How to Remove Write Protection from a USB

USB memory sticks and similar transferable data storage devices are convenient if you want to have your photos, media, or work files ready to go. It’s been quite some time since these storage devices have become the most prevalent method for storing digital data. However, sometimes it might happen that you can’t transfer your files onto a USB stick because write protection is activated.

Failed write attempts can be quite an inconvenience on a USB stick. Luckily, there are quick and easy methods to solve the write protection issue, whether you’re on a Windows PC or a Mac. There’s even a solution if you’re working on a Chromebook.

Note: Some SanDisk USB sticks (flash drives) and possibly other brands have an internal protection mechanism. According to SanDisk, if the USB drive experiences a power fluctuation or other potentially damaging error, it shuts off write access, and there is no way to get it back. They expect you to copy the data to another drive and replace it.

Check for a Write Protection Switch First

Before we go into details about write protection removal in different operating systems, there’s one thing to check first. Some data storage units have a physical switch for toggling write protection on or off.

Take the USB stick you’ve tried to write to and look for that switch, usually located on the side, and it might also be labeled as “Lock” or “Write Protection.” Switch it to the other position, reinsert it, and then transfer data to the memory stick again.

If that works, your problem is solved, and all you need to do is ensure the switch doesn’t accidentally get moved in the wrong position again. If there’s no switch (most common), or you still can’t write to the USB, you’ll need to employ other methods. Let’s get started!

Remove USB Write Protection using Windows

There are several ways to remove write protection from a USB stick if you have a Windows PC. Let’s take a look at some of them now.

Turn Bitlocker Off to Disable USB Write Protection

Since Windows 7, BitLocker got integrated into Windows 7/Vista Enterprise and Ultimate, and Windows 8 and above Pro and Ultimate editions to protect your data with encryption. The software primarily gets used for internal drives, but it can also encrypt USB sticks/drives. Other versions of Windows like Home editions require a separate download to decrypt the data when it comes to USB encryption. This scenario also applies when using macOS. Yes, Windows has a Bitlocker decryption tool for Macs too. Regardless, Bitlocker is off by default, but you may have activated it before and forgot about it, or someone else did it.

How to Turn Off BitLocker on a USB Stick

To turn off BitLocker on a USB stick, you must have the password or recovery key. If you don’t have either option, you’ll have to reformat the drive. If you have the key or password to BitLocker, follow the steps below.

  1. Open “File Explorer” and look for the storage device you have in mind. If the icon has a padlock, BitLocker was enabled for the device.
  2. Right-click on the icon and go to “Manage BitLocker.” This step takes you to the BitLocker Drive Encryption window, where a list of all storage units and their encryption status display.
  3. All you need to do now is click on the protected USB drive and select “Turn Off BitLocker.” Enter the password or select other options and choose to enter the recovery key. The status shows that the device is getting decrypted and, upon completion, BitLocker is turned off.

After you’ve disabled BitLocker, try to copy something on the USB stick again and see if the problem got resolved.

Use Diskpart to Disable USB Write Protection

Diskpart is a command tool that lets you manage all storage units detected by the computer. To remove write protection using Diskpart, follow these steps:

  1. First of all, check and remember (or write down) the storage capacity of the USB device. This suggestion comes in handy later. After you’ve confirmed the space limit, plug the USB stick into the computer port.
  2. Launch “Command Prompt.” You can do this either by pressing “Windows key+R” and typing “CMD” or searching for Command Prompt from the “Start Menu.” If you see the “Access is denied” message, right-click on Command Prompt and choose “Run as Administrator.”
  3. In Command Prompt, type “diskpart” and press “enter.” Then, type “list disk” and press “enter” again.
  4. You’ll see a list of all storage drives, named Disk 0, Disk 1, and so on. This step is where you’ll need the capacity information to identify your USB device. Compare it to the “Size” column, and you’ll find the disk number.
  5. Type “Select disk #”, where “#” is the disk number. For example, if your USB was Disk 1, type “select disk 1” without quotes, then hit “enter.”
  6. Type “Attributes disk clear readonly” and press “enter.” Yes, “attributes” has an “s” and “readonly” is one word.
  7. Finally, wait for the write protection removal to finish, type “Exit”, then hit “enter” to close the command prompt window.
  8. Restart your PC and try writing on the USB stick again after the system has rebooted.

Use the Windows Registry to Disable USB Write Protect

Going into the Registry is not recommended if you’re not an experienced user. The wrong input could seriously affect your system performance or render it unresponsive. Don’t worry, though. Even if you’re not familiar with the under-the-hood features, you’ll be able to remove the write protection if you follow our method very carefully. Just ensure not to take any action other than the specified steps below.

