The Disk is Write Protected Error When Formatting USB Drive: Fix

How to Fix “The Disk is Write Protected” Error While Formatting USB Drive?

If you have ever tried formatting a USB drive and encountered the “The disk is write protected” error, you’re not alone. This common issue prevents users from making changes to their USB flash drive, SD card, or external hard drive.

The possible root cause often lies in the read-only attribute being set to “Yes.”

In this article, we will explain why this happens and show you how to remove write protection using the Diskpart command in Command Prompt (CMD).

The “The disk is write protected” error can be frustrating, but with the Diskpart command, you can easily remove the read-only attribute and regain full access to your USB drive.

By following these simple steps, you can regain full control over your USB device and format it without errors.

Why Does “The Disk is Write Protected” Error Occur?

Write protection on a USB drive can be caused by several factors, including:

Physical Write Protection Switch: Some USB drives and SD cards have a small switch that enables write protection. Make sure it’s turned off.
Corrupt File System: A damaged or corrupted file system can make the drive read-only.
Registry or Group Policy Settings: Some system policies may block writing to external drives.
Virus or Malware Attack: Some malicious programs can change permissions and lock your drive.
Read-Only Attribute Set to Yes: This is one of the most common reasons and can be checked using Diskpart in CMD.

If you have verified that the physical write-protection switch is off and the problem persists, let’s proceed with removing the read-only attribute using Diskpart.
