Hello out there.

Lately i recovered a lot of drown harddisks from people here in the area. The most are recoverable after cleaning. But now i got a WD My Cloud from a college here. The My Cloud is a strange Network Attached Storage device, somehow only usable when online. Well it won't get online, the LED's on the NIC are flashing but it won't show up in the DHCP-list from the router. So i connected the Harddisk (a 4TB WD RED) directly to a PC (Windows 10 21H1 and Linux Mint 20.2), the harddisk is seen, but the partition type is unknown. So it is not a default Ext3 or Ext4. Or the partition table is broken do to the power failure.

Does someone has any idea?

Try UFS explorer it tends to do better with the more obscure file structures.

I would clone it as a first step, then work on the clone...

A clone would be a good idea, but unfortunately i don't have a 4TB hard disk atm.

I tried the UFS Explorer, it sees the harddisk and Partitions but it cannot access the partition containing the data. I'll try more tomorrow.

Huh? What does this even mean? It tells you it can not access the partition? Or you can access and it does not show data?

Then buy a 4TB drive.

All the partitions are seen by the software, but after clicking on the biggest one, it tells me it cannot open the partition.

Also tried testdisk, here it also sees all partition, but cannot access it.

I tried to receive any information trough the network port, but there is non. I used wireshark to sniff on the network, but there is none coming from the WD, although the led's on the nic are flashing.

These are the partitions shown in Linux:
Code:
Festplatte /dev/sda: 3,65 TiB, 4000787030016 Bytes, 7814037168 Sektoren
Festplattenmodell: WDC WD40EFRX-68W
Einheiten: Sektoren von 1 * 512 = 512 Bytes
Sektorgröße (logisch/physikalisch): 512 Bytes / 4096 Bytes
E/A-Größe (minimal/optimal): 4096 Bytes / 4096 Bytes
Festplattenbezeichnungstyp: gpt
Festplattenbezeichner: AA57E45C-3311-41A5-A289-5E56129BCE23

Gerät       Anfang       Ende   Sektoren Größe Typ
/dev/sda1  1032192    5031935    3999744  1,9G Linux RAID
/dev/sda2  5031936    9031679    3999744  1,9G Linux RAID
/dev/sda3    30720    1032191    1001472  489M Microsoft Basisdaten
/dev/sda4  9428992 7814035455 7804606464  3,6T Microsoft Basisdaten
/dev/sda5  9031680    9226239     194560   95M Microsoft Basisdaten
/dev/sda6  9226240    9422847     196608   96M Microsoft Basisdaten
/dev/sda7  9422848    9424895       2048    1M Microsoft Basisdaten
/dev/sda8  9424896    9428991       4096    2M Microsoft Basisdaten


The /dev/sda4 is the one containing the Data, at least i hope so, it is the biggest one.

fsck tells me, it cannot read the Superblock

Code:
roman@roman-PH67A-D3-B3:~$ sudo fsck /dev/sda4
fsck von util-linux 2.34
e2fsck 1.45.5 (07-Jan-2020)
fsck.ext2: Eingabe-/Ausgabefehler beim Versuch, /dev/sda4 zu öffnen

Der Superblock ist unlesbar bzw. beschreibt kein gültiges ext2/ext3/ext4-
Dateisystem. Wenn das Gerät gültig ist und ein ext2/ext3/ext4-
Dateisystem (kein swap oder ufs usw.) enthält, dann ist der Superblock
beschädigt, und Sie könnten versuchen, e2fsck mit einem anderen Superblock
zu starten:
    e2fsck -b 8193 <Gerät>
oder
    e2fsck -b 32768 <Gerät>

There's a tutorial on the ufsexplorer website for the wd my cloud, did you follow it ? https://www.ufsexplorer.com/articles/how-to/recover-data-wd-my-cloud-home.php

As others have said - don't work live, not on a customers device. Hard drives are cheap data is not, clone the drive just in case something goes wrong.

i am not sure this one is based on restsdk, it has too few partitions for that (at least compared to what i have seen).

+1 for Luke, buying a 4TB disk in such case should not be a limitation. Especially if you are running invasive sw like fsck.

Hmmm it is working now. Strangely the Partition was marked as "MS DATA". I changed the partition type to "ext3" using testdisk, corrected the superblock and i was able to access the data. At the moment it is copying the data. The Filenames are normal, so not as mentioned in a strange format.

And.. yes.. normally i make a clone.

I tried UFS on my brothers "My Cloud Home" and it did see the data with the correct structure and theoretically I can restore his files that he accidentally deleted but the problem is that it is way too expensive as €699.95 is way too much and we can never afford it to retrieve his accidentally deleted data.
It is personal data so there is no company or business owner to pay for it and my brother sure can't.

Is there another tool moderately priced that does understand the "My Cloud Home" data structure??

Thanks in advance.

You either buy the professional tools or you pay a professional with the tools.

I used Testdisk and it worked perfectly.

I love Test Disk, did it view the deleted files using the correct file structure or did it see the sql file structure?

Thanks.

After setting it to Linux ext3 on the big data Partition, it saw the correct file structure. Somehow the MBR got rewritten at the moment i connected it to the PC and all the partitions shown as "MS Data" instead of ext3.

That was brave. Cloning it first would be safer before using Testdisk. I can't recall, but I think with Testdisk you can back up before you commit changes in case it made it worse.

There's always Recovery Explorer Standard or Pro by the same guys. It's a free trial and cost much much less than UFS Pro for personal use.
