I have some 5.25 inch diskettes that do not have a 'write protect'
notch in them, yet i can still write to them in certain drives. The
jackets of these diskettes are a pale blue color, and partially
transparent (if you hold them against a strong light source you can
see the outline of the internal magnetic medium). If i put a sticky
tab on the disk where the notch would be, this cuts down the light
transmission enough to make the disk 'unwritable'. Most confusing!
