I pulled out a HDD from the My Book Live (Western Digital) NAS because it doesn't connect anymore.

Product info: http://www.wdc.com/en/products/products.aspx?id=280

I am trying to recover data from the drive. Windows can't read the filesystem but I could see 4 partitions, so I booted into Ubuntu live.

The drive shows up on Linux but prompts this error and is not accessible:

Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sdi4, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so

I am a Linux noob so I need some help here.

With further research on Google, I am running TestDisk to analyse the drive. I don't know what partition type it is so I picked EFI GPT: Code :

[Intel  ] Intel/PC partition
>[EFI GPT] EFI GPT partition map (Mac i386, some x86_64...)
[Humax  ] Humax partition table
[Mac    ] Apple partition map
[None  ] Non partitioned media
[Sun    ] Sun Solaris partition
[XBox  ] XBox partition

Right now I am running "Analyse cylinder" on it using TestDisk and it's working through the 2TB drive slowly.

How should I go about accessing the data on the disk?

Got to access the data by mounting on to windows using Ext2FSD 0.48 patched with Ext2fsd-0.48-bb8

Step by Step from Windows 7 (Source):

  1. Download Ext2Fsd 0.48 (ext2Fsd.com).
  2. Before you installed it, you need to change the compatibility. Right click and choose Properties and set compatibility mode to Vista Service Pack 2 and run as administrator. Now you can install the Ext2Fsd-driver.
  3. Ext2Fsd only supports ext2 and ext3 formatted volumes. To make Ext2Fsd can read ext4-volumes, we should patch it. Download the patch from http://www.acc.umu.se/~bosse/ (Ext2fsd-0.48-bb8)
  4. Unzip the downloaded file. Open the folder fre and choose your architecture. (i386, ia64 or amd64)
  5. Copy ext2fsd.sys to Windows\System32\drivers. (Keep the original file as back-up)
  6. Restart your PC
  7. Now you can mount your ext4-drive, by opening Ext2Mgr and select your ext4-volume, which you want to mount. Choose a mount point!
