In today’s technology, if you buy a USB hard drive, you can just simply use it directly using your Mac. However, there are instances that not unless that your flash drive is build to use for your Mac, you will not be able to format it.
Why is this so? The answer to this is because most of the computers actually run on Windows and they actually use a different file format which is known to be the Fat32.
Those drives that are formatted in Fat32 can be used in your Mac for reading and writing but there might be an instance that you might experience some trouble once that you use your macOS native format.
So, in case that you have a flash drive that is formatted into Fat32 or any type of format rather than having a Mac OS Extended or AFPS, then we are going to show you in this article how you could possibly format your flash drive using your Mac.
Part 1: How To Format Flash Drive On Mac
Here are the steps that you need to follow. Do these steps and you will then be able to format your flash drive on your Mac.
Step 1: Go ahead and plug in your flash drive in the USB port on your Mac.
Step 2: After that, go ahead and launch the Finder and click on your flash drive detected by your Mac.
Step 3: See to it that there are no files saved on your flash drive that you no longer need. This is because formatting your flash drive will remove all the data that is stored in it. If there are some files that you want to remain, simply copy these files to your Mac.
Step 4: After getting all the files that you need from your flash drive, go ahead and click on “Applications” and then click “Utilities” and then choose “Disk Utility”.
Step 5: And then, go ahead and click on your flash drive from the sidebar.
Step 6: Once that you have chosen your flash drive, go ahead and click on the “Erase” button located at the toolbar at the top of the window.
Step 7: On the next window that will appear on your screen, go ahead and key in a name for the flash drive that you are formatting from the box next to the “Name” option.

Step 9: No, if you have previously stored a data on your flash drive that is highly sensitive, just go ahead and click on the Security Tab.
Step 10: From the security tab, go ahead and choose the level of the security that you want. The more that you move to your right, then the more “passes” the deleted tool will be but it will securely delete your files. However, doing to so will take more of your time to format your flash drive.
Step 11: After that, go ahead and click on the “OK” button and then click on the “Erase” button.
Part 2: Choosing the Right Format
There are formats that you need to choose from depending on the Mac that you are using. If you are using the macOS Sierra or a later version, then you have to options to choose from. One is the AFPS and the other one is the Mac OS Extended. The question now here is that which one should you choose.
You have to keep in mind that once you have formatted your flash drive into AFPS, then those Macs that are running on macOS that is older than the High Sierra will not be able to recognize it.
So, if you would want to use your flash drive on Macs that are running on High Sierra, then you have to choose the Mac OS Extended format.
However, you also have to know that AFPS is actually optimized for SSD or “solid state drive” and it includes flash drives.
That is why if you are going to reformat a flash drive on your Mac, then you should definitely choose the AFPS format as it is known to be the most reliable and faster than the Mac OS Extended. But again, that is if you do not have any plans in using it on a pre-High Sierra course.
And lastly, if in case that you would want to use your flash drive as one of your backup options in Time Machine, then you should definitely have it formatted in Mac OS Extended.
This is because Time Machine does not have the ability yet to backup flash drives that are formatted in AFPS. So, if you are using an AFPS formatted flash drive on Time Machine, it will just ask you to format your flash drive into Mac OS Extended.
Part 3: How To Format Flash Drive To Fat32 On Your Mac
Once that you have a flash drive, then what you would need to do is to have it formatted into Fat32. Why? This is because once that you have formatted your flash drive into Fat32, then you will be able to use it on both Windows and Mac PC when you want to save or transfer files with either of the two.
The Fat32 format can be used – read or write – with both Mac and Windows PC and because of this, it makes the device more versatile.
However, there are some limitations that you should need to know such as an individual file should only have a maximum size of 4GB. But do not worry because there is still something you can do about it and that is by formatting it to exFAT.
The exFAT format will not give any limitations on the file size that you are going to store on your flash drive and you can still use it on both Windows and Macs that are running in Mac OS X Snow Leopard or later version. For you to be able to format your flash drive into Fat32, here is what you need to do.
Step 1: Go ahead and connect your flash drive to your Mac.
Step 2: And then, go to Application and then click on Utilities.
Step 3: After that, go ahead and launch Disk Utility.
Step 4: And then, go ahead and click on your flash drive located at the sidebar in Disk Utility.
Step 5: After that, click on 'Erase' in the Disk Utility window.
Step 6: After that, go ahead and enter the name for the flash drive that you formatted.
Step 7: And then, choose the Format menu and then select MS-DOS (FAT32) or the ExFAT.
Step 8: After that, go ahead and click on the 'Erase' button.
Once that you are done with the provided steps for you, your flash drive will then completely wipe out all the data stored and it is re-formatted into either an ExFAT or FAT32 depending on what you have chosen on the previous steps.

