    I tried to create a 3rd partition (OSX / Bootcamp / Linux) to see if a Linux distro would see it.

    It seems that this 3rd partition for Linux is not seen at all. How can I reclaim this space either for OSX or BOOTCAMP?

    I have a Time Machine for the OSX install. I would hate to have to reinstall Windows and start fresh with the games and what else on that partition.

    Fusion drives only allow one other partition to be made. How did you create the partition?

    I could be wrong on the following, but I believe the only way to end up with a "third partition" (or more than three) is to do the following:

    - "DE-fuse" the fusion drive (you must back up everything first)
    - Partition the HDD as desired.
    - "RE-fuse" the SSD to one of the HDD partitions (has to be HFS+ and probably should be "the first" partition on the drive)

    Result will be a fusion drive + 2 "standalone" partitions on the HDD.
