Are you having trouble creating Mac OS Extended (Journaled) and APFS partitions using Disk Utility? If so, you can create a Mac OS Extended partition using GParted, then convert to APFS using Disk Utility.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.
- Run GParted and select the hard disk in the dropdown list at the top right. My hard disk is /dev/sda.
- 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.
- Select hfs+ in the File system. Then select and enter some information for the other items you want.
- 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!

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 formats. 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 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 the 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 that 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.

- The 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 if 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 that is capable of recovering all kinds of files with wide format support of 1000+.

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.

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 that 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.
Format Flash Drive To Mac Os Extended On Windows
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, you must 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 an 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 the original condition.