Common File Systems for Mac and PC
The file system is one of the most important part for an external hard drive because it manages how your files are stored and retrieved. So, every hard disk needs a proper file system, including desktop drives and portable storage devices like external hard drives, USB flash drives and SD cards. However, different file systems have different advantages and disadvantages. So before you know how to format a hard drive, you should know the pros and cons of each file system.
1. FAT32
FAT file system includes three major file system variants but the majorly used one is FAT32. FAT32 is commonly used in floppy disks, SD memory cards, USB flash drives, digital cameras, as well as many portable and embedded devices.
Pros
- Works universally with all versions of Mac, Windows, Linux, game devices, as well as other devices supporting a USB port.
Cons
- Doesn't support a file size larger than 4GB and a drive partition size larger than 32GB on Windows.
- Doesn't support the drive partition larger than 2TB on macOS.
2. exFAT
exFAT is a good option for external hard drives (e.g. Seagate Backup Plus Slim), especially for large-capacity removable storage devices. It also is frequently used in flash memory drives such as USB flash drives and SD cards. exFAT is easily often implemented in firmware that has low memory and low power requirements, such as cameras, mobile phones, media players, etc.
Pros
- Supports the largest partition and file sizes by today's standards.
Cons
- Not compatible with too much old operating systems.
- Not a good option for drives less than 32GB because it can't maximize space utilization.
3. NTFS
NTFS is a proprietary journaling file system developed by Microsoft. It is used as the default file system of Windows system hard drive (e.g. Windows 10). NTFS does well in data security based on its encryption, access permission control, and log file.
Pros
Using Flash Drive On Mac
- Improved performance, reliability, and disk space use.
- Performs better in protecting data security, data management.
- Compatible with all versions of Windows and latest hardware.
Cons
- Read-only in macOS and the disabled-by-default write support for NTFS in macOS is unstable.
4. Mac OS Extended (HFS+)
HFS Plus or HFS+ is a journaling file system developed by Apple Inc. It's the startup disk’s default file system before macOS High Sierra. It also frequently used as Time Machine backup external hard drives of WD, Seagate, etc.
Pros
- Supported by all versions of Mac OS X and macOS.
- Has journaling, compression, and encryption features.
Cons
- Has no access permission control.
- Perfoms slow or crash in dealing with a large number of files.
- Harder for data recovery when an HFS+ hard drive is corrupted.
5. Apple file system (APFS)
APFS is the new proprietary file system of Apple. It has been known to increase read/write speeds on solid-state drives (SSDs), as well as increase storage space due to the way in which it calculates the available data on disk.
Pros
- Allows full-disk encryption with single or multi-key encryption for added security.
- Efficient in management of free storage space
Cons
- Not good for Time Machine backup due to no support for hard links to directories.
- Can only be used on macOS 10.13 and above.

Out of the box, Windows can't read or write to HFS+/APFS drives and Macs can't write to NTFS drives either.
Sometimes, users need to use the same external hard drive interchangeably on Mac and PC. To make it compatible with both macOS and Windows, you need to reformat the external hard drive.
Whether you are using an APFS/HFS+ or a Windows NTFS formatted external hard drive on Mac, you can reformat the external hard drives for both Mac and PC. File systems like FAT32 and exFAT can make the external HDD compatible with both Macs and Windows PCs.
Warning: Reformatting will wipe files off the external hard drive. So, you should make sure you have backed up your files on the external hard drive before you continue any steps.
When should you choose FAT32 file system?

