Disk Utility User Guide
Disk Utility on Mac supports several file system formats:
- Jan 11, 2015 Anyway, I have this 1TB external hard drive. And by default the format is in NTFS. I'm not getting the entire 1TB. When I formatted it to Mac OS Extended (Journaled) I was so amazed. I am getting the entire 1TB. I even plugged it on my Windows 8 computer. It worked great. Now, I am thinking of using Mac OS Extended (Journaled, Encrypted).
- Oct 04, 2016 A case-sensitive HFS+ volume is still better for compatibility with OS X than FAT or ExFAT, so it could be used as a transitory system. Apple has not disclosed yet whether they will make the switch to case-sensitivity with Apple File System, as that system is currently case-sensitive only.
- Mac OS Extended (Journaled) is the normal recomended way to format your drives, internal and external. I always format a new drive as Mac OS Extended (Journaled), immediatly and before use. If you wish to change to Mac OS Extended Journaled: you will need to reformat your drive.
- Jul 02, 2020 Choose Mac OS Extended (Journaled) for any disk that you plan to use as a Time Machine backup disk or as a bootable installer. Will you be using the disk with another Mac? If the other Mac isn't using macOS High Sierra or later, choose Mac OS Extended (Journaled). Earlier versions of macOS don't work with APFS-formatted volumes.
Apple File System (APFS): The file system used by macOS 10.13 or later.
Mac OS Extended: The file system used by macOS 10.12 or earlier.
MS-DOS (FAT) and ExFAT: File systems that are compatible with Windows.
Dec 17, 2018 But you cannot write this flash drive from windows PC once you have formatted it as Mac OS Extended (Journaled). You can read files though. OS X Extended (Case-sensitive, Journaled) Go for this type of filesystem if you really need it for some reason. For OS X Extended (Case-sensitive, Journaled), the word “File” is different than “file. Nov 03, 2019 The only difference is Encrypted encrypts the drive contents. When you are formatting in Disk Utility, it will ask you for a password for the device before the format begins. Once you do that, to access the data on that drive you will need the enc. If its ever a particular need for a DIT to use your drive on their Windows machine, format a drive as something they can read when the time comes. In the mean time use HFS+ on a Mac. (aka 'Mac Extended Journaled') Just make sure you an always afford to reformat a drive when you need to, and it's not a big problem.
Apple File System (APFS)
Apple File System (APFS), the default file system for Mac computers using macOS 10.13 or later, features strong encryption, space sharing, snapshots, fast directory sizing, and improved file system fundamentals. While APFS is optimized for the Flash/SSD storage used in recent Mac computers, it can also be used with older systems with traditional hard disk drives (HDD) and external, direct-attached storage. macOS 10.13 or later supports APFS for both bootable and data volumes.
APFS allocates disk space within a container on demand. The disk’s free space is shared and can be allocated to any of the individual volumes in the container as needed. If desired, you can specify reserve and quota sizes for each volume. Each volume uses only part of the overall container, so the available space is the total size of the container, minus the size of all the volumes in the container.
Choose one of the following APFS formats for Mac computers using macOS 10.13 or later.
APFS: Uses the APFS format.
APFS (Encrypted): Uses the APFS format and encrypts the volume.
APFS (Case-sensitive): Uses the APFS format and is case-sensitive to file and folder names. For example, folders named “Homework” and “HOMEWORK” are two different folders.
APFS (Case-sensitive, Encrypted): Uses the APFS format, is case-sensitive to file and folder names, and encrypts the volume. For example, folders named “Homework” and “HOMEWORK” are two different folders.

You can easily add or delete volumes in APFS containers. Each volume within an APFS container can have its own APFS format—APFS, APFS (Encrypted), APFS (Case-sensitive), or APFS (Case-sensitive, Encrypted).
Mac OS Extended
Choose one of the following Mac OS Extended file system formats for compatibility with Mac computers using macOS 10.12 or earlier.
Mac OS Extended (Journaled): Uses the Mac format (Journaled HFS Plus) to protect the integrity of the hierarchical file system.
Mac OS Extended (Journaled, Encrypted): Uses the Mac format, requires a password, and encrypts the partition.
