I have recently built myself a Hackintosh running MacOS X El Capitan, but along side the Mac disk, I have a number of other Windows disks. Unfortunately, some of these disks have some weird and wonderful partitioning that  only Windows can understand.

As a result, whenever I boot up into my MacOS X build, I constantly get prompted with a message stating The disk you inserted was not readable by this computer with options to Initialize, Ignore or Eject.

This guide explains how to use diskejectd to avoid this message from popping up every time you boot up the machine.