So, If all your files on the external hard drive are smaller than 4 GB, and the drive itself is smaller than 2 TB, then FAT32 is a better choice for you to use the hard drive on Mac and PC.
When should you choose exFAT file system?
Similarly, exFAT is also a widely compatible file system. The difference is that exFAT has no limitations on file size and hard drive size. So, when the external HDD you want to used for both Mac and PC is larger than 2 TB, exFAT is the best choice.

What to do if you can’t format the external hard drive on Mac?
Usually, to format the external hard drive as FAT32 or exFAT, you are advised to do this on a Mac computer via Disk Utility. But if you have formatted the external hard drive under the Windows system, it would cause some inconvenience. You can't add or re-partition volumes of the external hard drive again on Mac. In this case, your only choice is to backup your files and reformat the whole disk.
How to partition an external hard drive for Mac and Windows PC?
Except for having the whole external hard drive formatted, you can also split this disk with two partitions. One is formatted with the file system that is compatible with macOS, another partition is compatible with Windows conversely. By this means, you can use all the advantages each format has on the respective system.
Warning: Still, you need to back up files on this drive before you begin to create two separate partitions to work for Mac and Windows PC.
For some Mac models, the partition option would be greyed out in Disk Utility. So, we suggest that it's better to use a PC to partition an external hard drive for macOS and Windows. Here are the steps to partition an external hard drive for Mac and Windows PC, which is a little tricky.
Step 1: Connect the external hard drive to your PC and then launch Disk Management.
Step 2: Check if the external hard drive is initialized or not.
If the drive is not initialized, you need to initialize the external hard drive with Master Boot Record (MBR). Then you can create two new partitions. You need to format one of them as NTFS for Windows use and format the other as your wish.
If the external hard drive is initialized, you need to right-click the disk to check if it's an MBR external hard drive.
- If you see Convert to GPT Disk in the context menu, be it greyed out or lighted, it’s an MBR hard drive. Then you can create two or more partitions. And you need to prepare one partition for NTFS file system, and reformat with any file system.
- If you see Convert to MBR Disk in the menu, it's an GPT hard drive. In this case, you need first backup files, delete the existing partitions, then click the Convert to MBR Disk button. Then, you can create two new partitions. You need to format one partition as NTFS for Windows use, and then format the other randomly.
How To Format Flash Drive For Both Mac And Pc
Step 3: Up to now, there should be at least two partitions on the external hard drive. And one of them (the NTFS one) is ready for Windows use. Then, you need to safely remove the external hard drive and plug it into a Mac.
Step 4: Open Disk Utility and select the other partition (not the NTFS one) under the name of your external hard drive.
Step 5: Click Erase on the top, choose Mac OS Extended format when it asks, and chose Erase to finish.
Up to now, the external hard drive will have two partitions. One is HFS+ formatted for Mac, and the other is NTFS formatted for Windows.
By creating two separate partitions, you can use this external hard drive on both Mac and Windows. You won't be able to write to the Mac partition from your Windows computer, and vice versa. Thus, it's a good solution for people who need to swap between two operating systems but with separate work.
Make external hard drives compatible with Mac and PC without formatting
Many famous external hard drives like Seagate Backup Plus Ultra Touch and WD My Passport are pre-formatted with NTFS. However, the NTFS file system is a hassle for users who need to use the same external hard drive on both Mac and Windows. The external hard drive is not letting you add files if you use an NTFS external HDD on Mac. It will be read-only and you can't write to this drive normally in this case.
Many users don't know this and use the external hard drive directly. And when they want to reformat the hard drive to use it interchangeably, only to find that files on the drive are erased as well.
Then, can you solve external hard drive read-only without formatting?
