How can I reformat for macOS 10

Hi intrepidd ,

Maybe you should refer to the link given below in order to re-format the drive for Mac.

Thanks,That’s what I did. But like most instructions, it only tells you what to if everything goes OK.I kept getting an error message "Erase Failed " without any suggestions or help on how to resolve this problem.This is typical of instructions, it seems they never address problems that users encounter.
Anyway I called tech support and we repeated all the steps I had performed and received the same error message.Tech support suggested rebooting the system. For some unknown reason this fixed the problem.It would have been a lot better is this simple fix had been mentioned someplace in the instructions such as the one you referenced.
