Hi,
I've lost all my data on WD MyBookLive 2TB as many others.
I've connected disk to Ubuntu using external SATA to USB adapter.
I've started with standard disk utility from Ubuntu, it shows
------------------------------------------------------
Disk: WDC WD30 EZRS-11J99B1 (0100)

gdisk utility shows:
$sudo gdisk -l /dev/sdb
GPT fdisk (gdisk) version 1.0.5
Warning! Disk size is smaller than the main header indicates! Loading
secondary header from the last sector of the disk! You should use 'v' to
verify disk integrity, and perhaps options on the experts' menu to repair
the disk.
Caution: invalid backup GPT header, but valid main header; regenerating
backup header from main header.
Warning! One or more CRCs don't match. You should repair the disk!
Main header: OK
Backup header: ERROR
Main partition table: OK
Backup partition table: ERROR
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: damaged
****************************************************************************
Caution: Found protective or hybrid MBR and corrupt GPT. Using GPT, but disk
verification and recovery are STRONGLY recommended.

Disk /dev/sdb: 1565565872 sectors, 746.5 GiB

Sector size (logical/physical): 512/512 bytes
Disk identifier (GUID): 0DA7894D-0CAE-4FE5-A883-3B134C5E4FE3

gdisk /dev/sdb with option v shows
Command (? for help): v
Caution: The CRC for the backup partition table is invalid. This table may
be corrupt. This program will automatically create a new backup partition
table when you save your partitions.
Problem: The secondary header's self-pointer indicates that it doesn't reside
at the end of the disk. If you've added a disk to a RAID array, use the 'e'
option on the experts' menu to adjust the secondary header's and partition
table's locations.
Problem: Disk is too small to hold all the data!
(Disk size is 1565565872 sectors, needs to be 5860533168 sectors.)
The 'e' option on the experts' menu may fix this problem.
Problem: GPT claims the disk is larger than it is! (Claimed last usable
sector is 5860533134, but backup header is at
5860533167 and disk size is 1565565872 sectors.
The 'e' option on the experts' menu will probably fix this problem
Problem: partition 4 is too big for the disk.
Partition(s) in the protective MBR are too big for the disk! Creating a
fresh protective or hybrid MBR is recommended.
Identified 6 problems!
Recovery/transformation command (? for help): p

Now I'm waiting for testdisk results.
Any advice or recommendation?
