2. Mac Os Extended Journaled Format

Summary :

HFS+ vs APFS Up until recently, HFS+ was the only file system supported by macOS and OS X. However, with the launch of the newest macOS High Sierra, Apple introduced a new drive type called Apple File System (APFS). HFS+ HFS+ was first introduced in 1998 with the launch of Mac OS 8.1 back when Apple made the switch to Intel-based processors. Mac OS Extended vs Mac OS Extended(Journaled) The Mac OS Extended is a file system that is also known as HFS Plus. This operating system can either be journalled or not, each with its own pros and cons. Journalling is not exclusive to the Mac OS as other operating systems are also capable of having a journalling system. Thanks, Helpful. Good idea running first aid’. Please- read your Application Vendor’s help file before considering a conversion. Carbon Copy Cloner current release (5.1.7) recommends ‘Mac OS Extended (Journaled)’ format for ‘spinning platter based backup devices’.

How much do you know about APFS vs Mac OS Extended? Which Mac file system should you choose? How to format hard drive for Mac? If you have similar questions on your mind, please read this page carefully to find answers; the main differences between APFS and Mac OS Extended file system and several ways to format a hard drive (internal/external) on Mac will be introduced.

Mac (formerly known as Macintosh) refers to the personal computers that are designed, manufactured, and sold by Apple Inc. MacOS is one of the most popular operating systems in the world; it’s the main competitor of Windows.

Common Mac file system includes:

• APFS (Apple File System): the default file system used in macOS 10.13 and later versions.
• Mac OS Extended: the file system used in macOS 10.12 and earlier versions.
• FAT (MS-DOS) and exFAT: the system systems that are supported by both Mac & Windows.

So you may ask what are the differences between APFS and Mac OS Extended, right? The following content first discusses on APFS vs Mac OS Extended; after that, it will tell you how to format a hard drive for Mac in several different ways.

Part 1: APFS vs Mac OS Extended

In this part, I’ll first introduce APFS and Mac OS extended to you. Then, I’ll compare these two file systems used on Mac for you in brief.

What Is APFS Format

APFS (the full name is Apple File System) is a proprietary file system released by Apple Inc. It can be used on different devices running macOS High Sierra (10.13) and later, iOS 10.3 and later, all versions of iPadOS, watchOS 3.2 and later, or tvOS 10.2 and later. APFS is a new file system which was originally designed by Mac to fix core problems of Mac OS Extended.

What Is Mac OS Extended (Journaled)

Mac OS Extended, also known as HFS+, HFS Plus or HFS Extended, is actually a journaling file system released by Apple Inc. It was released in 1998 to replace HFS (Hierarchical File System, also known as Mac OS Standard or HFS Standard), which is the previous primary file system in Apple computers. Two main advantages of HFS+ when compare to HFS are: a. it gives support to much larger files; b. it uses Unicode for naming items.

Part 2: Which Is Better, APFS or Mac OS Extended

APFS vs HFS+ vs HFS:

APFS file system was announced in June 2016 to replace HFS+ (also known as HFS Plus or Mac OS Extended); the latter was used on all Mac computers as the primary file system since 1998 to replace the previous HFS.

Choose APFS for SSDs & Flash Storage Devices

When compared to Mac OS extended, APFS has been optimized a lot in terms of encryption, so it’s more suitable for flash and solid-state drive storage. APFS becomes the default file system for both for SSDs (Solid State Drives) and flash drives.

• In 2016, APFS was first released by Apple to replace Mac OS Extended (the previous default file system on Mac); it carries all sorts of benefits you can found in Mac OS Extended.
• A partial specification for APFS was published by Apple in September 2018 to allow the read-only access to APFS drive on even unencrypted and non-Fusion storage devices.

But don’t worry, you can still use the APFS on mechanical and hybrid drives.

To gain quality but free USB data recovery service, you should use MiniTool Power Data Recovery Free Edition; this post tells you how to recover USB data.

