Part 2: Which Format to Choose When Formatting?

This is one of the most overlooked parts of the whole process. Many users do not know the importance of the file system when it comes to storage devices. Everything would be simple if every operating system in the world accepted all file systems. Then you would be able just to use any file system and call it a day. However, that is not the case.

A file system is like a set of rules that determine how data must be written to the storage device. There are mainly five types of file systems available that are in everyday use.

FAT32: A file system that has been in business since the early 1980s. They were once the goto file system for formatting windows based devices.

NTFS: NTFS or New Technology File System is the current standard in windows machines. It is the recommended file format for Windows computers. However, they are not suited for Mac OS.

ExFAT: A modified version of FAT32, which is capable of support higher data transfer bandwidths. They are readable by both Windows and Mac devices.

HFS+: Introduced in 1998 for Mac systems. It was the most common Mac file format until 2017. HFS+ is not readable by Windows machines.

APFS: This is the latest file format system used by Apple devices. When compared with HFS+, APFS is made for solid-state storage devices. APFS is only readable by Mac devices.

Now, when you are formatting a USB drive on Mac, you have an essential decision to make whether the USB should be readable by windows machines and Mac machines or just by Mac and not readable in windows.

If you want the USB device to be readable by both Mac and Windows devices, then you have three options – NTFS, FAT, or ExFAT. The macOS can read the NTFS files, but you cannot write anything to the storage device. With ExFAT, you can write and read on both MAC and Windows PCs and is our recommended option for an ultra-portable USB device.

If you want the storage device to only show up on Mac systems, then format your storage device with APFS.

Part 3: How to Format a USB Drive to FAT32 on Mac

i. Disk Utility

Step 1 Connect your USB flash drive to the Mac computer. Go to the Disk Utility and open it.

Step 2 Select the USB drive and click on the Erase option.

Step 3 You can type the formatted disk name and choose MS-DOS (FAT32) or ExFAT on the format menu.

Step 4 Click Erase, and the operation might take some time depends on the USB drive size.

Now we are ready to use the USB Flash Drive on Windows and Mac

ii. Terminal Command Line

The terminal command line in Mac can be used to format USB devices. This method can be used when you are unable to format the USB device through Disk Utility. As always, having a backup option will save you when plan A fails for some reason.

Let us go through the exact steps in formatting your USB drive to FAT32 on Mac using the command line. Make sure that you enter the commands in the right syntax. Follow the guide given below for more info.

Step 1 Connect the USB device to the Mac. Ensure that the computer has read the device.

Step 2 Press Command and Spacebar simultaneously. Type in "Terminal" and press enter.

Step 3 Type in the command diskutil list and this will display all the connected storage devices to your Mac.

Step 4 Now type in sudo diskutil eraseDisk FAT32 MBRFormat /dev/disk2, and your USB device will be formatted to the FAT32 file system.

The command eraseDisk is used to delete the data in your USB device completely. It is an essential step before formatting and cannot be avoided. Other supported file formats can replace the FAT32 file format. After the format process is over, you will see that that file format has now been changed to the FAT32.
