What it is
TestDisk is free, open-source software for recovering lost partitions and helping disks boot again when faulty software or human error caused the problem. It can repair partition tables, recover deleted partitions, and rebuild or restore FAT and NTFS boot sectors. Other repair tools can fix FAT tables and repair an MFT using its mirror. For file recovery, TestDisk can undelete files from FAT, exFAT, NTFS, and ext2, and copy files from deleted partitions using FAT, exFAT, NTFS, and ext2/ext3/ext4. Its listed partition recovery support also covers APFS, HFS+, XFS, and ZFS. It works with hard drives, USB drives, memory cards, disk images, DAS, SAN, and Linux RAID devices. The software is portable: users extract the package files rather than run an installer. Listed operating systems include Windows, macOS, Linux, DOS, FreeBSD, NetBSD, OpenBSD, and SunOS. TestDisk is licensed under GNU GPL v2 or later. Its maker says it does not connect to the internet or send information about the user, computer, or data. The download page lists version 7.2 dated February 22, 2024, and a 7.3-WIP beta.
