How to Remove “The Disk is Write-Protected” Error from USB Drives: Step-by-Step Guide

You get so frustrated when “The Disk is Write-Protected” error occurs when you try to save a file because the drive cannot write, which has to be related to write protection. This frequent problem can lock you from changing, erasing or adding new files to this storage device. In this guide, we will look at different ways to remove this write protection and regain full access of your USB drive.

Common Causes of the Error

Before looking for solutions, it’s useful to know why this error occurs in the first instance. Some of the biggest culprits include:

1. Physical Write-Protection Switch: Some USB drives feature a physical write-protection switch.
2. Corrupted File System: If the file system is corrupt, the drive may automatically disable write operations.
3. Virus or Malware: One kind of malicious software can change your USB settings.
4. Registry or Permission Settings: Your operating system may prevent write operations if the registry settings are incorrect.

Sometimes, the ‘Disk is Write-Protected’ error can occur due to partitioning issues on your USB drive. For example, if your USB drive is showing up as two drives in Windows, this could be an indicator of a corrupted partition. If you’re facing this problem, I’ve written a detailed guide on why USB drives show up as two drives and how to fix it. You can check that out here. Once you resolve that, you can proceed with the steps in this guide to remove the write protection.

So, let us get into the various solutions to fix the issue and make your USB drive function properly once again.

Method 1: Using Windows Diskpart Utility

The Windows Diskpart utility is one of the most effective methods to remove USB write protection. It is a built-in tool to manage your disk partitions and remove write protection at the command line level.

Well, use Diskpart to do this in the following manner:

Insert the USB drive to your PC. Type cmd in the Windows search bar and press Enter. Ensure you run as Administrator (right click: Run as Administrator)

Once the Command prompt window open, enter “diskpart” and hit enter. This would open Diskpart utility.

Now type “list disk” and hit Enter. This will show you all storage devices currently connected to your PC.

Compare the size of the USB drive with the list, and then identify it. Enter “select disk 2” (change 2 to the number of your USB drive) and hit Enter.

Then type “attributes disk clear readonly” and hit Enter. This command is to clear/write-protect from the selected disk. Be careful with this tool (Diskpart), selecting the wrong disk can destroy data.

You can type exit then press Enter to leave the Diskpart utility.

Now this should remove the Disk is Write-Protected error from your USB drive, close CMD and verify.

Method 2: Modifying the Windows Registry

If the Diskpart method doesn’t work, you can remove write protection by further tweaking the Windows Registry. This process uses the Registry Editor (Regedit) to modify system settings.

Warning: However, be careful when you are editing the Registry as a mistake can get your system into trouble. You should always back-up the target before modifying anything. For more details on safely working with the Windows Registry, refer to Microsoft’s official guide on Registry Editor.

Here’s what to do to adjust the registry:

Press Windows + R on your keyboard to open the Run dialog box. Type “regedit” and press Enter to open the Registry Editor.

In the Registry Editor window, Navigate to –HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies

If you don’t find “StorageDevicePolicies“, you can right-click on “Control” > New > Key

and call it “StorageDevicePolicies“.

Like this: In the right pane, right-click and choose New > DWORD (32-bit) Value

and name it “WriteProtect“.

Double click “WriteProtect” which will bring this up and set to 0

Close Registry Editor and restart your PC. Try accessing the USB drive after restarting to check if the Disk is Write-Protected error is removed.

Method 3: Look for Physical Write Protection

The problem may even be as simple as a physical write-protect switch on your USB drive. Most USB flash drives, particularly older ones or USBs meant for data secure storage, have a small switch that can be flipped to turn write protection on or off.

The following process includes checking for physical write protection:

1. Look for a tiny switch or slider on your USB drive.
2. If you do, ensure that it’s in the “unlocked” position.
3. If the problem vanishes when you move the switch, you’re in business!

If your USB drive lacks a physical switch or moving it doesn’t help, then refer to the next method.

Method 4: Formatting the USB Drive

Formatting your USB drive can sometimes fix the Disk is Write-Protected error, especially if they’re due to file system corruption. This process will, however, wipe everything from the drive, so ensure you have backed up any files you want to keep.

To format your USB drive:

1. Go to File Explorer and right-click on your USB.
2. Choose “Format” from the context menu.
3. File system: you can select the one you prefer (NTFS is recommended for larger drives).
4. Press the “Start” button to open the formatting tool.

To format the drive via Disk Management:

1. Go to Start, right-click on it, select Disk Management.
2. Find your USB drive in the list of drives.
3. To do this, right-click on the USB drive partition and select “Format”.
4. Follow the instructions to finish Date Format.

Method 5: Using Third-Party Software

If all these methods fail, you may try a third-partysoftware solution that is actively pointed to removing the Disk is Write-Protected error from USB flash drives. Such tools typically come with a user-friendly interface and are capable of addressing most write protection causes.

Some popular options include:

• USB Write Protector
• USB Disk Storage Format Tool

If you download third-party software, ensure you download only from credible sources and scan the files for viruses before installation.
