“I have been trying to format my pen drive, but every time I do, I get “The Disk is Write Protected” error. How to format a write protected USB on Windows?”

This is one of the most commonly asked questions related to the formatting of USB drives these days. With the advancement in technology, USB drives have also evolved and become more secure. To protect the drive, the system of write protection was introduced, which is still not known by a lot of people. Therefore, if the USB drive you are trying to format is write protected, then you might get a similar error too. Don’t worry – it is quite easy to learn how to format a write protected pendrive on both Windows and Mac. Here’s a detailed guide on the same!

Part 1: What is "Write Protection" on a USB Drive?

USB or Thumb drives are extensively used to store or transfer data from one source to another. Although, while doing so, they often suffer from numerous privacy and security issues. To resolve this, the concept of “write protection” was introduced. Ideally, when the feature is turned on, then the USB drive is switched to a read-only mode. This means, users can only read data from the USB drive, but can’t write anything on it. Additionally, they can’t delete anything from the USB drive or format it.

If you want to protect your pen drive from a malware attack or you are connecting it to a public computer, then enable the write protected feature. Also, if you have sensitive data on the pen drive that you can’t let go off, then you can turn it on to avoid any accidental data deletion.


Part 2: Causes of "The Disk is Write Protected" Error

Before we dive into the details and learn how to format a write protected USB, it is important to know its cause. Following are some of the major reasons for getting this prompt while formatting the drive.

  • Chances are that you might have turned on the write-protection switch by mistake and forgot to disable it afterward.
  • The USB drive can enter the read-only mode via firmware setting or update as well.
  • Sometimes, users also get this error when the USB drive is corrupt or has a bad sector.
  • A malware or virus can also be one of the reasons for this problem.
  • Your system might block the USB drive or a change in its registry can also be an issue.
  • If your pen drive is physically damaged, then it can also enable this feature without you noticing.

Part 3: How to Format Write Protected USB

The good thing is that you can easily disable the write protection feature on a USB drive and later format it. To do this, you don’t need any write protected USB format tool at all. All you need to do is follow two simple steps – disabling the write protection feature and formatting the drive.

Step 1: Check and Unlock USB Flash Drive

Firstly, check if the USB drive that you are using is write protected or not. If it is, then simply disable this feature in the following way.

Turn Off the Write-protect Switch

This is the easiest and the quickest solution to disable the write protection feature on a thumb drive. Most of the USB drives have a write protected switch located on the side. By simply sliding the switch, you can turn the feature on/off. Move it in the upward direction (or sideways towards the unlock symbol) to disable this feature. The exact location and movement of the switch might vary among different models.

Step 2: Format A Write Protected USB/Pen Drive

After disabling the write protection feature, you would be able to format the USB drive in the same old way. Though, if you are still facing some issues, then follow these methods to format a write protected USB.

Method 1: Using the Registry Editor (Windows)

The first technique to format write protected USB drive is by using the Registry Editor on Windows. It is a dedicated system utility tool that stores all the vital details and parameters related to Windows settings. To learn how to format write protected USB drive via the Registry Editor, follow these steps.

1. Firstly, launch the Registry Editor tool on your Windows. To do this, you can just press the Windows + R keys on the keyboard. You can also launch the Run prompt and enter the “regedit” command.

2. This will launch the Registry Editor application on the screen. From here, you need to navigate to HKEY_Local_Machine > System > Current Control Set > Control > Storage Device Policies and open the “WriteProtect” file.

3. If you can’t find it, then right-click the “Control” folder and create a new policy by right-clicking it. Name it “StorageDevicePolicies” (without spaces) and create a new DWORD as “WriteProtect”. Make sure the value data field is marked as “0”.

4. In case if the WriteProtect file already exists, then double-click to open it and change the value data to “0”. Just make sure that you are logged-in as an administrator while doing so. Once it is done, you can format the USB drive the usual way.

Method 2: Using Diskpart (Windows)

If you can’t find the write protection switch on your USB drive, then don’t worry. You can manually enable or disable it as well via the Command Prompt. For instance, Windows users can take the assistance of the Diskpart (Disk Partition) utility command to do the same. In order to format a write protected USB drive, simply follow these basic steps.

1. Firstly, connect the USB drive to the system and launch the Command Prompt application from the Start menu. Once it is launched, enter the “Diskpart” command to launch the utility tool.

2. Enter the “list disk” command to view the attached drives. From here, identify the disk identifier from the list.

3. Now, you need to pick your USB drive using the “select” command followed by its identifier.

4. Then, type the “attributes disk clear read only” command, press enter. This will clear the read-only feature from the USB drive.

5. Don’t exit the Command Prompt now as you can also format the USB drive from here. Since the USB drive is already selected, enter the “clean” command to wipe it.

6. Subsequently, enter the command “create partition primary” to create a partition on the drive.

7. In the end, you can use the “format” command to wipe the entire disk and format it in a desired file system. Just type the file system you wish to format it to after the “format” command. For instance, to format the disk to an NTFS system, you can enter “format fs=ntfs”.

Sit back and wait as your USB drive would be formatted to the entered file system. The application will let you know, letting you disconnect the drive or use it the way you like.

Method 3: Using Disk Utility (Mac)

If you have a Mac and you can’t seem to format a write protected USB drive, then don’t worry – you can use its native Disk Utility tool. Therefore, instead of downloading any third-party write protected pen drive format tool or software, you can simply follow these basic steps.

1. Connect your USB drive to your Mac and from the Finder, go to Applications > Utilities > Disk Utility.

This will start the formatting of the USB drive in the selected file format. If you wish to use it only on Mac, then you can go with an Apple exclusive file system like HFS+. Though, it is recommended to use a more universal file system like FAT or exFAT to use it on Windows as well.
