My Passport for Mac - New and not working

Is there a program I need to install to get a new MPFM to work using Yosemite 10.10.3?  It shows up when I plug it in,  but when I try to do a TimeMachine back-up it fails after a couple of hours (I have tried twice).  I simply plugged it in–was I supposed to do some sort of an installation or upgrade before using?  

Hello,

This should not affect the way the drive works on the computer. what you can try to do is changing ports or USB cables, but there is no software that could be needed to make the device work properly on your Mac. Do you only get this issue on this computer?
