TestDisk is a free, open-source utility for recovering lost partitions and helping disks boot again when faulty software or human error is responsible. It can repair partition tables, restore or rebuild FAT and NTFS boot sectors, fix FAT tables, and repair an MFT using its mirror. File tools can undelete files from FAT, exFAT, NTFS, and ext2, or copy files from deleted partitions using those formats and ext3/ext4. Listed recovery formats also include APFS, HFS+, XFS, and ZFS. It works with hard drives, USB drives, memory cards, disk images, DAS, SAN, and Linux RAID devices. TestDisk runs on Windows, macOS, Linux, DOS, FreeBSD, NetBSD, OpenBSD, and SunOS. The download is portable: extract its files rather than running an installer. Its features are described for novices and experts, including gathering drive information for a technician and onsite recovery work. The maker says it does not connect to the internet or send user, computer, or data information.
