Tips and Tricks Recovery if control electronics is broken

How to recovery a single MyCloud disc after failure of control electronics.
Network card broken after lightning stroke.

I’m not reliable in case of any data loss in case this procedure won’t work with your data drive.
Testet only on my broken single 2TB WDMycloud.

Prerequesite:

SATA USB adapter, Linux based system (i.e.: Raspberry PI), some *nix (*=U/Li) know how.

How-To
Open the MyCloud housing, remove control electronics and all screws from disk drive.

Place disk in an external SATA adapter connected via USB to Raspberry Pi (in my case).

Disk will be automounted:

/dev/sda4 on /media/pi/02129f5b-a859-435f-b34a-17b49c9a6750 type ext4 (rw,nosuid,nodev,relatime,uhelper=udisks2)

In your case 02129f5b-a859-435f-b34a-17b49c9a6750 wil be different.

cd  /media/pi/<your individual number>

    pi@raspberrypi /media/pi/02129f5b-a859-435f-b34a-17b49c9a6750 $ ls -l

Example to revover data in directory PI.

drwxrwx---+ 24 root   pi 4096 Jan 23  2019 PI

cd into the directory PI will not work -> permission denied.

sudo chown -R pi:pi PI 

And you have access to all date in PI. Continue for all other shares. Access to public is possible without any changes.

Check necessary ownership if you are on any other Linux based system. pi:pi only works using a Raspberry PI.
