How to change FAT32 to NTFS on Mac

Despite its age, FAT32 is still widely used for USB drives, digital cameras, MP3 players, and other environments where older computer systems are still in use, thanks to its compatibility across different operating systems and devices.

However, FAT32's limitations, including a 4GB file size cap, a maximum volume size of 2TB, and a lack of security and reliability features, might prompt a switch to NTFS. As Windows' default file system, NTFS excels with larger file and volume support, enhanced performance, faster file handling, and improved security and data integrity.

If you're considering this transition, this article will guide you. Keep reading to discover the steps to convert your USB, SD card, or external hard drive from FAT32 to NTFS on Mac.

How to change FAT32 to NTFS without formatting on a Mac?

Wondering whether you can change FAT32 to NTFS on Mac without formatting? 

The answer is no. The process of changing file systems on Mac, especially from something as different as FAT32 to NTFS, inherently requires formatting. This is because each file system has its own way of managing data, and these methods are not directly compatible with each other.

When you format a drive from FAT32 to NTFS on Mac, the following processes are involved:

Data Erasure: All existing data on the drive is erased. This is necessary because the way data is stored and managed in FAT32 is fundamentally different from how it's done in NTFS.

File System Structure: Formatting establishes a new file system structure on the drive, including its method of storing files, directories, and the metadata associated with them.

Feature Utilization: NTFS has features that FAT32 does not, like enhanced support for larger files and volumes, improved security with file-level permissions, efficient file management, and journaling to ensure file system integrity by logging transactions. These features can only be implemented by establishing NTFS from scratch.

How to convert FAT32 to NTFS on Mac without losing data?

If you want to change FAT32 to NTFS without losing data on Mac, you must first back up the drive. The easiest way to do that is to transfer the important files to another external drive or your Mac. Once your data is backed up, choose one of the following ways to format it from FAT32 to NTFS.

 Warning: Ensure you have backed up files on the FAT32 drive before proceeding!

Way 1: Change from FAT32 to NTFS on Mac with iBoysoft NTFS for Mac

If you've previously formatted a drive on Mac, you likely have noticed that NTFS is not available in Disk Utility.

That's because macOS has only read access to NTFS but can't write to it by default. This is also the reason why you'll need an NTFS driver like iBoysoft NTFS for Mac to format drives to NTFS on Mac.

This tool grants you full read/write access on Mac, enabling you to convert non-NTFS formats (including FAT32) to NTFS, repair, mount, and rename NTFS drives, and copy, move, delete, modify, and create new folders on the NTFS drive. It is compatible with all macOS versions from macOS 10.13 High Sierra onwards and supports Intel-based, T2, M1, M2, and M3 Macs.

An additional notable feature is its ability to automatically mount NTFS drives connected to your Mac without requiring you to launch the app first. Here's a checklist of its full features:

Way 2: Change from FAT32 to NTFS on Mac via Terminal

There's also a less-recommended way to format FAT32 to NTFS on Mac: by running commands in Terminal. It's only applicable on macOS Monterey or earlier versions. On macOS Ventura or later, it will return the error "Formatting is not supported by: NTFS ntfs Windows NT File System (NTFS)."

Besides, it doesn't empower you to write data to the formatted NTFS drive, although it allows you to format it to NTFS. If you want to work with the NTFS drive on Mac, you'll still need a third-party driver like iBoysoft NTFS for Mac.

If you still decide to give it a try, use the following steps:

  1. Open Finder, then launch Terminal from the Applications/Utilities folder.
  2. Type the following command and hit Enter to list all drives connected to your Mac.diskutil list
  3. Look for the disk identifier of your FAT32 drive or partition. (For example, if it's a drive, the identifier could be disk2; if it's a partition, the identifier may be disk2s3.) 
    Check disk identifer of the FAT32 drive or partition
  4. Input one of the following commands and hit Enter to convert FAT32 to NTFS.
    For a FAT32 drive:diskutil eraseDisk NTFS name /dev/disk_identifierE.g., diskutil eraseDisk NTFS Backup /dev/disk2 
    For a FAT32 partition:diskutil eraseVolume NTFS name /dev/disk_identifierE.g., diskutil eraseVolume NTFS Backup /dev/disk2s3
  5. Wait for the erase process to complete.
