Reading from a Removed Harddrive from WD MyCloud

#1

I have a hard drive that was removed from an old WD MyCloud device. This was a NAS one generation before they actually started calling it MyCloud if that makes any difference.

Question is, what operating system will be able to read this drive? I’ve tried plugging it into a Windows 10 machine as well as OSX El Capitan and it shows up as unformatted.

Thanks

The first generation and second generation My Cloud hard drives use Linux (gen 1 uses Debain, gen 2 uses BusyBox on top of Linux).

Generally one can use a Linux Live CD, like the popular Ubuntu (http://www.ubuntu.com/download/desktop), to boot their PC and read from and write to a WD My Cloud hard drive attached to the computer.

Great! Thanks for the help. I’ll give that a try tonight.

I got a mount error when I tried this…

zero exit status 32: mount: wrong fs type

Ran fdisk -l and parted -l

sudo fdisk -l

Should be able to mount -t ext3 /dev/sdc4

RAC

Edit Why did it remove the mount point I put it in < mount point > Apparently you need a space after the < character.

#6

Tried this and got:

mount: can’t find /dev/sdc4 in /etc/fstab

#7

You need to specify a mount point, too.

Something like

mount -t ext3 /dev/sdc4 /some/folder/to/mount/to

Seen as HTML tag.

Always use the code formatting </> when posting code snippets; saves that sort of problem.

I recently found a way to complete this and it’s not too complicated.

I found this article, which helped out considerably. https://ahelpme.com/linux/recovering-md-array-and-mdadm-cannot-get-array-info-for-dev-md0/

I ran these commands and had success.

sudo mdadm --assemble --scan --verbose

sudo cat /proc/mdstat

once you figure out which disk you want to mount…

mount /dev/md# /mnt/point
