It's not possible to override it at a software level. It's possible the
onboard write-protect circuitry failed, as I believe I may have had a
drive with this problem before myself.
That was literally, the ONLY occasion that the drive
in question ever
pulled that trick, so I doubt anything was "broken" on the drive, just
that it malfunctioned the one time.
Odd.
that). My other (and more plausable theory) is that my
write protect
sticker had enough play in it, that a physical switch sensor might
have been right on the verge of writeable (although, I don't know if
those drives used a finger as a sensor, or a light beam, or how far a
finger has to pass thru the disk to see it as writable)
Disk ]['s used a mechanical switch for the write protect sensor. I'm not
sure about the later Apple 5.25" Drives. So your theory about play in the
write protect sticker is plausible.
