WD My passport not mounting in mac!

So far none of the problems reported here were due to any firmware issues.  All the issues we found so far were due to either incompatible formatting, defective drives, defective cables, or defective usb ports.

I recommend that if you’re not sure what may be the cause of any issues you may be experiencing, please contact support for further help.  Below is the contact information for WD’s Support. You can contact them either by phone or email.
