TestDisk
Free, open-source partition and boot recovery from CGSecurity. Recover lost partitions and make non-booting disks bootable again.
What is TestDisk?
TestDisk is free, open-source data recovery software from CGSecurity. It was designed to help you recover lost partitions and make non-booting disks bootable again when the cause is faulty software, certain viruses, or human error—such as accidentally deleting a partition table.
It is a powerful partition and data recovery utility that works at the file-system and partition-table level. Partition table recovery with TestDisk is straightforward: select the disk, choose the partition table type, and let TestDisk analyze and search for lost or damaged structures.
Best used for
- Repairing partition tables
- Recovering deleted partitions
- Fixing boot sectors (FAT, NTFS)
- Restoring access to drives where the file system or partition layout has been damaged
TestDisk is not for signature-based file carving after severe file-system loss—for that, use PhotoRec, the companion tool. Both are distributed together by CGSecurity.
