R-Studio

R-Studio is a data recovery suite from R-Tools Technology built for both home users and data recovery professionals. It recovers files from deleted, formatted, or damaged partitions across NTFS, FAT/exFAT, HFS+/APFS, Ext2/3/4, and UFS file systems, and can reconstruct virtual RAID arrays when a controller fails or an array configuration is lost. Beyond local disks, R-Studio can recover data from remote machines over a LAN or the internet, and ships with an Emergency bootable version that runs from a USB stick when Windows itself will not start. A free demo mode lets users scan a drive and preview recoverable files before paying for a license.

TestDisk

TestDisk is a free, open-source data recovery utility that fixes partition tables and recovers lost partitions when problems stem from software faults, viruses, or user error. It can rebuild damaged or deleted partitions for FAT, NTFS, exFAT, and other filesystems, repair boot sectors, fix FAT tables, and rebuild the NTFS Master File Table using its mirror copy. It also undeletes individual files from FAT, exFAT, NTFS, and ext2 filesystems and ships bundled with PhotoRec, a companion tool for recovering lost photos, videos, and documents. TestDisk runs from a text-based menu interface on DOS, Windows, Linux, macOS, and several BSD variants, and is licensed under the GPL.
