“I just bought a new USB flash drive and a hard drive for extra storage, but they are not compatible with my Mac. The only solution I can find is to format the drives but I don’t know how. Can someone tell me how do I format a new hard drive for Mac?”
There are lots of people who mistakenly think that the USB drives and hard drives format don’t really matter. But the reality is quite different. Whether it is a hard drive or USB or internal drive, Mac uses different format support. So, you can’t simply use the same drive with both Windows and Mac. As a result, you will need to format the hard drive for Mac. Using the Mac preferred file system is important otherwise the files will be of no use to you.
Mac OS X can only be installed on a hard drive formatted in Mac OS Extended ( Journaled), filesystem. So if you wish to clean a hard drive for a fresh install of OS X you will need to format it under Mac OS Extended ( Journaled). If you want to create an encrypted drive for Mac, it should be formatted in Mac OS Extended (Journaled).
In this article, we are going to discuss how to format a hard drive for Mac and some related terms too.
- In the Volume Format drop-down menu, select Mac OS Extended (Journaled) if you plan to place the Mac Tiger operating system on this drive to make it a bootable drive. Select Mac OS Extended if you plan to use the drive as a media (capture scratch) drive. Name the drive. Install Mac OS 9 Disk Driver.
- 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).
- With the release of the Mac OS X 10.2.2 update on November 11, 2002, Apple added optional journaling features to HFS Plus for improved data reliability. The formatting decides the way the files are stored on your hard disk. Mac OS Extended (Journaled) is the normal recomended way to format your drives, internal and external.
May 21, 2020 However, when we connect a NTFS formatted disk to Mac, Mac OS X doesn't allow us to write files to the drive neither edit files, though it can read a NTFS drive. Similarly, Windows OS will ask us to format the HFS+ formatted drive when we connecting such a disk, let along edit files saved on HFS+ formatted hard disks unless we resort to third. Apr 01, 2020 If you can’t decide between APFS vs Mac OS Extended for your drive, you should consider your use case first. The newer APFS format is better for some types of drives, including SSDs, while Mac OS Extended is great for older drives and macOS versions. Here’s a run-through of the pros and cons of both to help you decide.
Part 1. Situations When Formatting a Hard Drive on Mac:
Before you get deep, it is important that you understand what is drive formatting. Some people confuse the term with reformatting. Basically, formatting is the process of preparing the storage devices such as hard disk drive, solid-state drive, USB flash drive, or any other for initial use.
The basic operation is termed as low-level formatting which means erasing the existing data on the disk. But it leaves the track to recover the data using the recovery tool.
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. It is usually done during the OS installation or adding a new disk. Reformatting is done to free the storage space from the previous content stored in it.
You can consider disk formatting in macOS in the various circumstances. Whether your system has corrupted data, damaged software, impending system upgrade, storage is full, or it is running slow, formatting will fix a lot of issues. Take a look at the scenarios given below and you will be sure that disk formatting will help you.
- If you want to quickly erase all content from the drive permanently without leaving a trace of data on it.
- If you want to change the format of the disk such as PC format like FAT or exFAT to Mac format.
- If you see the message that the disk is not readable by Mac.
- If you want to resolve a disk issue that can’t be fixed by Repair feature of Disk Utility.
- If the macOS installer can’t see the disk or unable to install it.
- In case the macOS installer says that the drive can’t be installed because it is a part of Apple RAID.
Under all these situations, formatting is most likely to fix your problems and you will be able to use the drive on Mac.
Part 2. How to Format a Hard Drive on Mac:
Formatting is a very simple procedure which is operated in a similar way for all sorts of storage media. So, whether you wish to format the internal hard drive, external drive, or a USB flash drive, the procedure is the same for all. Here is the step by step guide you need to follow to format the hard disk on Mac. Before you erase a disk, make sure that you have a backup of the files you want to keep.

![Drive Drive](/uploads/1/2/6/4/126455964/883313776.png)
Step 1: Connect the USB drive or external drive to Mac and launch the Disk Utility from Applications.
Step 2: From the left side panel, pick the volume or the drive that you want to format and switch to the Erase tab.
Step 3: As you click on the Erase button, you will see several fields in the section. Enter the given information-
- Name- Enter a name for the disk such as Macintosh HD/SSD/USB Drive or anything else you want.
- Format- You have to choose a Mac supported format from the list. The most recommended format is APFS or Mac OS Extended (Journaled). There are numerous other formats too which will be displayed in the drop-down menu. You can select any format as per your requirement.
- Scheme- If this option is available, then you should choose the GUID Partition Map from the option.
Step 4: After specifying the fields, click on the Erase button at the bottom of the window and Disk Utility will format the drive.
Once the formatting is complete, you can use the disk for a backup drive, sharing, time machine backup, or any other requirement. In case the drive doesn’t appear in the Disk Utility interface, you will have to disconnect all the extra and non-essential devices connected to Mac. Make sure that the External drive is on and connected properly. Restart your Mac and then carry out the task.
Part 3. How to Perform Mac Data Recovery After Format:
There are situations when Mac users don’t get the chance to create a backup of their data and forced to format the hard drive. But you don’t need to panic. You can get your hands on Recoverit data recovery for Mac. If you have mistakenly formatted the data that you still need, Recoverit is the best chance you have to get the files back. It is a complete data recovery solution which is capable of recovering all kinds of files with wide format support of 1000+.
You can download the software from the official website and install it immediately on Mac. Once the setup is complete, follow the steps below to recover formatted drive files.
Step 1: Specify Location:
Run the program and specify a location from the main drive. If data is lost from an external drive or USB flash drive, then you’ll have to connect the drive with the system and then specify the location.
