  1. What volume formats are supported as startup volumes for mac os x?
    • Mac OS Extended (Hierarchical File System Plus, HFS+)—
    • Mac OS Extended, Case-Sensitive (HFSX)—
    • Mac OS Extended, Journaled (JHFS+) or Mac OS Extended, Case-Sensitive, Journaled
    • (JHFSX)—
  2. What volume formats are supported as read/write in Mac OS X?
    • Mac OS Standard (HFS) This is the legacy volume format used by the classic
    • Mac OS. This format, though a precursor to HFS+, is not supported as a startup volume
    • for Mac OS X.

    • File Allocation Table (FAT)— FAT is the legacy volume format used by Windows PCs and still used by many peripherals. This format has evolved over the years, with each progressive version supporting larger volumes; FAT12, FAT16, FAT32. Apple’s Boot Camp supports running Windows from a FAT32 volume, but Mac OS X itself cannot
    • start up from such a volume. Boot Camp is covered in Chapter 6, “Applications and Boot Camp.”
    • UNIX File System (UFS)— UFS is the legacy native volume format supported by Mac OS X. UFS served as the default UNIX file system for decades. Starting with Mac OS X v10.5, though, UFS volumes are no longer supported as startup volumes.
    • Further, Disk Utility does not support the creation of UFS volumes.
  3. What volume formats are supported as read-only in os x?
    • NT File System (NTFS)—Windows 7, Windows Vista, Windows XP, and Windows Server all use this as their native volume format. Once again Boot Camp supports running Windows from an NTFS volume, but Mac OS X itself cannot write to or
    • start up from such a volume. Further, Disk Utility does not support the creation of NTFS volumes.
    • You can add NTFS volume write support to Mac OS X by installing thefree and open source NTFS-3G and MacFUSE software bundle: http://macntfs-3g.blogspot.com.

    ISO 9660 or Compact Disk File System (CDFS)—This is a common standard for read-only CD media. Note, however, that “Mac formatted” CD media can contain HFS-formatted volumes.

    Universal Disk Format (UDF)—This is a common standard for read-only DVD media. Again, note that “Mac formatted” DVD media can contain HFS-formatted volumes.
