[Star Trek] What would happen if the drive section of a starship was destroyed but the saucer section survived?

Would the drive section be rebuilt or would they scrap the whole thing and start from scratch?

Really depends on the nature of the damage.  If the saucer section had separated prior to the destruction of the drive section and had gotten far enough away to remain relatively undamaged, sure - it'll be refurbished and mated with another drive section -  the Federation is post scarcity but they've also kept the Miranda class hull in service for over 100 years - they're practical.
