When attempting to use a USB device, have you ever discovered that you failed to add or modify files? It happens as a result of write protection. A USB drive with write protection serves as a shield, prohibiting you from changing the data stored, adding new files, or removing old ones. 

Sometimes, you might want this protection to keep your data extra safe by making the drive read-only. While meant for security, this can be incredibly frustrating when you need to modify your files or urgently transfer new data to the flash drive.

How to Add Write Protection to USB? 5 Ways Recommended 

Ready to remove that extra layer of annoying read-only permission to your USB drive? If you are looking for an easy solution to know how to enable write protection on USB, this guide is for you. It will help you learn five ways to enable write protection on a USB drive. 

Now let's get going! Please note that some of these techniques may require specific permissions, and others may need formatting a drive that will remove all files from the flash drive. Here are five ways to achieve write protection:

  • USB Write-Protection Software: It's the most efficient and simple solution, especially for novice Windows users.
  • Diskpart: An integrated Windows utility that provides fine-grained management (advised users should approach with caution).
  • Windows Registry: For those who are accustomed to modifying registry entries.
  • Properties: Directly altering the drive's permissions
  • Turn On BitLocker: Windows feature that provides a layer of write protection to your encrypted drive.

Please note that USB write-protected software provides a streamlined experience for those who are not tech-savvy Windows users. The other methods require more caution, especially Diskpart, as a single error could potentially damage your data.

FAQs on Adding Write Protection to USB

Let's address some common questions about enabling and resolving write protection issues on your USB drive.
