partrevive vs R-Linux

partrevive is a free, MIT-licensed utility for finding and recovering lost or deleted partition tables. It scans disks for filesystem signatures, then checks candidate filesystems through read-only loop devices and mounts to distinguish live data from ghosts. Commands cover scanning, verification, planning, file rescue, table restoration, automatic recovery, undo and disk imaging; a Tkinter interface guides users through scanning, verification, planning and restoration. The project lists NTFS, FAT12/16/32, exFAT, ext2/3/4, btrfs, XFS, F2FS and Linux swap as detected formats. It reports LVM2 and LUKS but does not rebuild them. GPT is the default restore format; MBR is available with `--mbr` and is limited to four primary partitions. Imaging uses ddrescue in two passes with a mapfile, and recovery can use a disk image. Before writing, restore and auto save the current table and check SMART health; restore prompts by default and refuses a mounted target. The single-file Python 3 program requires root and Linux system tools on PATH. The project is described as early, and fragmented or overwritten filesystems may mount incompletely.

R-Linux is a free file-recovery utility for Ext2, Ext3, and Ext4 file systems, with host versions for Linux and Windows. It can recover files after virus attacks, power failures, partition reformatting or deletion, and from disks with bad sectors. Recovery sources include hard disks, CDs, DVDs, floppy disks, Compact Flash cards, USB drives, ZIP drives, Memory Sticks, and other removable media. Memory-card recovery and file preview are supported, but RAID recovery is not. IntelligentScan can search devices with unknown file systems for known file types. R-Linux can create compressed, split, and password-protected disk or partition images, scanning while images are created; compressed images work with R-Drive Image. Bad-sector disks can be copied to an image for processing. Recovered files can be saved to any host-accessible disk, including network disks. Help documentation lists Linux mdadm and LVM/LVM2 volumes. The Linux version requires a kernel 2.6-or-newer RPM or DEB distribution, X.Org X server 1.7.6 or newer, and root privileges.
