I have a KWI USB external USB 320GB drive and two MacBooks. One MacBook Pro (Late 2011, OS X 10.10.3) and a MacBook Air (Early 2014, OX 10.10.3). When I plug the drive into the MacBook Air I am able to mount it. However, when I plug the drive into the MacBook Pro it doesn't show up in the Finder or Disk Utility. I've tried:

* Different USB ports
* Different cable
* Restarting
* Logging is as a different user (to verify it's not a incompatibility in something I've installed).
* Reformatting the drive to FAT

Anyone have any ideas?
