Need more information. It your My Cloud a Gen1 or Gen2?
If the P/N ends with “-00” it is a first generation My Cloud.
If the P/N ends with “-10” it is a second generation My Cloud.
If you downloaded the 4TB img from one of the unbrick threads. It will not have your data files.
What is the problem with your device that you have to unbrick it?
I was impatient and unplugged it while it was doing a system reset or something… anyways it was working fine up until then and now, I get the “RED light of DEATH”.
Does the instruction that are on the thread that you got the 4TB img say that it will not
destroy the data partition? If the disk still has the correct partitioning. You really only need to restore
partitions one and two most likely.
Personal data is already backed up to other drives, so at this point it doesn’t matter. Luckily for me Ubuntu’s diskpart isn’t automatic or else I would have deleted my laptop’s drive instead of the MyCloud by accident
