How to wipe a drive on Windows 10 or Windows 11

Whether you’re donating your computer, replacing a drive, or just want a clean start, wiping a drive is an important step to protect your personal data. But it’s not just about hitting delete—there’s a right way to do it.

At Asurion, we help people take control of their tech every day, including managing storage and security. Here's how to safely and completely wipe a drive on Windows 10 or Windows 11.

What does it mean to wipe a drive?

Wiping a drive means securely erasing all data so it's difficult or impossible to recover—files, programs, and even your operating system if it's your main drive. It’s different from deleting individual files, which can often be recovered later.

If you’re preparing a drive for resale, disposal, or a clean reinstall, wiping it makes sure your personal information is gone for good.

Tips before you wipe a drive

Before you get started, keep these tips in mind to make sure your data stays safe.

• Back up your files. Once a drive is wiped, your data is gone. Save anything important to the cloud or an external drive.
• Double-check the drive. Make sure you’re selecting the right one—there’s no undo.
• If you’re donating or selling your PC, use the clean data option to prevent data recovery.

How to wipe your system drive (C:)

To wipe your main Windows drive, you’ll need to reset or reinstall Windows. Here are two ways to do it:

Option 1: Use Reset this PC

1. Go to Settings > System > Recovery.
2. Under Reset this PC, click Reset PC.
3. Choose Remove everything.
4. Select Local reinstall or Cloud download.
5. On the next screen, select Change settings, then turn Clean data? to Yes.

This will wipe your drive and reinstall Windows, removing all files and apps.

Option 2: Use installation media (for full reinstall)

1. Download the Media Creation Tool from the Microsoft website.
2. Create a bootable USB drive.
3. Boot your PC from the USB.
4. When prompted, choose Custom: Install Windows only.
5. Select your system drive and delete the partition before reinstalling.

How to wipe a secondary or external drive

If you’re wiping a drive that doesn’t run Windows (like an external or secondary drive), here’s what to do.

1. Open the Start menu and search for This PC.
2. Right-click the drive you want to wipe and select Format.
3. In the Format window:
   • Choose File system: Leave it as NTFS unless you're using the drive on a Mac.
   • Check Quick Format (or uncheck it for a deeper wipe).
4. Click Start to begin.

For extra security, uncheck Quick Format to fully erase data—this will take longer but is harder to recover.

FAQ

Can I wipe a drive without deleting Windows?

Not if it’s your main drive. Wiping your C: drive will remove Windows too—but you can reinstall it during the process.

What’s the difference between Quick Format and Full Format?

Quick Format removes file references but not the data itself. Full Format writes over the data, making it harder to recover.

How do I wipe a drive if I can’t log into Windows?

Create a bootable USB using the Windows Media Creation Tool, then boot from the drive to format and reinstall.

Is it safe to use third-party wipe tools?

Yes, but Windows has everything you need for basic drive erasure. Stick with trusted tools if you choose a third-party option.

Will wiping a drive fix performance issues?

It can, especially if you're reinstalling Windows afterward. Just make sure the drive itself isn’t failing.
