I put a write-protected diskette into fd0
cat /dev/zero > /dev/fd0: readonly filesystem
then removed dikette, switched the plastic nibble
reinserted diskette
cat /dev/zero > /dev/fd0 : readonly filesystem
removed the diskette
cat /dev/zero: a bunch of garbage, then kernel spasms about sectors not found and
commands not performed
reinserted the diskette
cat /dev/zero > /dev/fd0: readonly filesystem
rebooted the machine
cat /dev/zero > /dev/fd0: run OK.
morale: if you are not able to write on a write-permitted diskette, reboot the kernel

Are you sure your FDD correctly recognizes media changes? Is there
anything like "kernel: VFS: Disk change detected on device fd(2,0)"
noted in your logfiles?
