In 2372, the Drovana participated in the Klingon Empire's covert mining of the Bajoran system. The Drovana was severely damaged when a cloaked mine accidentally detonated ten kilometers off its port quarter, causing a massive hull breach and betraying the Klingons' presence.
The USS Defiant towed the crippled warship back to Deep Space 9 for repairs. While docked at DS9, Commander Worf and Kurn stowed aboard the Drovana and accessed its computer in order to uncover the mine strategy and deployment. (DS9: "Sons of Mogh")
