To format a drive on a Mac, you’ll need the built-in Disk Utility application. Press Command+Space to open the Spotlight search dialog, type “Disk Utility”, and press “Enter” to launch the app. You can also open a Finder window, select “Applications” in the sidebar, and head to Utilities Disk Utility.

You can format the external hard drive or USB drive to make it compatible with both Mac and Windows machines. This thing is still unknown for many users but doesn’t worry it’s not complex.

If you are tech savvy and use Windows and Mac computers frequently, then you might need to transfer data between Mac and PC. Windows and macOS filesystems are different and you might need to format the drive every time to use on both platforms. You don’t need to format the hard drive every time you can choose a filesystem while formatting the drive so the hard drive or USB drive work on both Mac and PC

So to get rid of these situations we bring here a guide that will help you to format your drive which works on both platforms and you don’t need to format and backup data every time. After cross-compatible formatting, simply unplug the drive from one machine and then plug it into another. Sounds good to you right? So let’s started, how this works.

1. To format your USB drive on Mac, enter the following command: sudo diskutil eraseDisk FORMAT VOLUME-NAME USB-LOCATION-AND-NAME Where: FORMAT is where you choose which format you want to use when erasing and formatting your pen drive. There are many file types available when you format a USB drive on Mac, such as exFAT, FAT32, JHFS+, etc.
2. Please follow this procedure to format a large drive greater than 32GB with a FAT32 file system using Seagate DiscWizard: Reformatting the drive will erase all data on the drive, so you should copy any data you want off the drive prior to formatting. Install and launch DiscWizard 1) From the DiscWizard home screen, select Tools then Add New Disk.

Understand file systems for Mac and Windows

There are three common file system types to format an external USB or hard drive, SSD drive, SD card and etc. FAT32, NTFS, and exFAT let’s have a look what’s the difference between these formats.

FAT 32 Format

This format is pretty old but supported and it’s not efficient as compared to NTFS. It doesn’t support big features but offers great compatibility which means it’s compatible with all versions of Windows. It can only support 4GB file size and up to 8TB hard drivers. It’s not capable to store files larger than 4GB.

NTFS Format

NTFS is a modern format system and Windows also uses this format for itself and for other non-removable drives by default. This format is also compatible with all versions of Windows but limited to none Windows OS as FAT32.

exFAT Format

exFAT drives are faster at reading and writing as compared to FAT32. This format can store large files and it’s also lightweight. It’s compatible with all versions of Windows and the best thing it’s along with Windows it’s also compatible with macOS, Linux, and Android, etc.

• If your drive is formatted as Windows default format NTFS then it’s only readable to macOS. You can’t do more than that or you have to install a separate app on Mac to read write the drive.
• Drive with macOS format HFS+ cant readable to Windows.
• FAT32 format works on both Windows and Mac but the problem is you can only work with files with a maximum size of 4GB.

FAT32 is much better than NTFS and HFS+ becuase it works on both operating systems. You can also install drivers on each OS to make work your drive. So exFAT is much better than all of these formats and a simple option but this will not work on Leopard.

Format a USB Drive on Mac

Time needed: 5 minutes.

First, let’s see how to format an external hard drive or USB drive in macOS which works with both Mac and PC platforms, first plug-in your drive into a macOS machine.

1. Disk Utility

   Open Disk Utility on your macOS, press cmd + spacebar keys, and type Disk Utility in the spotlight search. Open Disk Utility from the search results.

2. Erase Drive

   On the Disk Utility interface, select an external drive click on the Erase button from the top of the window (make sure and backup your drive before erasing it).

3. Drive format

   Now enter the name for the external drive which will be used after formatting and also select the exFAT for Format option and click on the Erase. This will format the drive as exFAT format and your drive is now compatible with both platforms.

Format USB Drive in Windows

The below steps for formatting external drive is for Windows 10 and also works the same with an old version of Windows. To format your external drive hard drive in Windows to use on Mac and PC platforms, first plug-in your drive with a Windows machine.

Open the Disk Management tool by right-clicking on the start menu icon and then select Disk Management. Now right click on the external drive and click on the format option (double-check the drive name and capacity to make sure you are going to format the right drive.)

Now enter the Volume label as you need and change the File system for exFat and click OK. Now you are done.

Share your experience, how do you use an external hard drive on both Mac and PC. Did you format the drive as exFAT ? or use any utility that helps the system to read another type of file system. Please leave a comment below.

If you need to format a USB flash drive, HDD, SDD, or some other form of storage to FAT32, you've come to the right place.

In this article we'll go over what a file system is, the FAT32 standard, and several ways to format a storage device to FAT32 on Windows 10.

What's a file system?

A file system is a standardized way of organizing data on a computer storage device like a flash drive or HDD.

A file system divides a storage device into virtual compartments, almost like a wall of post office boxes, and keeps track of all the information that gets stored in each box.

Some of the most common file system formats for portable storage devices are FAT32, NTFS, and ExFAT.

FAT32 compared to other formats

Of those three common formats, FAT32 is the oldest and most widely supported. Every major operating system will allow you to read and write from a USB flash drive that's formatted to FAT32.

Meanwhile, macOS can only read NTFS drives, and you would need to install third-party software to write back to the drive.

However, though FAT32 is well supported, its maximum drive and file size is severely limited when compared to newer formats like NTFS and ExFAT:

Max drive size	Max file size	Windows	macOS	Linux
FAT32	32 GB (Windows), up to 16TB (Other OSs)	4 GB	Read/Write	Read/Write	Read/Write
NTFS	8 PB*	16 EB**	Read/Write	Read	Read/Write
ExFAT	128 PB*	16 EB**	Read/Write	Read/Write	Read/Write

* 1 petabyte is about 1 thousand terabytes
** 1 exabyte is about 1 million terabytes

Note that the maximum drive and file size of NTFS and ExFAT is so large that there's basically no limit. (But it would be nice to have a 128 PB USB drive, wouldn't it?)

On the other hand, FAT32's max file size of 4 GB is almost nothing now that phones can record 4K videos. Also, it's a little more difficult to format a drive larger than 32 GB to FAT32 on Windows 10.

These days, the only reason why you'd choose to format a drive to FAT32 is for compatibility. For example, if you need to boot up an old computer, maybe with a different operating system, and backup some of its files. But you'd need to be sure that none of those files are greater than 4 GB.

If you're sure you want to go with FAT32, here's how to format a storage drive on Windows 10.

How To Format A Thumb Drive Fat32 Mac

Important note: Before you format a drive, make sure that you backup all of your important files. In fact, make two backups, and keep one on a remote service like Google Drive or Dropbox.

Formatting a drive will delete all of the data that's currently on it.

How to use Windows File Explorer to format a USB drive to FAT32

A quick note about this method: it only works on USB flash drives that are less that 32 GB. If your USB drive is larger than 32 GB, check out one of the later methods.

With that out of the way, plug your USB drive into your computer and open Windows File Explorer.

Next, right-click on the drive on the left hand side of the File Explorer window and click 'Format':

In the window that pops up, ensure that 'FAT32' is selected. Also, feel free to rename the USB drive whatever you'd like:

You can leave the rest of the options alone. Just click start to format your drive.

Once it's done, your USB drive should be formatted to use the FAT32 file system.

To double check this, open File Explorer, right click on your USB drive, and click 'Properties'.

A window will pop up and you should see that the file system is now FAT32:

How to use Rufus to format a USB drive to FAT32

If your USB drive is larger than 32 GB, you'll need to use a third-party program like Rufus to format it.

There are lots of other programs that can format USB drives, but Rufus is really small and portable. This means you can stick Rufus right on a USB drive, plug it into any Windows computer, and format other drives on the go.

After you download Rufus, double click on the .exe file to start the application.

Make sure your USB drive is selected. Then, click the 'Boot selection' dropdown and select 'Non bootable':

Next, click the 'File system' dropdown and select 'FAT32'.

Also, feel free to change the name of your USB drive under 'Volume label':

Then, click the 'Start' button to format your drive. After a few seconds it'll be formatted to FAT32.

How to use PowerShell to format a USB drive to FAT32

While this method works with drives larger than 32 GB, it's really slow – even formatting a 32 GB drive can take up to an hour depending on your computer.

But, if you aren't able to use the previous two methods for some reason, this will work in a pinch.

First, click on the Windows Search Bar and type in 'powershell'. Then, click 'Run as administrator' to launch PowerShell with elevated privileges:

In the PowerShell terminal, enter the following command:

format /FS:FAT32 DRIVE_LETTER:

Use the File Explorer to double check your drive letter. My drive letter was D, so I entered format /FS:FAT32 D:.

Press Enter, make sure your USB drive is plugged in, and press the Enter key again to start the process:

Then go run some errands or something – it will take awhile.

Once the format command is finished, your drive should be formatted to FAT32.

In closing

Now you should be able to format a USB drive of any size to FAT32 on Windows 10. And with just a little modification, any of these methods can be used to format your drive to another file system like NTFS or ExFAT.

Now get out there and format all your USB drives. (But only after you backup everything important!)
