TestDisk

TestDisk is free, open‑source data recovery software from CGSecurity, designed to help you recover lost partitions and make non‑booting disks bootable again due to faulty software, certain viruses, or human error—such as accidentally deleting a partition table.

What it does

• Repairs partition tables and recovers deleted partitions
• Fixes boot sectors (FAT, NTFS) to restore bootability
• Restores access when the file system or partition layout is damaged

How it works

Partition recovery with TestDisk is straightforward: select the disk, choose the partition table type (Intel/MBR, GPT), and let TestDisk analyze and search for lost or damaged structures. Review the results and write the corrected layout when you are confident.

When to use TestDisk vs PhotoRec

Use TestDisk for repairing partition tables, recovering deleted partitions, fixing boot sectors, and restoring access when the file system layout is damaged. Use PhotoRec for signature‑based file carving after severe file‑system loss.
