The new SanDisk Ultra USB 3.0 I purchased has write protection. I attempted to alter it via the command prompt (attributes disk clean read-only), but the problem has not been resolved. I tried to change it through regedit. But still, the issue is not solved. Can you tell me how I can fix this problem?
If the write protection occurs on a USB drive, it's often due to storage firmware detecting issues, such as unsafely unplugging the device. Despite trying CMD and regedit, you may still be experiencing the problem. Don't worry, as two reliable solutions are available to help resolve this issue.
