    Hi, I was told to visit this forum for help regarding partitioning or anything Mac.

    So I'm currently waiting for the Haswell refresh of the rMBP. I haven't decided what size I want, more than likely the 15" for quad core ans possible dGPU and I know I'm getting 16GB. My SSD however, is undecided.

    I want either a 256 or a 512GB SSD. The size depends on what I can do.

    I want to partition the 512GB SSD into three parts. ~100GB for OS X, ~100GB for Windows 8, and the other ~300GB as storage that BOTH OSes can access. Is it possible? I read if you leave the 300GB partition as FAT32 you can use it across both, but files can't be larger than 4GB in FAT32. So that means no games installing to the partition, I could just stick games on the Windows partition or have 4 partition, a small ~100GB for games and ~200GB for files.

    Sorry if I'm explaining this badly. Is it possible?

    You could also use exFAT.


    Overview of the four major file systems (called "Formats" in Mac OS X) used on Windows and Mac OS X, compiled by GGJstudios. You can use Disk Utility to format any HDD to your liking.

    Any external hard drive will work with PCs or Macs, as long as the connectors are there (Firewire, USB, etc.) It doesn't matter how the drive is formatted out of the box, since you can re-format any way you like. Formatting can be done with the Mac OS X Disk Utility, found in the /Applications/Utilities folder. Here are your formatting options:

    HFS+ (Hierarchical File System, a.k.a. Mac OS Extended (Journaled) Don't use case-sensitive)

    NTFS (Windows NT File System)
    • Read/Write NTFS from native Windows.
    • Read only NTFS from native Mac OS X
      [*]To Read/Write/Format NTFS from Mac OS X, here are some alternatives:
      • For Mac OS X 10.4 or later (32 or 64-bit), install Paragon (approx $20) (Best Choice for Lion)
      • For 32-bit Mac OS X, install NTFS-3G for Mac OS X (free) (does not work in 64-bit mode)
      • For 64-bit Snow Leopard, read this: MacFUSE for 64-bit Snow Leopard
      • Some have reported problems using Tuxera (approx $36).
      • Native NTFS support can be enabled in Snow Leopard and Lion, but is not advisable, due to instability.
    • AirPort Extreme (802.11n) and Time Capsule do not support NTFS
    • Maximum file size: 16 TB
    • Maximum volume size: 256TB
    • You can use this format if you routinely share a drive with multiple Windows systems.

    exFAT (FAT64)
    • Supported in Mac OS X only in 10.6.5 or later.
    • Not all Windows versions support exFAT. See disadvantages.
    • exFAT (Extended File Allocation Table)
    • AirPort Extreme (802.11n) and Time Capsule do not support exFAT
    • Maximum file size: 16 EiB
    • Maximum volume size: 64 ZiB
    • You can use this format if it is supported by all computers with which you intend to share the drive. See "disadvantages" for details.

    FAT32 (File Allocation Table)
    • Read/Write FAT32 from both native Windows and native Mac OS X.
      [*]Maximum file size: 4GB.
    • Maximum volume size: 2TB
    • You can use this format if you share the drive between Mac OS X and Windows computers and have no files larger than 4GB.
