Change damaged HD - downgrade

My Cloud OS 3 Personal & Network Attached Storage My Cloud

Hi all,

I have a WD My Cloud 4TB, S/N WCC4ENEJ99ZA, which had the disk completely damaged. Now I plan to replace the disk, however, I don’t have a 4TB disk to test if the rest of the system is working. Since I only have one 1TB disk in hand, is it possible to install a 1TB disk in my WD My Cloud?

If possible, which way should I go?

Yes it is possible to change the hard drive within the single bay/single drive My Cloud. It’s called “unbrick” and there are a number of methods of doing so. Note that there are different directions for each version (first gen v4.x or second gen v2.x) so make note of which firmware version your My Cloud is.

User Fox_Exe has created general directions on how to unbrick each single bay My Cloud version that some have used with success to unbrick their My Clouds…

The main Fox_exe repositories for multiple My Cloud models can be found either here:
