While Windows employs two major file systems: NTFS and FAT. FAT was inherited from old DOS and has exFAT as its later extension. In addition, the ReFS file system was developed as a new generation file system for server computers starting from Windows Server 2012.
That is to say, only FAT32 and exFAT can work on both Mac and PC. If you want to share digital files between Mac and Windows system easily, you must convert WD My Passport to FAT or exFAT. Here are three ways to format a WD My Passport, follow any one of them to convert to FAT.

Difference Between FAT32, exFAT, and NTFS
FAT is known as the File Allocation Table. The successive major versions of the FAT format are named after the number of table element bits: FAT12, FAT16, and FAT32. FAT32 is the oldest of the three file systems available to Windows. Individual files on a FAT32 drive can’t be over 4 GB in size. A FAT32 partition must also be less than 8 TB, which admittedly is less of a limitation unless you’re using super-high-capacity drives.
exFAT, Extended File Allocation Table, is optimized for flash drives. It was added to older versions of Windows with updates to Windows XP and Windows Vista. This file system doesn't have the limitations of FAT32. You can use it when you need a bigger file size and partition limits than FAT32 offers.
NTFS, NT File System, is the modern file system Windows likes to use by default. It is packed with modern features not available to FAT32 and exFAT. However, it only works with all versions of Windows, but read-only with Mac by default.
If you want to use WD My Passport or any other hard drive on Mac and PC, you need to format a Western Digital My Passport external hard drive in exFAT or FAT32 format.

You might have heard about the terms of FAT32, NTFS or exFAT and need to decide which one to choose as the best file system for your SD card or USB flash stick. Don’t worry. In this article, we are going to introduce the three file systems so that you’ll know the difference between FAT32, NTFS and exFAT as well as their pros & cons and compatibility.
In order to avoid problems like slow USB transfer speed or “the file is too large for the destination file system”, it is necessary to know all the features and limitations of different file systems. For example, Windows operating system gets installed making the use of NTFS file system for partition formatting. In a similar way, FAT32 is used for files in removable disk drives and other such devices which have interface-based storage to keep the files. Basically, the exFAT file system is the modified derivation of FAT32. Keep looking if you need more information to differentiate FAT32, NTFS and exFAT files systems.
File System
While we are working with computer and other storage devices, all the workabilities are based on some kinds of algorithm and coding. There are some rules which are implemented to bring out that feature and function of every system. The file system is one of such sets of rules which are derived to process the data storage and keep it secured in a storage device. The computation system is brought in use to store the files in a secured manner.
File system surely is important to make the data stored with its value in the storage device. If it is not there, then only the undefined data will be stored in it. There are many types of file systems which can be used to store the files in different storage options or devices. They are Flash File System, Disk File System and many others. FAT32, NTFS and exFAT are the types of Disk File System.

How to format a USB stick to FAT32, NTFS or exFAT:
It is very easy to format a storage device to any of the three file systems on a Windows computer. Just right click on the disk drive in Windows File Explorer and choose Format, then you will get the options.
Allocation Unit Size
Allocation Unit Size, also known as Cluster Size is an important part of file systems. On a partition of the file, the smallest space occupied by it is termed as Allocation Unit Size. You can vary the file size as per your need ranging from 4096 to 2048K. At the time of formatting, the default allocation unit size is applied to all the files. The file is stored into the same number of pieces as its allocation unit.
Tips: Due to the mechanism of file systems, the data you deleted is not immediately removed from storage devices before new data is saved. Therefore, it is still possible to recover lost files from SD card, hard drive, USB flash stick or computer with a good data recovery software.
1. FAT32 File System
FAT stands for File Allocation Table which is one of the oldest file systems used for storage of data. Initially, it was designed as an 8-bit FAT file system to store the data into an 8-inch floppy disk.
With many modification and advancement, FAT32 was introduced in 1995. It is a great aid to store the files into the removable or external storage device or drives. Up to 4 GB of single file and a total of 8 TB as the maximum disk size for FAT32. So, it is used to store only the small files not the apps or files having a large size. To overcome this limitation of FAT32, NTFS is used.
Compatibility: All version of Windows, Mac, Linux, and almost anything with a USB port.
Pros:
- It is an amazing file system to store files in flash drives.
- It is lightweight and has cross-platform compatibility.
Cons:
- You can only store files having a size-limited up to 4 GB and partition size up to 8 TB.
2. NTFS File System
As we have already seen that FAT32 is not capable to store the large files. To nullify that limitation, NTFS is selected as the default file system with modern techniques to store the file with a large file and partition size.
NTFS or New Technology File System came into use in 1993 with the introduction of Windows NT 3.1 operating system. It is capable to store almost all types of files with a high range of file size limits. In other words, it is capable to store all types of files available at present.
NTFS is also featured with disk usage quotas, reparse points, sparse file support, file-level encryption and distributed link tracking. Moreover, it is also designed so as to display backward compatibility. That means, it is not limited to be used with any latest version. You can use this file system to store using any previous versions. However, this file system is somehow limited to Windows XP and later versions of Windows. You can only read the formatted files of NTFS using Apple’s Mac OSX. You can edit the file of NTFS using some particular versions of Linux.
Compatibility: All version of Windows, Microsoft Xbox One, Mac (read-only) and Linux (write support for some versions)
Pros:
- There is an inexhaustible limit of files to be stored using NTFS. You can store a file of any partition size.
- It is mainly used to store files in internal hard drives.
- It is used for the installation of software as well.
Cons:
Ntfs Fat32 Mac Os
- It is compatible with limited cross-platform.
- You can not edit the NTFS formatted file using Mac.
3. exFAT File System
exFAT or extended FAT is the modified and advanced file system which is used to fill the space of FAT32. It is mainly used in modern digital cameras and in ball games. Moreover, it is also used to format the high capacity SDXC memory cards. It is capable to support the formatting storage of large files and is lightweight as well. This is the reason why exFAT is considered in many fields where there is a need to support files larger than 4 GB. exFAT SD card is used in daily life for many purposes where the FAT32 is not capable to support due to its limitations of file size. You can copy a full HD movie easily using exFAT SD card and do many other such works.
At present, Microsoft is looking after the US Patent 8321439 which is developed for accelerating the file search speed. It is named as Quick Fine Make Lookup through which one can find his/her file by using Name hashtag or such keywords. This set of the specification has not yet brought up for the exFAT file system due to which this file system users are using a restricted licence over their files. They can get access to the file’s licence completely after the release of full specification set by Microsoft. Due to this, vendors from many countries are not using the exFAT file system for the open-source operating system or any commercial software.
Compatibility: Windows XP and later versions, Mac OS X and later versions, Linux (using FUSE), Android
Pros:
- It is lightweight as compared to NTFS.
- It is an intermediate solution over FAT32 and NTFS.
- You can read/write the exFAT formatted files using compatible Mac version as well.
- More devices support exFAT than NTFS.
Fat32 Vs Ntfs
Cons:
- Its usage is restricted by Microsoft and does not give complete access over the licence to the user.
Verdict
Hence, you have seen all the basic and important features of these three file systems. Now, it will be easy for you to differentiate these file systems and select them appropriately for storing and formatting your files. Generally, exFAT is ideal for flash drives, NTFS for internal drives, and FAT32 is more widely supported by devices. However, in some cases, it is necessary to format a storage device as a file system against the regulation above in order to make the device work smoothly.
