How to Erase Hard Drive Data in Windows 10

Data has a life span. After the end of life, data must be securely erased from the system to prevent incidents such as data breach, identity theft, and unauthorized access to your sensitive information.

Ideally, users tend to delete particular files or format entire drive volume to destroy and prevent access to their confidential files and sensitive information. However, a few users know that the deleted and formatted files can be potentially recovered from any storage media with the help of publically available data recovery software.

To prevent this eventuality which can lead to data breach, you must use a secure file erasure method. For wiping confidential data, it’s recommended that you use methods and tools that are compliant with international data erasure standards.

To help you, we have outlined a few secure erase methods that you can use to erase hard drive data in Windows 10.

Steps to Erase Hard Drive in Windows 10

Follow them carefully to erase hard drive data in Windows 10 beyond the scope of recovery.

Method 1: Full Format

Generally, when you format a drive volume, it is quick formatted. That’s because the ‘Quick Format’ option is selected by default.

In Quick Format, only the Master File Table or File Allocation Table is erased, but data remains intact on the drive that can be recovered quickly.

However, when you uncheck the ‘Quick Format’ option, the system performs a full format, which is quite slow. That’s because full format overwrites entire drive volume with zeroes and destroys the existing recoverable data.

When to Use

Use full format when you need to wipe data from the entire drive volume and get rid of sensitive data.


You can’t full format C: drive volume in Windows 10. It can’t erase anything from the C: Drive, which contains most confidential information about your online and offline activities in the form of application traces, system traces, and internet activities.

Method 2: SDelete

SDelete is a Microsoft utility that erases empty storage space on a drive volume that may contain previously deleted confidential files. The utility is safe to work with, but it runs via Command Prompt terminal. To use SDelete to wipe your drives empty storage, follow these steps:

  • Download SDelete utility from Microsoft Internals website
  • Extract the compressed folder on the Desktop
  • Press and hold the ‘Shift’ Key and right-click on the ‘Desktop.
  • Choose ‘Open command window here.
  • Now type sdelete –p 5 D: and press the ‘Enter’ key

Where ‘–p’ denotes passes, number ‘5’ number of passes, and ‘D:’ is the drive volume letter. You can increase or decrease the number of passes as per your wish.

When to Use

If you are familiar and conformable with Command Line tools, use SDelete. You can delete your files from your storage media and then run SDelete utility to wipe empty storage and destroy recoverable data with DoD 5220.22-M data sanitization standard.


  • You need to wipe entire drive volume every time you wish to destroy a deleted file. Thus, it’s not ideal if you often delete confidential files from your Windows 10 PC.
  • Also, you can’t delete an existing file. It also increases disk usage by 100%, which hinders system performance, and the user would experience system lag and freezes while SDelete is working in the backend.
  • Running SDelete on internal drive frequently also affects the hard drive life.
