I just acquired a WD My Book on my Mac running 10.11.6 and went to format the My Book for OS X Extended (Journaled), following the instructions on the WD support site. Those instructions say to use Disk Utility to erase the volume and reformat the drive. That is incorrect. One needs to erase the Drive and reformat that. (Of the two icons that appear in Disk Utility the drive icon is the upper one and the volume icon is the lower one.) When one selects (clicks on) the drive icon, a dialogue opens for entering the Name (the name of the volume), Format (of the drive - usually OS X Extended (Journaled)) and Scheme (select GUID Partition Map for a bootable Mac format) and then click the Erase button.
Hi,
Thanks for bringing this concern to our attention.
We will pass this to the correct department.
Thank you, thank you, thank you, THANK YOU!
John Beare - a thousand thanks for yr info -
it’s not noted anywhere on WD site & could not format my (new) drive till I chanced upon yr entry -
now able to use this product instead of returning it in frustration -
again, thank you -
I have a Mac Sierra 10.12.6. I purchesed the My Passport for Mac. It only backs up if I restart the computer. It backs up once then I get the message. “Time Machine couldn’t back up. An error occurred while creating the back up folder.” I have called WD 4 times. They keep having me reformat it.the last time they did create a folder but and it backed up, but it wont now. I thought maybe you had some idea what is wrong?? Thanks for any help you can give.

Sorry, I can’t help. I still use El Capitan (10.11.6). I don’t, and have never used Time Machine for backup. I use ChronoSync; more user friendly and flexible and can make bootable backups.
By the way, make sure you format the drive with GUID partition map.
This worked for me
