'How to format an external hard drive Mac? What format system to use when reformatting my storage drive for a Mac?'

This is a frequent question asked by first-time, as well as the not-so-tech-savvy, macOS users. Learning how to format an external hard drive Mac is essential. Because saving all your data on the Cloud is nice and all, but physical storage is still popular. Especially if you don't have a stable internet connection or if most of your files are large.

Luckily, you don't have to learn rocket science to be able to format an external hard drive for Mac or PC. The operation is pretty straightforward. When it comes to your iOS device, we have listed two methods for you, read below and explore more.

Part 1: What Is the Best Format for External Hard Drive Mac?

The first step to formatting your external drive for a Mac computer is choosing the right format. There are four possible choices:

  • APFS (Apple File System)
  • HFS+ (Mac OS Extended)
  • exFAT (Extended File Allocation Table)
  • FAT (MS-DOS)

To understand which is the best for you, let's have a comprehensive overview of each of them.

1. Apple File System

The APFS was first introduced in 2017 as a replacement for the HFS+. Nowadays, all new Macs come with the operating system preinstalled on APFS, as this system is optimized for use with SSD and flash storage drives. However, it still works with traditional HDD drives too.

This is the best format to pick if you have an external SSD or USB flash drive that you don't intend to use with a Windows device.

The biggest strength of this system is the speed, as well as the encryption and metadata handling. However, you won't be able to use this system with Time Machine.

2. Mac OS Extended

The HFS+, or Hierarchical File System plus on its real name, was the main file system used for Mac until 2017.

This type of file system is suitable to use with both HDD and SDD drives, but the latter will perform slightly better with the APFS mentioned above. If you have an older Mac, though, choosing the HFS+ is your best bet.

In general, all external drives formatted to HFS+ work nicely with older Mac versions but are incompatible with Windows.

3. Extended File Allocation Table

Designed by Microsoft, the exFAT is a good choice if you plan to use the external hard drive with both macOS and Windows systems. Yet, you won't get top performance on either. This choice is more appropriate for USB flash drives, although you can still use it for SDD and HDD units too.

The main issue with exFAT is that your drive will be more prone to fragmentation when used with Apple devices and is less stable than NTFS on Windows. If you really have to share the drive between Mac and Windows machines, that's your best option though.

4. MS-DOS

Macs also support FAT32 drives, marked as FAT in Disk Utility. This format should be avoided at all costs unless you're dealing with a really old Windows computer, which you really have to use in parallel with your Mac system.

Typically, there is no reason to choose this option unless you're planning to use the external hard drive on a Windows XP or earlier machine.

Part 2: How to Format an External Hard Drive Mac?

Now that you know which format to choose, it's time to learn how to format an external hard drive for Mac. There are essentially two methods, with Disk Utility or Time Machine function.

Note: If you plan to format an older external drive, perhaps one you used with another device, make sure to backup all data before proceeding. Formatting is a permanent procedure that can't be reversed. While there are data recovery software you can use if you lost data, it is always better to prevent.

That said, here's how to format an external hard drive Mac:

Method 1: Format Mac Hard Drive with Disk Utility

Disk Utility is a utility application proprietary to macOS that is used to both format and manage internal and external disks. Here's how to use it:

Step 1 Connect the external hard drive you want to format to your Mac, then start the Disk Utility app that you can find under Applications -> Utilities.

Step 2 On the left side of the Utilities screen, find the name of the external hard drive you want to format and select it. Then, on the top side under the Disk Utility, click on the Erase button.

Step 3 Follow the on-screen prompts to select the desired file system and allow the drive to format. That's it! After the process is complete, you can either start using the drive or choose to create partitions on it.

Method 2: Format Mac Hard Drive with Time Machine

Formatting an external hard drive with Time Machine is as easy as formatting it with Disk Utility. Time Machine, however, gives you the possibility to create an automatic backup of the data on your hard drive before formatting it.

Before you proceed, therefore, you should first set up the external drive to use with Time Machine. To do this, open System Preferences and select Time Machine after you've connected the external drive to your Mac.

Now, click on Select Disk and select the desired drive from the list. Click on the Use Disk button. At this point, the system will run an automatic backup two minutes after you've clicked on the Use Disk button, or you can proceed with the formatting if the hard disk is empty.

To format an external hard drive for Mac with Time Machine, you must follow the steps below.

Step 1 Open Finder, Applications, then go to Utilities and Disk Utility.

Step 2 Follow the steps above to format the drive, and then you can use it with Time Machine on your Mac system.
