  • Find your WD drive on your computer, look at the partition sizes and find the one that has a similar size as your WD MyCloud. For me, it was /dev/sdb with a size of around 1.8 TB.
fdisk -l
  • Install software for RAID devices
apt-get install mdadm
  • Mount RAID partitions
mdadm --stop /dev/md*
mdadm -A /dev/md0 /dev/sdb1 /dev/sdb2

dd if=kernel.img of=/dev/sdb5
dd if=kernel.img of=/dev/sdb6
dd if=config.img of=/dev/sdb7
dd if=config.img of=/dev/sdb8
dd if=rootfs.img of=/dev/md0

Re-attach WD Drive⌗

  • You can shut your computer down and remove the WD drive.

  • You don’t have to assemble the device completely right now, you can simply connect the plate to the drive and attach a LAN / power cord to it.

  • It should start up and show a yellow light.

  • You should see a green light in a while, which means Debian has started properly.

  • You can now ssh into your MyCloud device.

ssh root@192.168.X.XXX # replace with your IP

  • The default password for the root user is mycloud.

  • DO WHATEVER YOU WANT WITH YOUR NEW LINUX BOX! : )

WARNING: Executing apt-get upgrade sometimes bricks the device and should avoid it.
