Cannot remove write protection from USB drive

The disks are dead and they never worked. Their working for a short time was only an optical illusion.

If you look in the messages in the Event Viewer, the device is identified as
Device USBSTOR\Disk&Ven_&Prod_USB_DISK_3.0...

Notice that there is no Vendor ID or useful Product ID, meaning that the firmware on the disk is even incapable of identifying itself. This by itself is not unknown with cheap disks, but it only adds to the general air of cheap fakery.

If there is any way of returning these disks and getting reimbursed, don't hesitate. Better avoid this vendor in the future.
