About TestDisk for Mac
TestDisk is a powerful, free and open-source data recovery utility from CGSecurity. It is designed to recover lost partitions and make non-booting disks bootable again — problems often caused by accidental deletion, faulty software or a damaged partition table.
TestDisk analyzes the disk structure, finds partitions that disappeared, and can write a repaired partition table back to the drive. It can also rebuild boot sectors and undelete files on several file systems.
Because TestDisk can change disk structures, read each step carefully and, if possible, back up or clone the affected drive first. For recovering individual photos and documents, its companion tool PhotoRec is often the better choice.
