    Hi,

    Cant find this answer on the forum so thought id post.

    Just bough a new HDD which i want to formate to HFS+ which i gather is the best for mac only use and time machine.

    However when i go to disk utility HFS+ isn't a formate option? I get the below options. Im guessing the first is HFS+ but wanted to check.

    Mac OS extended (journaled)
    Mac OS extended (journaled, encrypted)
    Mac OS extended (case sensitive, journaled)
    Mac OS extended (Case sensitive, journaled, encrypted)
    ExFat
    Win NT filesystem (compressed)
    Win NT filesystem
    MS-DOS (FAT)

    Thanks
    James

    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 ($19.95) (Best Choice for Lion and Mountain Lion)
      • For Mac OS X 10.5 and later, including Lion, FUSE for OS X
      • 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), which is an enhanced version of NTFS-3G with faster performance.
      • Native NTFS support can be enabled in Snow Leopard and later versions, 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.

    Just a small correction, to avoid future confusion. What you mean and saw in Disk Utility and Mister GGJstudios listed in his last reply are file systems, or as Mac OS X calls them "Formats".
    File types, or file formats, are the container for files, often recognisable by their suffix, like .doc, .txt, .jpg, .avi, .mov, .psd and so on.
