Hello and welcome,

Sorry to hear that you cannot access your files. If you were using a RAID 1 setup, you should be able to recover your files by connecting one of the internal hard drives to a Linux PC, also check if one of the links below is useful.

Copy the good partition table from disk b to disk a

dd if=/dev/sdb of=/dev/sda count=1 bs=512

You could try installing gdisk too. It is very useful for fixing partition table issues etc

apt-get update

apt-get install gdisk

gdisk /dev/sda
?

and you should get some recommended option for a fix

same with sdb

gdisk /dev/sdb
?

Hello Ichigo,

i downalod R-Linux for Windows and try open drive file but faild so i scan it maybe can recover data at first it will take 2 days.

i plug my Disk A using USB to SATA bridge hope this isn’t problem.

Hello nfodiz,

both of partition tables for Disk A and Disk B is corrupted and for my bad luck i use spanning mode .

but i install new backup image for MyBookLiveDuo on diffrent hard disk to be able using debian os and try to plug Disk A on position of Disk B also plug Disk B on his position but no point

You will have to add the repo to /etc/apt/sources.list

It is available in the following repos

wheezy (admin): 0.8.5-1
Binary packages: gdisk
jessie (admin): 0.8.5-1
Binary packages: gdisk
sid (admin): 0.8.5-1
Binary packages: gdisk

So I would add the following repo

deb http://ftp.us.debian.org/debian/ wheezy main

Don’t forget to run apt-get update after you add the repo

refer to  http://www.rodsbooks.com/gdisk/gdisk.html for some documentation on using the program

http://community.wd.com/t5/My-Book-Live-Duo/GUIDE-Debrick-a-MyBookLive-DUO/m-p/544860/highlight/true#M3749

Guide 1 there should also get you going. In your case you would have to run it on disk a and b. It will not touch your data partitions and if they are ok the span should rebuild in 10 minutes or so.

I would try gdisk first and if that doesn’t work, try guide 1 from the link above on both disk to write a clean OS to both disks. After you install the OS on the first disk, shut everything down and hook up the second disk and follow the same process. Pop both drives back in the enclosure and cross your fingers.

please help me nfodiz.

I have a feeling you have a bad hard drive in there for the partition table to corrupt twice like that. I’m not sure from your post if you debricked again to fix this and it didn’t work or if you are looking for gdisk commands to do it?

There is a nice gdisk guide here which will walk you through the process

http://www.rodsbooks.com/gdisk/repairing.html

If you get it working again, I would get any data you need off there and RMA the unit
