If you do this in another order that I have described index in WD goes haywire and then it's just to start all over again. After this you can take the disk out of MyCloud and connect to PC SATA with the old disk to SATA and boot up in your USB Ubuntu, copy files from old to new disk. Can take 4-5 hours depending on disk size. When you put the HD back in WD hardware and start up have lots of patience it has to index everything.
Tips:
If your WD Cloud makes a lot of noise when not doing anything change the power supply. I also soldered a "2200uF for SM power supplies" inside on the power input.