There are two main highlights in APFS.

1^st: fast speed. Copying and pasting a folder on APFS drive can be finished in an instant since the file system points to basically the same data twice.

• There are huge improvements in metadata so that many actions can be performed quickly; for example, confirming how much space the target file/folder takes up on an APFS drive.
• The reliability is also improved a lot. Users don't encounter corrupted files as often as they used to.

2^nd: reverse compatibility. If you are running 2016’s macOS Sierra or the later versions of macOS, congratulations, you have both read and write access to APFS, HFS +, and HFS file system. However, for users who run an older Mac (or a Windows operating system), they are not allowed to write to APFS-formatted drives.

Pros & Cons of APFS

Main advantages of APFS:

• It’s able to create point-in-time snapshots for users.
• APFS allows users to encrypt the full disk by using a single or multi-key so as to enhance the security.
• The checksums are used to ensure the integrity of metadata.
• It creates new records, instead of overwriting the existing ones, in order to avoid metadata corruption; the records may be corrupted because of system crash or other reasons.
• The storage management of APFS is more efficient than HFS+, resulting in helping users get additional free space.
• Users don't need to write changes twice by choosing APFS over HFS+; this will increase the system performance on some devices.
• The clones or multiple copies of the same file are allowed; it will only store the changes as deltas. This helps to reduce storage space greatly when users copy files, make revisions, or do other things.
• The APFS drive is generally more stable and reliable than the previous HFS+ or HFS drive.

Main disadvantages of APFS:

• Compression is not allowed on an APFS drive.
• It gives no support to the Fusion drives.
• The NVRAM (Non-volatile Random-access Memory) can’t be used even for data storage.
• The Checksums used are only available for ensuring integrity of metadata (that of user data can’t be guaranteed).
• You can only access the encrypted volumes from another other computer which runs macOS High Sierra.
• The biggest disadvantage of all seems to be: APFS isn’t compatible with Time Machine till now. That’s why users are told to make backups on Mac OS Extended drive unless they use a third-party backup tool rather than the built-in Time Machine.

Choose Mac OS Extended Journaled for Mechanical Hard Disks

Mac OS Extended (HFS+) is the default file system for all Macs from 1998 to 2017, until the new APFS replace it. Till now, it’s still the default file system for both mechanical and hybrid hard drives. You should keep it unchanged while you install the macOS or format external hard drive Mac. The HFS+ is a better choice than APFS on even current mechanical and hybrid hard drives.

Besides, you should definitely choose Mac OS Extended when you reformat external hard drive Mac considering that it may be used on older Macs running El Capitan or earlier versions of macOS. As you know, the new APFS file system is not compatible with these old macOS versions.

Pros & Cons of HFS+

Main advantages of HFS+:

• It gives support to the Fusion drives (which can’t be supported by APFS).
• It gives support to all versions of Mac OS X and macOS.
• You can encrypt volumes and then access them from any version of Mac OS X and macOS.

Main disadvantages of HFS+:

• There’s no point-in-time snapshot for users.
• The nanosecond standard is not used for Timestamps.
• The native file support for other file systems is too limited.
• The support to Mac OS Extended will be stopped on February 6, 2040.
• No checksum is used for metadata integrity or user data integrity.
• You can’t have concurrent access to the file system by a process.

Please ask yourself the following questions when you choose between APFS and Mac OS Extended:

• Are you formatting the internal disk or the external hard drive on your Mac?
• Which macOS are you running? Do you prepare to install macOS High Sierra or later?
• Is the Time Machine backup or bootable installer included in your daily schedule?
• Are you preparing to use the disk on another Mac or even Windows computer?

Bonus Tip: Choose exFAT for Hard Drives Used on Both Mac & Windows

Though the file system of main system drive on Mac is confined to APFS and Mac OS Extended, you can still consider exFAT (or the older FAT) when you format an external hard drive on Mac.

