My university gave me a USB drive for a class, and I still have it now that the course ended. The drive is permanently write-protected, even though it has no physical lock switch. I would like to reuse it instead of throwing it away, but I cannot tell whether the restriction comes from Windows, the file system, the USB controller, or the storage itself. The device appears to contain a Micron 2450 512GB NVMe drive along with two Wilk USB 3.2 Gen 1 components. Is there a safe way to remove the write protection or repurpose the NVMe drive?

If the USB controller is genuinely locking the drive, there may not be a normal Windows setting that can undo it. Some controllers switch to permanent read-only mode after detecting problems with the flash storage. In other cases, a controller-specific recovery tool might work, but it must match the exact controller, VID/PID, and firmware. Copy any important data first, and avoid random unlock utilities because they can contain malware or erase the drive.
Try checking Disk Management first. Make sure the disk itself is not marked read-only and that the problem is not just a damaged or restricted file system. If it is a standard M.2 NVMe device, testing it with another NVMe-to-USB adapter could help determine whether the original USB controller is responsible for the lock.
If the Micron drive is a standard removable M.2 NVMe module, it may be possible to take it out of the USB assembly and test it in a separate NVMe-to-USB enclosure or directly in a compatible computer. The write protection may be enforced by the USB bridge rather than by the NVMe drive itself. It would be best to have someone experienced identify the parts before physically opening it.
