How to Fix USB Is Write Protected or Read Only, Help

The write-protected or read-only error shows up when I plug my USB into my computer. I can't transfer data to it, nor can I modify or delete any files already stored on it. I am unable to reformat the drive using Windows Disk Management, DiskPart, GParted, or other tools. The drive does not have a write-protect switch. Why did this happen, and what can I do about it?

Suppose the write-protected or read-only error message shows on your PC when you plug in the USB. In that case, you can only read the information but not change or delete any data on this drive. Some reasons might lead to this problem:

  • Filesystem corruption.
  • Incorrect group policy settings.
  • Power problem on the USB used to read the drive.

I will share some worked and tested methods to help you handle this. However, before fixing this problem, ensure your USB is not out of space.
