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)
Size: 802 GB (801 569 726 464 bytes) :o Opps!
Partitioning: Unknown (PMBR)
------------------------------------------------------
fdisk utility shows:

$sudo fdisk -l /dev/sdb
Disk /dev/sdb: 746,53 GiB, 801569726464 bytes, 1565565872 sectors
Disk model: EZRS-11J99B1
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x00000000

Device Boot Start End Sectors Size Id Type
/dev/sdb1 1 4294967295 4294967295 2T ee GPT
--------------------------------------------------------
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
Model: EZRS-11J99B1
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!

Now I'm waiting for testdisk results.

Any advice or recommendation?

Your log already shows one inaccessible sector.
Your problems might not necessarily been caused by the WD security problem but by a failing drive.
Duplicate your drive using ddrescue as described in the manual and rerun smartmontools as broken sector information will have been updated afterwards.

Please document your recovery process using text and screenshots. So far I can't see what you did.

Any suggestion/ideas how to recover data from it?

Pavel, my best hint for you is to be more precise in descriptions! :roll:
As you wrote "2 TB" you managed to fool me successfully.

This is what you initially wrote:

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)
Size: 802 GB (801 569 726 464 bytes) :o Opps!
Partitioning: Unknown (PMBR)
------------------------------------------------------
I just looked up your drive. The WD30 EZRS-11J99B1 is a 3 TB drive !!!
and that won't work with a MBR type partition table because your drive has a logical sector size at the housing interface of 512 bytes.
That combination can only address approx. 2 TB.

To ensure maximum compatibility, WD assumably has put in some additional converter electronics that converted the 512 bytes into a sector size of 4096.
With that increased sector size, the MBR type partition table can adress 3 TB.

You probably left out the converter electronics when setting up your connection.
Hint: 3000GB (= 3 TB) modulo 2200GB = 800 GB.

You have one pending sector and although 44 °C is a allowed temperatur this drive (probably running at 5400 rpm) should rather run 10°C lower.

Buy yourself an expensive enterprise drive with >= 3 TB and a logical sector size of 4096 bytes (physical 4096 / logical 4096)
That should allow you to duplicate your drive directly using your described hardware configuration with your SATA/USB interface.

If you are running an old computer, test its abilities to deal with a capacity of >2 TB.
You can verify that by putting a partition on your new enterprise drive and running the windows software h2testw or the linux equivalent fff or 3f? (fight flash fraud). If the verify operation succeeds, your computer is ready to deal with drive sizes beyond 2 TB.

My fault, you can imagine how I felt when I've found lost of all my data.

Anyway, I bought new 3TB disk and took new HDD dock-station, that support >3TB disks. Clone my disk and now it's look better. For example, gdisk didn't find any error

pkolesni@pkolesni-HP:~$ sudo gdisk /dev/sdb
[sudo] password for pkolesni:
GPT fdisk (gdisk) version 1.0.5

Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: present

Found valid GPT with protective MBR; using GPT.

Command (? for help): v

No problems found. 31597 free sectors (15.4 MiB) available in 2
segments, the largest of which is 30686 (15.0 MiB) in size.

Command (? for help): p
Disk /dev/sdb: 5860533168 sectors, 2.7 TiB
Model: USB3.0
Sector size (logical/physical): 512/4096 bytes
Disk identifier (GUID): 0DA7894D-0CAE-4FE5-A883-3B134C5E4FE3
Partition table holds up to 128 entries
Main partition table begins at sector 2 and ends at sector 33
First usable sector is 34, last usable sector is 5860533134
Partitions will be aligned on 2048-sector boundaries
Total free space is 31597 sectors (15.4 MiB)

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

But I can't mount partition 4 using disk utility. Get error message in attach.
wrong fs type, bad option, bad superblock on /dev/sdb4, missing codepage or helper program, or other error (udisks-error-quark,0)

Any ideas how can I mount this partition and restore my data?

Cheers, Pavel

If you can't find content using the p-key ("list files") use Photorec or some other recovery software.
