table and write it to the disk so the disk can then be used in its original state, or does it just recover data?
If it doesn’t automatically repair the partition table, is there another way to do this reliably?
tried at least twenty times fat32, fat, ntfs usb drive and sd card yet i always get the unable to mount after i enter
mount -t vfat /dev/sdb1 /mnt/usb
and the sdb1 does correspond to the proper drive with all the proper files intact on it.
i was totally able to get all the files off of it as it was still visible with the programs sugessted in the howto,
cannot seem to get anything started though as i can’t mount it.
any ideas anyone?
I follow instructions by typing the following commands because I have change my hard drive with a new one.
mkdir /mnt/usb
mount -t vfat /dev/sdb1 /mnt/usb
cd /mnt/usb
mdadm -S /dev/md0
./debrick.sh rootfs.img /dev/sda destroy

Deat all,
the disk of my MBL is dead, ou can hear horrible sounds form it…
I don’t a PC with SATA adapter, only a laptop and a SATA-to-USB adapter.
Can I use it to flash the software on a new disk and then install it in the enclosure?
Thanks,
Max
