I've yet to see one of these Samsung drives that

they made dozens, if not hundreds of different revisions/models of these
drives.
I've shipped several to customers with old CNC gear that use the PC98
convention of pin 34 = READY, pin 2 = DISK CHANGED and pin 4 = IN USE.
You need a couple of cm of wire for the pin 2 disk change, but the mod
is very obvious.
The 720K thing hasn't come up yet, as all of the drives that I've sent
out have been for PC98-style controllers which don't use 2D media, so I
haven't bothered to check. In fact, I don't know if the sensor's
optical or mechanical. In either case, the remedy is obvious.
