Restored disk picture, get well earlier information? : linux

Hiya, I not too long ago restored a disk picture on an exterior SSD. The difficulty is, I solely wished to revive the picture of a single partition, not your complete disk. A careless mistake. I’ve a sense it is doable to get well the misplaced information, and figured that is the most effective place to ask for recommendation. How, if doable, can I get well the information? Thanks
