WD Passport Ultra on MacOS Sierra - Won't reconfigure - help please

I’ve just opened my latest Passport Ultra and tried to reconfigure in Disk Utility to use with my MacOS Sierra, and it’s ‘failing’ every time. The WD instructions I’ve just are for OS Sierra - is there some problem I’m unaware of?

Any help would be great please. I’m a professional photographer with no space now and I have a wedding to download…

I’d like either instructions to reformat, or exact details of an external at least 2TB hard drive that will work with my Mac.

Many thanks in advance.

Hello,

Click on the link below for instructions on how to format the drive.

Hello, I’ve followed these instructions and these are the ones I follow that give me the ‘fail’ message. I can’t get the first delete instruction to even work. Does it not work with OS Sierra?

Many thanks K
