I have My Cloud Gen2 6TB I removed the hard drive and formatted it and now I want to reinstall the software on it I don’t have the files or the way to do that. I need help with that. Thank you.

Search this subforum and the OS5 My Cloud subforum for “unbrick”.

There are a number of past discussions showing various ways to “unbrick” a second gen single bay My Cloud (not My Cloud Home, that is a different device).

One method by user Fox_exe that some have successfully used:

If you followed the user Fox_exe directions linked above. Did you follow the initial steps to create the various partitions on the My Cloud hard drive then create the swap file and set the user data partition to EXT4? You must create those partitions and their sizes exactly as indicated in those directions along with create the swap file and set the user data partition (sda3) to EXT4.
