How to Fix the "Disk is Write Protected" Error on USB Drives

  

The "disk is write protected" is a common error message that most of us encounter when using a USB drive in Windows. There are a few reasons behind this issue. A USB drive itself may have a physical switch that denies read and write attributes, or if it is a bootable disk, some third-party software or Windows itself can make a USB disk write protected.

If you get the "disk is write protected" error message when attempting to format a USB disk or move/create new content to it, there is no need to worry. You can very easily fix this issue. Follow the instructions below to learn how to do it.

Before using the guide below, manually inspect whether your USB disk has a physical switch to enable/disable write protection. If it does not have a switch, follow the instructions below.

Resolving USB Write Protection Issues in Windows 11/10

1. First, insert your USB disk into your Windows 11/10 PC.

2. Now, open Command Prompt as Administrator, type diskpart and press Enter.

3. Next, type list disk and press Enter. It will list all the disks (like Disk 0, Disk 1, Disk 2) connected to your PC. Identify your problematic disk.

4. If your disk is Disk 2, type select disk 2 and press Enter.

5. Now, type attributes disk clear readonly and press Enter.

If it is a bootable disk, after step 4, follow the instructions below.

6. Now, type clean and press Enter (it will erase everything on the drive).

7. Next, type create partition primary and press Enter (it will create a new partition (storage area) on your USB drive).

8. Type format fs=ntfs quick or format fs=fat32 quick and press Enter.

9. Next, type assign and press Enter (this makes your USB drive appear in File Explorer).

10. Finally, type exit and press Enter to close the Command Prompt.

The write protection message should no longer appear. 

Advanced users can alternatively use a registry method to resolve this issue. Since you will be editing the Windows Registry, create a backup and proceed with caution.
