Asked to post question here from Community Forum.

Hi

May be a quick question because I'm keep getting error that saying could not save recovery key to Microsoft account.

I'm logging to Microsoft account and verified.

I have no problem backing up the key for OS drive.

On external or USB drive, micro SD on back on Surface of or instance, "save to Microsoft Account" option papers but it never success for those. 

Is that even possible?  Well, there is option available for start.
