For Apple Mac users, there are two ways to format USB flash drive to FAT32, including Disk Utility and Terminal command line. Refer to detailed steps of using both tools for FAT32 format. Formatting would erase data completely, make sure that you have a data backup. Otherwise, you can use data recovery software to recover data from a formatted USB drive.

Are you looking for a secure way to format USB to FAT32 on Mac? You are at the right place. Follow here, you can find two methods that will assist you in doing so on your storage device. And if you lost data during the formatting, reliable Mac file recovery software is ready to help anytime:

• The whole purpose of exFAT was to allow easy transfer of large files between platforms in a format that didn't require third party drivers on either the Mac or Windows to read the drive. To make sense of why MS would cut off the use of exFAT for internal hard drives, it has to be understood that exFAT still doesn't have a final specification.
• Thankfully, exFAT — a strict upgrade over FAT32, is a file system optimized for USB flash drives. Like I said, if you want to use the device for both a PC and Mac, you should consider reformatting it to exFAT once you figure out the drive isn’t with another file system.

Even after completely formatting all the files from an exFAT or FAT32 USB flash drive we can completely recover it or even we can repair the damaged data. Here we explain it in such a way that each one of you can format USB drive without losing data.

How to Format a USB Flash Drive with Mac to FAT32

Computer users who use a USB might have the demand for formatting it to the FAT32 file system. Compare with the other commonly used NTFS file system on a flash drive, FAT32 has a compatibility advantage across many operating systems.

It's a universal format that is compatible with Mac OS X/macOS, Windows, Linux, and DOS systems. So, if users anticipate using the flash drive with more than one operating system, they will definitely benefit from the FAT32 file system. For Apple Mac users, there are two ways to format a USB flash drive to FAT32, namely Disk Utility and Terminal command line. Below are the detailed steps of the FAT32 format with both methods.

Method 1. Format FAT32 on Mac [Disk Utility]

To format USB to FAT32 with Disk Utility will erase all data on the flash drive, so before you doing so, please do remember to check whether you have saved useful data to another secure device in advance.

To format the USB drive to FAT32, follow the next steps:

Step 1. Connect the USB flash drive to your Mac computer.

Step 2. Go to Applications >Utilities > Double click and open Disk Utility.

Step 3. Select your USB flash drive on the sidebar, choose Erase.

Step 4. Rename the USB flash drive (optional).

Step 5. Choose the format as MS-DOS (FAT) for Format, Master Boot Record for Scheme. Then click Erase.

Wait for the process to complete, then you'll get an empty new USB flash drive with FAT32 as the file system. You can use it for saving data again.

Method 2. Format FAT32 on Mac [Terminal Command Line]

The command-line behavior does the same way to erase data with the Disk Utility. Again, create a backup before taking this action.

To format FAT32 on Mac with Terminal, follow the next steps:

Step 1. Connect the USB flash drive to your Mac computer.

Step 2. Hit cmd + space to run Spotlight, type: terminal, and hit Enter.

Step 3. Type: diskutil list and find out which disk is your USB drive.

Step 4. Type: sudo diskutil eraseDisk FAT32 MBRFormat /dev/disk2.

• sudo gives you user right.
• Diskutil calls disk utility program.
• eraseDisk commands to format.
• FAT32 sets the file system.
• MBRFormat tells disk utility to format with a Master Boot Record.
• /dev/disk2 is the location of the USB drive.

Wait for the process to complete. After this, you can type 'diskutil list' in the command again to check if the formatting has been successful.

Bonus Tip: How to Recover Data from Formatted USB

Formatting the USB would erase the data on it completely, so please make sure that you have a backup. If you don't, you can count on data recovery software to retrieve the lost data.

EaseUS Data Recovery Wizard has both Windows and Mac versions, so it's a good choice for data recovery, no matter you're using a PC or Mac.

To guarantee an effective data recovery without spending money to no avail, you can install the Mac data recovery free version for the first trial. You can preview all the found data before the final recovery.

To recover data from a formatted USB flash drive on Mac, follow the next steps:

Step 1. Correctly connect your USB flash drive to your Mac. Launch EaseUS Data Recovery Wizard for Mac. Start selecting the flash drive and click 'Scan' to let the software search lost files on it.

Step 2. After a quick scan and deep scan, all files will be presented in the left panel in the scan results.

Step 3. Select files you want to recover and click the 'Recover Now' button. Don't save the recoverable files to the USB drive itself in case of data overwriting.

Most of the time formatting a flash drive is a very simple decision. There are only two situations where you should take consideration on what format to use. Here are the details:

Note: This article is focused towards Windows and Mac operating systems.

The file formats available for a flash drive are:

• FAT (also called FAT16)
• FAT32
• exFAT
• NTFS
• HFS (Mac only)

Flash drive manufacturers format a drive as either FAT or FAT32. Any device of 2GBs or smaller will be formatted as FAT and any USB over 2GBs will be formatted as FAT32.

These two formats are the best file system for removable drives like flash drives because they support the quick disconnect function and chances are very slim you will destroy the device or files if you unplug the USB without using the Eject function (in Windows) or Un-mount function (in Mac).

The one huge limitation with FAT and FAT32 is the single file size limitation. If a single file is larger than 2GBs you need to have the device as FAT32. If you have a single file bigger than 4GBs then you must use NTFS or exFAT. Typically these large files are either video files or restore image files (for restoring a computer operating system from a single image file).

So what if you have a file bigger than 4GBs? Well, you have to decide what is the lesser of two evils.

Here is the problem. If you format as NTFS it works great on all Windows machines, but Macs can only read from the device, they cannot write to it. There are some plugins to help the Mac deal with NTFS but our experience proves those add-ins to be unstable.

If you format it as exFAT all computers (Windows and Macs) will see the drive except for Windows XP.

So you must decide to accommodate the Windows XP users or accommodate the Mac users.

Given that Mac computers are on the rise, your best option is to format the drive as exFAT. If there is a Windows XP user out there, they can download the plugin from Microsoft to allow an XP operating system to see the exFAT device without wanting to format it. Also keep in mind that XP is a 15 year old operating system (at the time of this post) and Microsoft no longer supports the OS.

As a closing note, the NTFS file system is not ideal for flash drives because it’s a dynamic file system. Meaning information can be writing to the flash drive at times in which you think the USB is idle. So in a situation where you disconnect the USB while there is a write change taking place to the file system, there is a good chance you will corrupt the data. Not good.
