Disk Utility format types.

Disk Utility has 4 format types on my Mac:

  • OS X Extended (Journaled)
  • OS X Extended (Case-sensitive, Journaled)
  • MS-DOS (FAT)
  • ExFAT


It also has schemes for when you erase a drive:

  • GUID Partition Map
  • Master Boot Record
  • Apple Partition Map


What does each thing mean, and when should I be using each thing. Thanks

MacBook Pro with Retina display, OS X Yosemite (10.10)

OS X Extended (Journaled) is for casual Mac user

OS X Extended (Case-sensitive, Journaled) for using with Mac Servers

MS-DOS (FAT) outdated MS file system, can be used for PC/Mac compatibility but with files less than 4Gb

ExFAT more modern MS file system any file size can be used


GUID for modern Macs and Windows PC

MBR for old Windows PC

Apple Partition for old PowerPC Macs
