How to Wipe exFAT Drive on Windows or macOS?

PAGE CONTENT:

Wiping an exFAT drive - whether it's a local partition, USB flash drive, SD card, or external hard drive - can be essential when preparing a storage device for resale, troubleshooting file system issues, or starting with a clean slate. exFAT, short for Extended File Allocation Table, is a Microsoft-developed file system that offers wide compatibility across operating systems, including Windows and macOS.

Unlike simple formatting, wiping goes a step further by securely erasing all data, reducing the chances of recovery. In this guide, we'll walk you through everything you need to know about securely wiping an exFAT drive on both Windows and macOS, using built-in tools and trusted third-party software.

What Does "Wipe" Really Mean?

Before diving into the steps, it's important to understand the terminology.

• Formatting a drive removes the file table but not the actual data until it's overwritten.
• Wiping or secure erasing ensures that data is overwritten and unrecoverable.

There are two primary types of wiping:

1. Quick Wipe (Reformatting): Deletes file references but data can often be recovered with tools.
2. Secure Wipe (Overwrite): Writes random data over the sectors, making recovery practically impossible.

If you're just reusing the drive for personal use, a quick wipe may suffice. But for sensitive data or resale, a secure erase is the safer bet.

Precautions Before Wiping exFAT Drives

Wiping is irreversible, so take these steps before proceeding:

• Backup Important Data: Use an external backup or cloud storage.
• Check File System Type: Ensure the drive is indeed using the exFAT file system:
  • On Windows: Right-click drive > Properties
  • On Mac: Open Disk Utility and select the drive to see its format
• Ensure Drive Is Not Write-Protected: Some USBs and SD cards have physical switches that prevent writing or erasing data.

How to Wipe exFAT Drive on Windows?

Method 1: Quick Format via File Explorer [Data is recoverable]

Best For: Casual users, basic reuse, non-sensitive data (formatted data can be recovered).

The quickest way to wipe an exFAT drive on Windows is through File Explorer's built-in format feature. This method is sufficient if you're preparing the drive for personal reuse and don't need to worry about data recovery.

Steps:

Step 1. Connect the exFAT drive to your computer.

Step 2. Open File Explorer and locate the drive.

Step 3. Right-click the drive and select Format.

Step 4. Under File system, keep it as exFAT or change it if needed.

Step 5. Check or uncheck Quick Format depending on your needs.

Step 6. Click Start to begin the wipe.

💡 Note: Unchecking "Quick Format" will result in a more thorough wipe but takes longer.

Method 2: Wipe via Disk Management Tool [Data is recoverable]

Best For: Repartitioning, repairing drive issues, full formatting (formatted data is not lost for good and still can be recovered by data recovery software).

Disk Management provides a visual interface for managing disks and partitions. If your drive isn't appearing correctly or has become corrupted, this tool can help wipe and reconfigure it from scratch.

Steps:

Step 1. Press Windows + X and choose Disk Management.

Step 2. Find the exFAT drive in the lower panel.

Step 3. Right-click on its partition > Delete Volume.

Step 4. Right-click again > New Simple Volume.

Step 5. Format using exFAT or another file system.

Method 3: Wipe Using Command Prompt (diskpart)

Best For: Advanced users, full control, full format. (Lost data is recoverable.)

Using diskpart gives you granular control over the disk and ensures complete data removal. Unlike File Explorer, it can delete hidden system partitions or remove malware remnants.

Steps:

Step 1. Press Windows + R, type cmd, and run as Administrator.

Step 2. Type diskpart and press Enter.

Step 3. Type list disk to see connected drives.

Step 4. Identify your exFAT drive and type select disk X (replace X with your drive number).

Step 5. To clean the drive:

clean

(Optional) To securely overwrite data:

clean all

This performs a zero-fill wipe across all sectors - much more secure.

Step 6. To reinitialize:

create partition primary
format fs=exfat quick
assign

💡 Note: The data which is erased by Clean or Clean All or Format commands is not lost for good and can be recovered by data recovery software.

Method 4: Wipe exFAT Drive with Disk Wipe Software [Data is unrecoverable]

Best For: Wiping sensitive data with multi-pass algorithms (DoD 5220.22-M, Gutmann or more). (Erased data is lost for good, no way to recover it.)

If you're donating, reselling, or disposing of a drive containing sensitive data, a secure erase tool is recommended. These tools go beyond native Windows functions by overwriting the drive multiple times to ensure data cannot be recovered with forensic software.

Donemax Data Eraser for Windows is one of the best disk wipe software. It offers certified data erasure standards including HMG Infosec Standard 5, NIST 800-88, Peter Gutmann's algorithm, DoD 5220.22-M, U.S. Army AR380-19, DoD 5220.22-M ECE for secure erase. You can use it to securely wipe your exFAT drive and permanently erase all data from the drive.

Step 1. Download and install Donemax Data Eraser on your computer, then run it on your computer. Ensure the exFAT drive is connected to this computer.

Step 2. Choose Erase Hard Drive mode. This mode can help securely wipe the entire drive and permanently erase all data (existing data, hidden data, deleted/formatted/lost data, etc) from the drive. Just select the exFAT drive.

Step 3. Click on Erase Now button. Then you can choose a data erasure standard, click Continue.

It will securely and permanently erase all data from the exFAT drive.

For maximum security, choose a multi-pass overwrite option, especially when handling business, medical, or personal identity-related files.

💡 Note: Once the process gets finished, all data stored on the exFAT drive is lost for good, can't be recovered by any method.
