The moment you realize files are missing, disconnect the SSD. Writing any new data to the drive can overwrite the deleted files and destroy them forever.
Searching for modified versions of software labeled with "Crack" or hosted on third-party file-sharing sites often leads to serious security vulnerabilities.
If the data lost is of extreme financial or sentimental value and the SSD is physically damaged or not mounting, skip software entirely and send the drive to a physical data recovery lab.
