When I want to format my flash drive, it prompts an error message 'The disk is write-protected.' It has no switch, and I guess it's a virus. So I tried using Malwarebytes and Avast, but it is still write-protected. So I removed it manually using a CMD, but I can't hit the delete key. There is no delete option in the window. I also tried the Storage Device Policies in the registry, but it is already set to '0'. Any suggestions?
If your flash drive is write-protected, you can neither disable the write protection nor format it. In that case, you can only read the information but not change or delete any data on this drive. Sometimes one single file is write-protected could lead to this error. So, it would be best if you made sure the read-only option is unchecked:
Many write protection removal tools also exist if you want to avoid fixing this manually. I highly recommend using Qiling Disk Master Free to remove the write protection of your flash drive. It has enhanced features like Partition Manager, Disk Clone, and Disk Converter.
Remove the write protection and format the drive as follows:
Step 1. Launch the Qiling Disk Master Free on your computer.
Step 2. Select the "Toolkit" section from the left navigation bar.
Step 3. Click "Write Protection," select the protected device, and hit the "Disable" button.
Step 4. Open the "Partition Manager" section, right-click, and choose the "Format" option.
