This simple guide will teach you How to Format a Flash Drive on Mac. Not only this, we will help you pick the best file system for your usb flash drive that you are planning to use on a Mac.
Majority of 49.4% of desktop and laptop computer users in the world use Windows operating system. In contrast, only 27.4% of users use MacOS, obviously for their apple computer. That’s the reason why most of the flash drives in the market are available in Fat32 or NTFS formats which are the most preferred format for windows. Although the first one, Fat32 is completely compatible with both MacOS as well as Windows, it has some limitations. Fat32 can store files only up to 4 GB of size. The latter one, NTFS is mostly used on the Windows operating system and not an optimal option for MacOS. Extra work is needed to use NTFS on MacOS. If you want to use your flash drive solely for MacOS, it is highly recommended to format your flash drive.

Before you format a flash drive
MacOS supports HFS plus file system. HFS stands for Hierarchical File System.
Apple introduced this file system in 1985 to replace the existing Macintosh File System or MFS. HFS filesystem is modified into HFS plus (Modernly called as MacOS Extended). Before you format a flash drive it is suggested to know what file system your flash drive is in.
Check flash Drive’s File System
You don’t need to do anything special to know your flash drive’s file system. There are 2 ways you can do this.
Method 1: Using Finder
Plug in your flash drive. Now open the Finder and look for your USB device. Then right-click on the drive’s name. Select “Get Info” from the list of options opened.
A new window will open. Just to the right of “Format” is your drive’s file system.
Method 2: Using Disk utility app
Open the Disk Utility app from the utility folder available in the application. Your drive will be on the left column of the window. Click on the partition. Here you can check the current format of your flash drive.
If your flash drive’s file system is MS-DOS or ExFAT you can use it as it is without further formatting. But if it is NTFS, format your flash drive to make it completely compatible with MacOS.

Disk Utility application in MacOS is the best option to format a flash drive on MacOS. You can launch this app in two ways.
Step 1: Press Space while holding your command button. A search box will open. Type Disk Utility in the search box and press enter. Alternatively, Open the Finder window and select applications on the left sidebar. Navigate to Utilities and then Disk Utilities.
Step 2: Search for your flash drive on the sidebar of the Disk Utility app and select it by clicking on its name.

Step 3: Now Click the “Erase” button which is located just below the title bar of the window which says “Disk Utility”. This will erase your whole drive and make it a single partition.
Here you can change the name of your USB drive if you wish. This name will be visible on other devices as well if you plug your flash drive into them. Just below the Name section, you can see a section called “Format”.
You will need to choose a format option to change your flash drive’s file system. But which format to choose is the big question now! No need to worry. Read the description of each format given below and choose the format of your choice.
Types of filesystems
Mac OS Extended (Journaled)
Flash Drives For Macbook
This format is considered as default file system format of the Mac OS X drives. It also supports OS X Lion, like Versions. This format will allow you to use your flash drive on Mac without any limitations.
With Mac OS Extended (Journaled) format, you can setup OS X startup drive. Make sure you have right files and know how to do it. If you have any issues with a built-in drive you can boot from the external disk. This file system format is highly recommended for MacOS. But you cannot write this flash drive from windows PC once you have formatted it as Mac OS Extended (Journaled). You can read files though.
Macos Flash Player
OS X Extended (Case-sensitive, Journaled)
Go for this type of filesystem if you really need it for some reason. For OS X Extended (Case-sensitive, Journaled), the word “File” is different than “file”. It means it’s case sensitive as the name suggests.
OS X Extended (Case-sensitive, Journaled, Encrypted)
Same as filesystem just mentioned above but of course with encryption.
OS X Extended (Journaled, Encrypted)
To use a flash drive with this filesystem you will have to set up a password & enter it whenever you plug in your drive into any device.
MS-DOS (FAT)
This is just a name for the FAT32 filesystem in Disk Utility application. FAT32 supports to almost all of the operating systems in the world. This allows you to transfer files from one operating system to other. The best thing about this filesystem is its support to video game systems which include Xbox 360 and PlayStation. This filesystem can be called a universal system. The limitation about FAT32 filesystem is it doesn’t allow files which are bigger than 4 GB in size and also you cannot create a startup drive unlike Mac OS Extended (Journaled).
Flash Drives For Macos Windows 10
ExFAT
This is a new type of filesystem and it supports MacOS X 10.6.5 and later. It is same as FAT32 but it supports files larger than 4 GB. As this filesystem is relatively new, it does not on relatively older versions of Mac OS X. If you don’t use any older version of the operating system, you can use this type of filesystem.
Use ExFAT for this tutorial if you wish to use your flash drive on windows as well on MacOS.
Step 4: For this tutorial, you can ignore the Scheme option which we use if you wish to boot from your flash drive. Click on erase button to format your flash drive.
Voila! You have formatted your flash drive now. You can eject drive by right-clicking on its name in the left sidebar and click on “Eject”.

On Windows 10, the ability to format a USB flash drive can come in handy in a number of scenarios. For example, you might want to reformat a new or used removable storage device to make sure it doesn't contain any malicious code. Or if a thumb drive is inaccessible because of data corruption. Maybe you received a flash drive using a file system that isn't compatible with your system configuration. Or you're planning to give the drive away and want to make sure personal information doesn't go along with it.
Whatever the reason, Windows 10 ships with several tools to format virtually any kind of storage, including USB flash drives, using File Explorer, Disk Management, Command Prompt, and PowerShell.
In this Windows 10 guide, we walk you through the different ways you can format a USB flash drive to quickly erase its contents or fix problems when the device isn't recognized.
Warning: Using any of the instructions outlined below will erase the contents on the drive you select. If you have any important files, you should back them up before proceeding.
How to format a USB flash drive using File Explorer
To format a USB flash drive using File Explorer, use these steps:
- Open File Explorer.
- Click on This PC from the left pane.
- Under the 'Devices and drivers' section, right-click the flash drive and select the Format option.
- Use the 'File system' drop-down menu and select the NTFS option.Quick tip: If you're planning to use the removable drive on Windows 10 as well as on macOS systems, you may want to select the exFAT option for compatibility. However, if you're also thinking about using the device on a Linux machine, FAT32 is the best option, even though you'll be limited to 4GB file sizes.
- In the 'Allocation unit size' drop-down menu use the default selection.
- In the 'Volume label' field, type a label to quickly identify the flash drive in File Explorer. For example, workFlash.
- Under the 'Format options' section, select the Quick format option.Note: The 'Quick format' option only deletes the file system table and the root folder, but the data may still be recoverable on the drive. If you don't check the option, a full format will take place, and it'll perform a scan for bad sectors and writes zeros in all sectors to delete the data. As a result, the process can take a long time depending on the size of the storage.
- Click the Start button.
- Click the Yes button.
Once you complete these steps, you can start storing documents, pictures, videos, and other files on the removable drive.
How to format a USB flash drive using Disk Management
