- Jul 22, 2019 Right-click your flash drive and then select Format. In the File System list box, choose exFAT, type in a Volume Label if you want, and then click Start. Click OK to the format warning and wait.
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 8: And then select a format that you want from the drop-down menu.
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 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.

How to format internal and/or external drive to work properly on Mac and Windows computers?
External data storage devices such as USB flash drives, external Hard Disk Drives (HDDs), and Solid State Drives (SSDs) provide one of the easiest ways to transfer files between separate computers without accessing the Internet. This option is often used when attempting to move very large files. The method is also chosen by people who work with media data that imposes various limitations and automatic optimizations when transferring via Internet. Despite the advantages of using external data storage to transfer content, some experienced users encounter problems caused by the difference between operating systems. This article addresses these issues.
A common issue discussed by users within various technical support forums is that of USB flash drives not working on their computers. This is a cross-platform problem that Windows and macOS users often experience. For example, a photographer may provide you with a USB flash drive with stored photos and videos from your birthday party, but you cannot access them on your system. This is the result of differences between operating systems on computers. Windows and macOS use separate file system formats. PCs with Windows operating systems use New Technology File System (NTFS) while Macs with macOS operating systems use Hierarchical File System (HFS+). By default, USB flash drives and external storage are formatted with the NTFS file system - this works flawlessly on PCs, while Mac computers are able to read data in the format, but struggle to write using this type of storage. Fortunately, there is a simple solution: format your external storage with the File Allocation Table (FAT32) or Extended File Allocation Table (exFAT) file system. In this article, we describe the differences between these two file systems and how to format external storage using a Mac computer.

Which file system to choose - FAT32 or exFAT?
As mentioned above, both file systems are compatible with Windows or macOS/OS X operating systems. Naturally, the question is: which should you choose? To make the choice easier, we describe both file systems and their features below.

Starting with FAT32 [on a Mac, known as MS-DOS (FAT)], this file system is fully compatible with all versions of Windows and Mac operating systems. Therefore, even the oldest versions of operating systems such as Windows XP SP1 and OS x 10.5 Leopard are compatible. As well as computers, the FAT32 file system is supported by PlayStation 3, Xbox 360, and most cameras. This particular file system does contain file size restrictions. For example, the maximum size of supported files is 4GB (you cannot write files larger than 4GB). Also, you cannot create a startup drive for Mac computers within storage media that uses the FAT32 file system. If, however, you are not planning to use external storage to transfer large files or create any executable partitions (such as a Mac startup drive) the FAT32 file system might be an option, since this format is supported in all versions of the operating system.
exFAT is a newer file system format and has the biggest advantage when compared with FAT32: there are no restrictions on file or partition sizes stored. Therefore, you can write a file of, for example, 1TB size and create partitions of 5TB within the device. Despite this improvement of available data size, some older versions of operating systems are no longer compatible with this file system format. The oldest versions of operating systems compatible with exFAT are listed below:
- Mac OS X Snow Leopard 10.6.5 or later
- OS X Lion
- Windows XP SP2 or later (with an additional update for exFAT support)
- Windows Vista SP1 or later
- Windows 7
Unfortunately, as well as some old versions of operating systems, the exFAT file system format is not supported by various cameras, video games consoles, and other devices able to read and/or write to external storage. If you will be using a USB flash drive or external storage device with any of these, the required format is FAT32. Otherwise, if the device is to be used only with computers with modern versions of operating systems, the recommended format is exFAT.
Format Usb Flash Drive For Mac And Windows
Format the drive with Mac computer
Firstly, bear in mind that formatting the drive will erase all content stored on it. Mac computers are capable of formatting any storage device (internal or external) such as HDD/SSD, USB flash drive, and external storage. Even if the Mac is unable to mount the storage, following this method will enable you to format the storage. Begin by connecting the storage device to your Mac, and then launch Disk Utility using Spotlight. Simply use the keyboard shortcut of Command and Spacebar, type Disk Utility, and then press return. Alternatively, open Finder and go to Applications, open Utilities, and then launch Disk Utility. Select the drive you wish to format from the list in the left sidebar of the Disk Utility window.

Then click the Erase button at the top of the window, in the new pop-up window, and type the name of drive. Then click the drop-down menu beside Format and select MS-DOS (FAT) - the FAT32 file format - or exFAT. These formats are described above.
If you are not planning to use this drive as the Windows startup disk or use it with the oldest version of the operating system, do not change the Scheme. Select Master Boot Record.
Finally, when all preferences are set, click the Erase button. The formatting process duration depends on size and type of the drive. A hard disk drive will take longer to format than a flash drive. NOTE: formatting will erase all existing data on the drive.