Click on the Start button to initiate the scanning process.
Step 2: Scan Results:
Depending on the data that is lost or deleted, scanning will take some time. As the process finishes, the files will be displayed on the screen according to their respective format.
You can decide whether you want to look for files according to file type or file path. You can also stop the scanning process in between if the results are displayed before the scanning finishes.
Step 3: Preview and Recover Formatted Data:
As soon as the data is displayed on the screen, you can have a preview of the files. Select as many files as you want and have a preview of the files. Tap on the Recover button to save the files on your system.
As you are retrieving the files, keep in mind not to save the files in the previous location. Depending on the amount of recovery, it will take a while and ultimately you’ll have your files back. If the normal scan doesn’t work for you, Recoverit also has a Deep scan mode to look deeper for the deleted and lost files.
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.
Wrapping It Up:
As you can see, now you know how to format hard drive/ USB flash drive/ internal drive/external drive on Mac. So, from now on whenever someone is in need, you can help them. And formatting doesn’t always finish without complications. So, if you lost some important files while formatting the drive, you can use Recoverit data recovery software for Mac to restore them in original condition. Recommend the software to your friends and family and let them know that there is a master tool for recovery for both Mac and Windows OS in the market.

The Apple File System (APFS) is the file system used with Mac devices running macOS 10.13 High Sierra and later, while the older Mac OS Extended file system is available for older versions of macOS. You can still use either file system for your hard drives and attached storage devices, with both having their own pros and cons.
If you can’t decide between APFS vs Mac OS Extended for your drive, you should consider your use case first. The newer APFS format is better for some types of drives, including SSDs, while Mac OS Extended is great for older drives and macOS versions. Here’s a run-through of the pros and cons of both to help you decide.
When to Use the Apple File System (APFS)
Most users aren’t interested in the type of file system their drive uses—they just expect it to work. That’s exactly what you get with the now-default Apple File System (APFS) that Mac devices have been using since macOS 10.13 High Sierra was launched in 2017. It’s also used with other Apple operating systems including iOS.
APFS offers a number of speed and optimization improvements compared to HFS+, as well as improvements to data handling. For example, file corruption is significantly reduced compared to Mac OS Extended.
You’ll also notice that copying and pasting files on an APFS drive works almost instantly, thanks to improvements in the way macOS handles file metadata with APFS drives compared to the older HFS+.
The biggest downside to using APFS is that Macs with older macOS versions (macOS 10.12.6 Sierra and older) can’t read, write, or otherwise access drives that use it. If you have an older Mac, you’ll need to keep using Mac OS Extended or use an alternative like ExFAT instead.
If you back up your Mac using Time Machine, you won’t be able to use APFS, either. macOS continues to use the HFS+ file system for Time Machine drives for the time being. If you attempt to use an APFS-formatted drive, macOS will want to format it to HFS+ before you can proceed.
Along with APFS and Mac OS Extended (also called HFS+), you also have other file systems that can be used for external drives, including cross-platform options like ExFAT. For most users, however, APFS is the only file system they’ll need or want to use—but only if they’re (only) using modern Mac devices.
Choosing Mac OS Extended (HFS+) for Hard Drives
While Mac OS Extended (HFS+) is no longer the default file system for macOS installations, it hasn’t been completely abandoned by Apple, and it’s still a useful option for macOS users under certain conditions.
As we’ve mentioned, HFS+ is the default file system of choice for macOS Time Machine backup drives. You’ll need to use HFS+ if you plan on formatting a second hard drive or portable flash drive for use as a Time Machine backup—APFS drives won’t work.
You’ll also need to consider Mac OS Extended if you’re using older and newer Macs together, as older versions of macOS won’t support APFS. Other than functionality, however, there are still a few legitimate reasons why you’d choose HFS+ over APFS—the biggest reason depends on the type of drive you use.
Many of the speed and performance enhancements that APFS brings rely on using a high-speed SSD or portable flash memory drive. If you’re using an older, mechanical drive with a disk platter, those enhancements may seem largely minimal or non-existent.
With that in mind, and for cross-compatibility, you may decide to use HFS+ over APFS. You can format a drive with HFS+ using the macOS Disk Utility app, which you can launch from the Launchpad (Other > Disk Utility).
Using ExFAT on macOS and Windows
While you can only use an Apple file system like APFS and Mac OS Extended for your main system drive, another file system is also worth considering for external drives—ExFAT.
ExFAT is an older file system from Microsoft, intended as a replacement for the even older FAT32 file system used with Windows system drives before the switch to NTFS in Window XP. It removes the 4GB file size limit and the 2TB partition size limit of FAT32 drives and is generally considered a better alternative for flash storage.
If you’re thinking about using ExFAT, you’ll likely have a single objective in mind—sharing files across platforms. ExFAT should only really be used for drives that you plan on using with both macOS and Windows devices, as it’s the only file system that both operating systems support natively.
It is possible for Windows to read APFS and HFS+ drives, but it requires external software to do so. Likewise, macOS can read newer Windows NTFS drives, but not write to them.
For owners with Windows and macOS devices, using ExFAT for an external drive is a good option but there are alternatives, such as setting up your own cloud storage or sharing files between your devices over your local network instead.
APFS vs Mac OS Extended: Which Is Best?
There’s no winner in the APFS vs Mac OS Extended battle, as it depends on the drive you’re using. Newer macOS installations should use APFS by default, and if you’re formatting an external drive, APFS is the faster and better option for most users.
Mac OS Extended (or HFS+) is still a good option for older drives, but only if you plan on using it with a Mac or for Time Machine backups. If you need a cross-platform option, consider using ExFAT for your drive instead—both Windows and macOS can read these drives without any additional software.