  1. Connect the removable storage device to your PC, type “regedit” in the Cortana Search Bar, then select the “Registry Editor” app and click on “Open.”
  2. Click on the “right-facing chevron” (angle bracket) symbol next to “HKEY_LOCAL_MACHINE” in the left sidebar to expand the directory structure of that folder.
  3. Repeat “Step 1” procedures for the “SYSTEM” folder to expand it, then do the same for “CurrentControlSet.” The complete path so far should be “HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet.”
  4. Repeat “Step 1” procedures again to expand the “Control” folder, then confirm if “StorageDevicePolicies” is present. If not, continue to “Step 5” to create it yourself. Otherwise, skip to “Step 7.”
  5. Right-click the “Control” folder. Select “New” and choose “Key.” This step will create a new subfolder under “Control.”
  6. Rename the newly created folder to “StorageDevicePolicies.”
  7. Now, right-click on “StorageDevicePolicies,” choose “New,” then select “DWORD (32-bit) Value.” Name the new entry “WriteProtect” without quotes or spaces.
  8. Double-click on “WriteProtect” and change “Value Data” to “0” and “Base” to “Hexadecimal.”
  9. Click on “OK,” exit the Registry, and restart your computer.

After the reboot, check if the USB is now operating as it should. This method disables the write protection on all your drives, so it should make your USB writable again. Beware that editing the Windows Registry on your own can mess up your computer, so after you’ve followed our instructions, it’s best not to revisit it.

If none of the above options removed file protection from your USB stick, try searching for a third-party application.

Removing USB Write Protection on a Mac

There’s much less flexibility when resolving the write protection issue on Mac versus Windows. You only have two options available—one is for storage units that can’t be written to due to a fault with the device, while the other involves formatting the drive.

Option 1: Repair the Permissions

The permissions for your USB drive might be faulty, causing it to become write-protected. If that’s the case, you should try fixing the error using “Disk Utility.” To do so, follow these simple steps:

  1. After plugging in the USB device, open “Utilities” and select “Disk Utility.”
  2. Find the drive you’d like to repair in the left sidebar and select it.
  3. Click on the “First Aid” tab, wait for any scans to finish, and then select “Repair Disk Permissions.”

If the fault was in the permission settings, the steps above should remove the USB’s write protection.

Option 2: Format the Drive

One sure way to remove the write protection on macOS is to format the drive. Beware that this process erases all data on the USB device, so ensure you copy any important files to another location before proceeding.

  1. To format the USB, launch “Disk Utility,” find the drive, then click on it.
  2. Go to the “Erase” tab, select “format,” rename the USB drive if you want to, then click on “Erase.” Confirm the action in the pop-up window to start the formatting process.

Once the drive is formatted, the write protection should be gone. When choosing a format, note that some of the options are Mac-exclusive, while others, like “exFat,” can be universally used with Mac and Windows computers.

Removing USB Write Protection on a Chromebook

If you’re using a USB with your Chromebook and suspect it’s write-protected, formatting the drive is your only option. Follow the steps below to reformat your locked USB drive or stick.

  1. Go to “Apps” and click “Files.” Alternatively, press “Alt+Shift+M” on the keyboard.
  2. “Right-click” on the drive and choose “Format Device.”
  3. Confirm the action by clicking “OK” in the pop-up prompt, then wait for the process to finish.

Unfortunately, this is the only reliable method to remove write protection from a USB on Chromebook. As previously stated, formatting the drive will erase all data, so back it up beforehand.

Remove Write Protection From a USB on Linux

If you are a Linux user, this process unlocks the write protection on your USB drive or stick.

  1. First, launch the “Applications Menu (),” then look for and click on “Terminal” or type “term” in the search bar at the top to find it and launch it. On some Linux distros, “Shift + Ctrl + T” or “Ctrl + Alt + T” launch the terminal as well.
    Linux Terminal App
  2. Next, type “lsblk” and press “enter” to get a list of all attached devices. Linux lsblk command
  3. Type “sudo hdparm -r0 /dev/sdb” without quotes and press “enter.” In this example, the USB is mounted at “/dev/sdb.” Adjust accordingly (sdb, sda, etc.) The “-r0” turns the read-only permission off. You might need to unmount/remount the USB drive via the terminal once read-only is off.Linux terminal command

In the example/procedures above, you identify the drive, then change its read-only permissions to off, then unmount and remount it via the terminal, not by ejecting it.


In closing, write protection can be a nuisance, especially when you don’t know how it happened on your storage device. Luckily, you’ve learned how to remove write protection from a USB on Windows, Mac, Linux, and Chromebook computers. The issue should no longer catch you off-guard, but there are no guarantees. With all the methods explained here, at least one should allow you to edit, copy, move, or delete files on your USB or SD card in no time!
