I don't think there ever were such drives. There were some that had the

Is the usual disk/CD power connector 4pin or 5? Sorry, do not have this at
sightseeing distance, only remember that it has +-5V and +-12V (and maybe
ground too?)

4 pins: +5v, +12v, ground, plus the 4th pin which is also sometimes
ground (but may sometimes be unconnected, I think - at least one of my
USB external power connectors is IIRC)
