The first fast format routine I've seen in the old days was the "speeddos plus" one that was a very popular 1541/C64 hardware mod in Italy since 1984 (if memory works). I think the speeddos plus modification originated in Germany.. I seem to remember that it would just write each track without reading back the sectors but I may be very well wrong after all these years. I still have two speeddos plus systems, one is my original C64 and one is an SX-64 donated from a local friend. Both were modified around mid 1985.
