Need to Remove Write Protection from a USB

“I have a 64GB flash drive that I need to format, but when I try, I am told it is protected and the protection must be removed. I have seen directions about using Regedit, but would feel better getting the direction from you, rather than an unknown group on the 'net. Can you provide some specific instructions? Thx.”

The good news is that there are multiple methods to remove this protection and erase the data stored on your USB drive. In this article, we will discuss various ways to overcome this challenge and ensure your USB drive is ready for future use.

Solutions on How to Wipe a Write-Protected USB

Solution 1: Change Pen Drive Read-Write Properties

When a USB is write-protected, attempts to delete, format, or modify files will be blocked by the system, and you may see an error like “The disk is write-protected” when trying to format or erase the drive. There is a manual way for you:

1. Go to My Computer/This PC and under Devices with Removable Storage.

2. Look for your pen drive device. Right-click on it and click Properties.

3. Click Edit, in the pop-up box, sometimes there's an option to Remove write protection.

Solution 2: Remove Write Protection Using Diskpart Command

Diskpart is a powerful Windows utility that can be used to manage disks and partitions. This tool allows you to remove the write protection from your USB drive and format it if needed.

Steps to Remove Write Protection Using Diskpart:

1. Press Windows + R to open the Run dialog box, then type cmd and press Enter.

2. In the Command Prompt window, type diskpart and hit Enter.

3. Type:

Tip: Be cautious when using Diskpart, as selecting the wrong disk can lead to data loss.

Solution 3: Disable Write Protection Through Windows Registry Editor

Sometimes, write protection on a USB drive is caused by a registry setting in Windows. In such cases, you can modify the Windows registry to remove the write protection.

Steps to Remove Write Protection via Registry Editor:

1. Press Windows + R to open the Run dialog box, type regedit, and press Enter.

2. Navigate to the following registry path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies

3. If the StorageDevicePolicies key doesn’t exist, you will need to create it. Right-click on Control, select New > Key, and name it StorageDevicePolicies.

4. In the StorageDevicePolicies folder, look for a DWORD value named WriteProtect. If it doesn’t exist, right-click the folder create a New > DWORD (32-bit) Value and name it WriteProtect.

5. Set the value of WriteProtect to 0 (zero). This disables write protection.

Warning: Modifying the registry can have serious consequences if done incorrectly. Always back up the registry before making changes.

Bonus: What is Write Protection and Why Does It Happen?

Write protection is a feature that prevents data from being modified or deleted from a storage device, such as a USB drive. This can be a useful safety mechanism, particularly in preventing accidental deletion of important files, but it becomes problematic when you need to erase or update the contents.

Common Causes of Write Protection:

  • Physical Write Protection Switch: Some USB drives come with a physical switch that can lock the drive in write-protection mode.
  • Windows Registry Setting: In certain cases, a registry key may be set to prevent write access to your USB device.
  • Malware or Virus: Certain malicious programs can apply write protection to USB drives as a way to secure their files.
  • Corrupt USB Drive: A faulty or corrupted USB drive might automatically apply write protection to prevent further damage.

By using Diskpart, the Registry Editor, or software like AOMEI Backupper, you can easily remove write protection and format your drive. Following the methods outlined in this guide will help you regain full control of your USB and prevent future issues with write protection.