Mac OS Extended (Case-sensitive, Journaled): Uses the Mac format and is case-sensitive to folder names. For example, folders named “Homework” and “HOMEWORK” are two different folders.
Mac OS Extended (Case-sensitive, Journaled, Encrypted): Uses the Mac format, is case-sensitive to folder names, requires a password, and encrypts the partition.
Windows-compatible formats
Choose one of the following Windows-compatible file system formats if you are formatting a disk to use with Windows.
MS-DOS (FAT): Use for Windows volumes that are 32 GB or less.
ExFAT: Use for Windows volumes that are over 32 GB.
When you put a new hard drive in your Mac—or connect an external one using FireWire or USB—you need to decide how to partition the drive and what file system to put on it. The easiest way to do that is with the Disk Utility in Applications/Utilities. After you start it, Disk Utility shows a list of all available disks along with all the volumes (partitions) present on those disks on the left side of the window. If you want to keep things simple, just select a disk, click on the 'erase' tab and you can create a volume that uses the entire disk with a few mouse clicks.
If your needs are more complex, select the 'partition' tab. There, you can divide the disk into several partitions. The advantage of having multiple partitions is that if one fails, the others may be unaffected. The downside is that you need to think about the size of the different partitions and keep track of which files go where. And copying files from one partition to another is slow, even slower than copying from one disk to another. Keep in mind that disk access is fastest on the outside of the disk, where the first partition is located. Whether you decide to partition the disk or not, the 'options' button lets you set the type of 'partition scheme' for the disk. There are three choices:
- Apple Partition Map: this way of organizing a disk has been used with Macs for a long time. If you want to boot a PowerPC Mac from the disk, you need to use this partition scheme. However, you can't put any FAT (MS-DOS/Windows-compatible) partitions on the disk.
- Master Boot Record: this is how MSDOS and Windows organize a disk, so use this if you have an external drive that you also want to use with a Windows machine. It looks like you can also use the Mac OS Extended (HFS+) file system on disks with a master boot record, but it's unlikely that older Mac OS versions support this.
- GUID Partition Table: this is how Intel Macs organize their boot disks. You can put partitions with any of the supported file systems on a GUID disk, but only Macs running Mac OS 10.4 can access these disks.
In most cases, you'll want to use Mac OS Extended (Journaled) as the 'volume format' (file system). This supports all the Mac-specific functions such as aliases and resource/data forks. However, this isn't your only choice. Depending on the partition scheme, these are the file systems Mac OS 10.4 supports:
- Mac OS Extended or HFS+ is an improved version of Apple's Hierarchical File System from the mid-1980s.
- Mac OS Extended (Case Sensitive) is the same file system, but in this case, it treats file names that are the same but have different case as different. So the file text.txt is different from the file Text.txt and both can exist side by side. This matches the behavior of UNIX.
- Mac OS Extended (Journaled) is also HFS+, but it has an extra mechanism that avoids corruption of the file system when something bad happens, such as loss of power during a write operation.
- Mac OS Extended (Case Sensitive, Journaled) is HFS+ with a combination of case sensitivity and journaling.
- MS-DOS File System is the older FAT filesystem used with MS-DOS and Windows. Note that you can't have files of 4GB or bigger on a FAT volume.
- UNIX File System (UFS) is exactly what the name suggests. Don't use it unless you know you need to.
Mac Journaled On Windows
Use HFS+ with journaling if possible, especially on external drives. I've lost a lot of data because the FAT file system on a FireWire drive got corrupt after I accidentally turned off the drive while it was in use. After this, newer files started overwriting older ones, but I didn't find out until a month later. And don't format or partition an iPod using Disk Utility, because the iPod gets confused, even though it will function as an external drive.
Mac Os Extended Journaled Vs Case Sensitive Journaled
In addition to the file systems listed above that you can use to format your drives with, Mac OS X has various levels of support for the following file systems:
Mac Os Extended Journaled Vs Case Sensitive
- HFS: the original Mac file system
- NTFS: the Windows NT file system (read-only)
- ISO-9660 (with various extensions): the file system for data CDs
- UDF: the Universal Disk Format for DVDs
