Has anyone else tried to create a small partition on a Fusion Drive on a 2012 Mac? Disk Utility greys out the box to set my own file size, only allowing me to drag the graphic to set the size of the new partitions. This results in the smallest partition allowed of 67GB. Post paritioning, it actually achieves a partition of 120+ Gigs. That's crazy. I only need it to hold 100MB of files. Is everyone else finding the same thing? Anyone got any suggestions or has anyone found a third party tool that non-destructively allows you to create a partition on a Fusion Drive?
