So before you jump into conclusions, you need to. And hard disk errors can happen from both the hardware and software side of things. The small form factor means that WD My Passport repair is not the easiest one to do.
Everything about WD My Passport is great except one, reparability. Maybe at some point Western Digital will release a Windows Store App for the Passport Series, but until then treat like any other normal external hard drive. Your Passport Software will not work on Windows RT, you can access the drive through Explorer. Unfortunately, the WD troubleshooting website recommends things like buying another Thunderbolt to USB cord to try to get it to work. It reportedly works with OS Maverick and under but has problems initializing on Yosemite. Other reviews show the same problem but I had not seen them when I bought it. This would not work on my Mac with OS Yosemite. But a month a ago I changed the file format so it would open on my mac and it opened for about a week and then now it won.
