I had the same problem.  The little mechanical arm was bent and was not
pushed down far enough to trip the sensor.  Some tape/paper to build up a
bulge on your disks near the write protect hole would help in the short term.
For the long term you will need some simple mechanical work on your drives,
easiest might be some epoxy to build up the tip of the trip arm.

Some drives have a sensor that directly passes light, some have a mechanical
arm that then leads to the actual sensor.  (probably an optical sensor in
either case)
