MyCloud - Fried or still have some life in it ? - Symptoms mentioned

Hello,
I had an external MYCloud 4TB HDD which I connected after sometime to backup the data, however it wasn’t working properly. I took out the HDD and now installed it through the external Case and still can’t connect to it. Model of the specific HDD is WD Red - NAS Hard Drive. It hasn’t fallen or create any kind of noise while connected.

Here is what I’ve done so far

When I connect, I get this error
“The Disk you inserted wasn’t readable by this computer”

- Finder
It doesn’t appears in Finder

- Disk Utility
It does shows up in external but in form of multiple disks such as disk2s1 to disk2s2. Mostly 1-2 GB partitions with the biggest one of 3.99 TB. Filesystem is being shown as MS-DOS(FAT) When I click on First aid for either of the disks,it gives me the error of First Aid Process Failed with following error message


Running First Aid on “” (disk2s2)

Repairing file system.
Volume is already unmounted.
Performing fsck_msdos -y /dev/rdisk2s2
** /dev/rdisk2s2

Invalid BS_jmpBoot in boot block: 000000

File system check exit code is 8.

Operation failed…

I also clicked on mount but nothing.

- Disk Warrior
It doesn’t gives me an option to Rebuild with “Unknown Disk” shown. Overview has the following error message

Directory cant’ be rebuilt, the file system is unsupported. Advanced File System" Windows/PC".

- Disk Drill
Doesn’t even display the drive

Any idea on how to fix it or this is gone forever ?

mount /dev/sdX4 in linux and your files will be there.

When attaching the My Cloud hard drive to a Windows PC one has to use a Linux driver so the Windows PC can recognize the Linux formatted partitions on the My Cloud hard drive.

I typed diskutil list and here is what appeared

55%20PM

When I type mount /dev/disk2s2 it gives me the error that unknwon special file or file system
When i type diskutil repairvolume /dev/disks2s, i get the following

Hs-MBP:~ h$ mount /dev/sdx4

i know nothing about diskutil is it apple? do you have a linux system or get a live CD. Can macs mount ext4 formats?

I’ve tried it on Ubuntu. Here are the things I did

-mount /dev/sdb1 ( I found sdb1 from Diskutil)
mount : /dev/sdb1: cant find in /etc/fstab

I tried to do mkdir /mnt/mydrive, it’s giving me error of Permission Denied.

When I go on diskutil, it does display the HDD as unallocated space with entire HDD shown as free space.

try

mkdir /mnt/hdd1
mount -t ext4 dev/sdb1 /mnt/hdd1
cd /mnt/hdd1
ls

see if it will mount this way. (dev/sdb1 needs to be the 4TB)

fdisk -l

Thanks for being patient with me. Here are the results

mkdir /mnt/hdd1 - > just goes to next line
mount -t ext4 dev/sdb1 /mnt/hdd1 -> mount: /mnt/hdd1 : Special device dev/sdb1 doesn’t exist ( I’ve seen and it’s shown in the disk util though )
cd /mnt/hdd1 -> Just goes to next line

fdisk -l
Disk is being displayed now but it shows the following error messages

  • The backup GPT table is corrupt, but he primary appears okay so that will be used.

I can now see the HDD in the file system but it asks for a password . I’ve no idea what’s the username & domain is since i don’t remember setting one up. I do remember the password with admin username however it doesn’t give me any error and the pop-up keeps on appearing. It says password required for mbp.local

Can you post the full results of

fdisk -l