The most obvious benefit of using exFAT is that it can work with both Windows and macOS computers (you have both read and write access to the exFAT drive). Although there are solutions to read Mac formatted drive on Windows or read a Windows formatted drive on Mac, formatting drives to exFAT is still a convenient thing and an economical choice.

Part 3: How to Format Hard Drive for Mac

Users shouldn’t reformat the disk that built-in Mac causally unless they have special needs and they are professional enough.

Final Thoughts

Both APFS and Mac OS Extended are popular file systems supported by Mac computers. If you don't know which one is more suitable for you, please read part 1 and part 2 carefully (the advantages & disadvantages of these two Mac file systems are included). Part 3 teaches you how to format a hard drive for Mac by using the snap-in Disk Utility; besides, it offers an easy method for recovering data from a formatted drive on Mac. Hope this can help you decide which one to choose: APFS or Mac OS Extended, and prevent your important data from getting lost.

Disk Utility

Disk Utility is a disk utility on macOS operating system. It supports creating, splitting, merging, resizing, deleting and formatting partitions on the hard disk. Disk Utility only supports partition creation and formatting for Mac OS Extended (Journaled), exFAT, MS-DOS (FAT) and since MacOS High Sierra (10.13), it supports APFS.

If you are a Linux user or operating systems other than macOS, you probably use another tool. In another case, if you are using a Seagate, WD My Passport or any other hard drive that you previously partitioned with another tool. Disk Utility will report MediaKit reports not enough space on device for requested operation. This error occurs because the partitions created do not comply with Apple’s partition policy. In this case, you can use other tools instead of Disk Utility.

In this article, I will guide you to create a Mac OS Extended (Journaled) partition with GParted. If you want to install macOS High Sierra or later versions, just use the Convert to APFS feature on Disk Utility.

GParted

GParted is a well known disk partitioning program. It supports many partition formats such as FAT32, NTFS, exFAT, Ext4 and of course supports Mac OS Extended. We can use GParted to create Mac OS Extended partitions in just a few simple steps.

GParted comes pre-installed on many Linux distributions like Ubuntu, Debian, Linux Mint… If you already have GParted installed, just use it. If not, you can download GParted or 4MParted ISO files then integrate into AIO Boot. You should use these two operating systems, as they have pre-installed programs that support the format. If you use GParted on Ubuntu, Linux Mint or Debian, you need to install hfsprogs.

The format of Mac OS Extended is HFS+. There are some commercial softwares that support creating HFS + partitions on Windows, but GParted is free. Now we will create the HFS+ partition with GParted.

1. Run GParted and select the hard disk in the dropdown list at the top right. My hard disk is /dev/sda.
2. You can only create new partitions if your hard disk has unallocated space. Right-click on the unallocated space and select New. You can also format existing partitions to HFS+. Right-click the existing partition, select Format to, and then select hfs+. Or delete the existing partition to recreate it.
3. Select hfs+ in the File system. Then select and enter some information for the other items you want.
4. Click Add, then click Apply to apply the changes.

The Mac OS Extended partition created by GParted will not be journaled. However, we can use Disk Utility to Enable Journaling. Or use the following command to format Mac OS Extended to Mac OS Extended (Journaled):

/dev/sdaX is the partition you want to format.

Convert to APFS

From the MacOS High Sierra version, Apple announced a new file system called APFS. By default, macOS High Sierra can only be installed on an APFS partition. You can use Disk Utility to convert Mac OS Extended partitions to APFS without losing data.

If the Mac OS Extended partition is not Journaled, please journaled it first. Run Disk Utility, select the Mac OS Extended partition in the left column, then select File and select Enable Journaling.

Now you can convert Mac OS Extended (Journaled) partitions to APFS without losing data. Just select Edit and select Convert to APFS…

By using GParted with the simple steps above, we can easily create Mac OS Extended (Journaled) partitions and many other formats that Disk Utility does not support. If you need to create macOS High Sierra bootable USB from Windows, you can try Clover Boot Disk. Good luck!
