Debricking Script for My Book Live Duo
First, credit dan kvelstad and his post for the My Book Live's. I modified his script that was for the MBL to make it viable for the MBLD. Unfortunately I can't post the link since I'm a new user.
This will get your MBLD debricked, but I did have some issues with the Dashboard giving me some errors afterwards, but I was able to access it through SSH and get my data off. Then I just did a Factory Reset through the Dashboard and everything worked perfectly.
First, you will want to take out the A drive from your My Book Live Duo, this is the drive you will be running the script on. Attach it to your desktop in an empty SATA.
Next, download the My Book Live Duo firmware from the WD site. You'll want to get rootfs.img out of it; open the .zip, then open the .deb, open the data.tar.lzma, then open data.tar, then open the . folder, then open CacheVolume folder, then the upgrade folder and you'll find it in there.
Copy the script below and save it as debricker.sh.
I used a Ubuntu LiveCD on a USB stick for this, but you can just do a regular LiveCD. Put both the .sh and the .img file in the same location. You'll need to open a terminal and set the root password using "sudo passwd root", then change to root with "su root". Then you'll need to install mdadm and curl using "apt-get install mdadm" and "apt-get install curl".
Now you need to determine where in /dev/ the A drive is, mine was /dev/sdd, but you can run the debricker.sh to find it. Just do "sudo bash debricker.sh /dev/sdd" and see if your output matches below:
Number Start End Size File system Name Flags
3 15.7MB 528MB 513MB linux-swap(v1) primary raid
1 528MB 2576MB 2048MB ext3 primary raid
2 2576MB 4624MB 2048MB ext3 primary raid
4 4624MB 3001GB 2996GB primary raid
Once you found it then run the command "sudo bash debricker.sh /dev/sdd rootfs.img" and that's it. I was able to get my 6TB My Book Live Duo debricked using this method.
Here's the script:
#!/bin/bash
#
# The purpose of the script is to reinstall the operating system (debrick) on
# a harddrive that has been extracted from the housing of a WD MyBook Live.
#
#help screen
if [ $# = 1 -a "$1" = "--help" ]; then
echo "
standard use of script is:
sudo ./debricker.sh the script will find out what disk to use, it will not
touch the partition tables and therefore perserves data.
it will look what the newest version of the firmware is
via internet and then search for it in current folder or
subfolders. if none is found it will download one.
possible options are:
/dev/sd? path to the disk from mybook live. if not given, the script
will figure it out on its own.
/*/*.img path to the firmware that will be written to the disk. if
not given, the script will search for and then download it.
destroy script will rewrite the partition table of disk,
this will not perserve data, must match /dev/sd?.
example
sudo ./debricker.sh /dev/sda /firmwares/mine.img destroy
