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

[mevora1]

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

---

Volume is already unmounted.

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

- 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.

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

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.

My Cloud dead, how to see content on Windows 10?

Hi! I don’t really know if this is the place to post this, but I would really really need some help. So one day I woke up and realized that my My Cloud 3 TB was glowing all red in the front. I didn’t think that is was such a big deal, however after trying to get it to connect through Wifi several times (for about 6 hours), I couldn’t get it working. I was so frustrated. My whole life is on the My Cloud. What I did notice under the procedure was that the Ethernet light didn’t blink at all. Whe…

I typed diskutil list and here is what appeared

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

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

[mevora1]

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.

[Vodka34]

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

[mevora1]

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

[Vodka34]

Can you post the full results of

fdisk -l
