There is another term related to disk formatting and it is called reformatting. It is called high-level formatting as it is used to prepare the disk for different file system format.

Part 4. Different Formats of Hard Drive for Mac:
Mac Hard drives have wide support for formats but there are two major formats which are preferably used by the Mac users. It also depends on the macOS version you are using. The key point to consider is that the drives formatted with the newer versions won’t be recognized by the older devices. So, when you are formatting a USB drive, it will be ideal to choose the right format which is Mac OS Extended.
The supported Mac formats for the drive are explained below:
APFS:
The APFS format is optimal for Solid State Drive such as flash drives. Hence, if you are formatting a flash drive, you should definitely choose the APFS format. Along with the flash drives, this format is also faster and more reliable for Mac hard drives.
Mac OS Extended:
Talking about Mac OS Extended, it is perfectly suitable if you want to use a drive for backup. The Time Machine feature of Mac still doesn’t have support for APFS disk. In case you select this format, Time Machine will prompt you to reformat the drive.
When you are formatting disk on Mac, keep some things in mind. Never ever change the inbuilt format of a Mac drive.
Part 5. Tips for Formatting a Hard Drive on Mac:
Even though formatting doesn’t seem like a big deal, still it can be very helpful. So, it is important that you stay active and keep all things in mind. Here are some tips that might help you when you are about to format a Mac hard drive.
- Disk Utility in macOS Sierra and later chooses a compatible format for you automatically. But you should know the default format for your drive. It is advised not to change the default format of a Mac hard drive under any circumstances.
- You can check the format of a drive inside the Disk Utility Menu bar. Just click on the Get Info option and you’ll know the current format a drive is using to store files. Open the System information and select the storage. In the right side panel, you will see the respective format for each volume on your Mac.
- If you want to erase your disk before you install the latest High Sierra on your Mac for the first time, then opt out for the Mac OS Extended format. During the installation of OS, the macOS installer will automatically decide whether to use APFS or Mac OS Extended for the disk.
- You can also use the FAT32 format on Mac for USB drives if you wish to use it on both Mac and Windows. The FAT32 format can be read and written on both OS and hence it is the most versatile format for use.
- If you wish to transfer big files from Windows to Mac, you’ll still have an alternative, i.e. exFAT. This format doesn’t have a file limit but it can only be read on Mac OS X Snow Leopard or later.
So, before you pick out the format, look out for the advantages and the disadvantages of the formats to choose the optimal format for Mac. The Windows supported format is usually listed as MS-DOS format in the list of formats.

Looking for a way to install and run OS X on an external hard drive? This can be useful for a couple of different reasons. Firstly, it allows you to run another copy of OS X without needing any additional Mac computer.
Also, since you can run a full copy of OS X on the external drive, it can be used for troubleshooting purposes on other Macs or it can be as a kind of virtual OS X. I’ve already written about how you can install OS X in VMware Fusion, but that takes up space on your Mac. Using an external drive, you can save space on your Mac, though it might be a bit slower if you are using USB 2.0.
In this article, I’ll walk you through the requirements and steps to install OS X onto an external hard drive.
Format External Hard Disk
The first thing you’re going to need to do is format the external hard drive properly. The file format has to be Mac OS X Journaled and you have to use the GUID partition map. To do this, open Disk Utility and connect the drive to your Mac.
Under External in the left hand menu, click on your external hard drive and then click on the Erase button. Make sure you backup any data before you erase the drive. When you click Erase, a dialog will pop up where you can configure some options.
Give your drive a name, choose OS X Extended (Journaled) for Format and GUID Partition Map for Scheme. It should only take a minute or two for the drive to be erased and reformatted. Now your drive is ready for OS X.
Install OS X
There are two ways you can install OS X on to your external hard disk: by reinstalling OS X from the OS X Utilities repair screen or by downloading OS X from the App Store and running the installer. I’ll show you both methods in case one isn’t working for you.
The easiest way is to download OS X from the App Store. Once you open the App Store, you’ll see a link on the right for the latest version of OS X (El Capitan as of this writing).
Go ahead and click the Download button to start downloading the installer. Note that if you already have that version of OS X installed, you’ll see a popup message appear asking if you still want to continue or not. Just click Continue.
Once it has been downloaded, just double-click the installer, which will be located in the Applications folder.
Keep clicking past the license agreement, etc., until you get to the screen that asks you which disk to install OS X on. By default, it is set to MacBook.
Click on the Show All Disks button and you’ll see an icon for the different disks and partitions on the Mac. I named my external hard drive OS X and that shows up in the middle.

You can also tell it’s an external hard disk because it uses the icon with the orange hard drive. Click Continue and then follow the instructions to complete the installation.

OS X will automatically continue installing onto the external hard drive rather than booting up to your internal version of OS X.

At the end of this article, I’ll show you how to boot up to the external hard drive, so skip down if you ended up using the App Store method. Note that by default, the Mac will start booting up directly to the external hard drive until you change it.
The second method to install OS X is to restart the Mac and press and hold the COMMAND + R keys. This will load up OS X Recovery.
The OS X Utilities screen will appear and here you want to click on Reinstall OS X. Again, you’ll go through some basic screens, but when you get to the hard disk screen, click on Show All Disks again.
Using this method, you’ll have to login using your Apple ID and password so that the entire OS X installer can be downloaded off of Apple’s servers. Whichever method you choose, it will take anywhere from 15 to 30+ minutes to install OS X onto your external hard drive.
While OS X is installing, your computer will restart a couple of times. Note that when it finally boots into OS X, that is the version running off your external drive. To switch back and forth between the internal and external drive, you have to restart your computer and hold down the OPTION key.
When you do that, you should see at least four icons. In my case, I have five because I have Windows installed using Boot Camp. Anyway, the grey MacBook and Recovery 10.11.2 icons are for my internal OS X and the orange OS X and Recovery 10.11.3 are for the version installed on my external drive.
