Fix USB Drive Becoming Write Protected Error on Windows 7 Ultimate

When inserting my USB drive into my desktop PC running Windows 7 Ultimate, it becomes write-protected. And when I use it on my laptop, I can't delete the files. I have tried scanning for malware and viruses, but it did not work. Can I repair this error without reformatting it? Can anyone help me?

For the question you mentioned above, my answer is, "Yes, you can repair this error without reformatting the USB drive." According to your description, your USB drive is under the state of write protection, which means that you cannot modify or delete any file on your desktop PC running Windows 7 Ultimate or laptop. Therefore, according to my own experience, you need to remove your USB drive from write protection, and then you can freely delete or modify the files on your USB drive.

The first method is to check the physical switch of your USB drive. You should check whether there is such a physical switch on your USB drive and if it is in write protection mode. If your USB drive is ON, you need to turn it ON to OFF on your USB drive.
