xxHash is an extremely fast non-cryptographic hash algorithm. It works at speeds close to RAM limits, and comes in both 32- and 64-bit flavours. The code is highly portable, and hashes of the same length are identical on all platforms (both big and little endian).

GNU Parted is a package for creating and manipulating disk partition tables. It includes a library and command-line utility.

This package provides a library for manipulating storage volume encryption keys and storing them separately from volumes to handle forgotten passphrases.

Gpart tries to guess the partitions on a PC-style, MBR-partitioned disk after they have been inadvertently deleted or the primary partition table at sector 0 damaged. In both cases, the contents of these partitions still exist on the disk but the operating system cannot access them.

Gpart ignores the partition table and scans each sector of the device or image file for several known file system and partition types. Only partitions which have been formatted in some way can be recognized. Several file system guessing modules are built in; more can be written and loaded at run time.

The guessed table can be restored manually, for example with fdisk, written to a file, or---if you firmly believe it's entirely correct---directly to disk.

It should be stressed that gpart does a very heuristic job. It can easily be right in its guesswork but it can also be terribly wrong. Never believe its output without any plausibility checks.

This package provides a user-extensible heap manager built on top of jemalloc which enables control of memory characteristics and a partitioning of the heap between kinds of memory (for NUMA).

GNU ddrescue is a fully automated data recovery tool. It copies data from one file to another, working to rescue data in case of read errors. The program also includes a tool for manipulating its log files, which are used to recover data more efficiently by only reading the necessary blocks.

nwipe securely erases disks using a variety of methods to ensure the data cannot be recovered. It can wipe multiple drives in parallel and can be used noninteractively or with a text-based user interface.

libblockdev is a C library supporting GObject introspection for manipulation of block devices. It has a plugin-based architecture where each technology (like LVM, Btrfs, MD RAID, Swap...) is implemented in a separate plugin, possibly with multiple implementations (e.g. using LVM CLI or the new LVM D-Bus API).

lf (as in "list files") is a terminal file manager written in Go. It is heavily inspired by ranger with some missing and extra features. Some of the missing features are deliberately omitted since they are better handled by external tools.

This package provides a partial implementation of iSNS, specified by RFC4171. It's an maintained fork of https://github.com/cleech/open-isns.

GParted is a GNOME partition editor for creating, reorganizing, and deleting disk partitions. It uses libparted from the parted project to detect and manipulate partition tables. Optional file system tools permit managing file systems not included in libparted.

rmlint finds space waste and other broken things on your file system and offers to remove it. rmlint can find:

• duplicate files and duplicate directories,

• non-stripped binaries (i.e. binaries with debug symbols),

• broken symbolic links,

• empty files and directories,

• files with broken user and/or group ID.

XFE (X File Explorer) is a file manager for X. It is based on the popular but discontinued, X Win Commander. It aims to be the file manager of choice for all light thinking Unix addicts!

QDirStat is a graphical application to show where your disk space has gone and to help you to clean it up.

GPT fdisk (aka gdisk) is a text-mode partitioning tool that works on Globally Unique Identifier (GUID) Partition Table (GPT) disks, rather than on the older Master Boot Record (MBR) partition scheme.

Wipe can erase files and block devices securely. To work properly it relies on several assumptions like having the block device write the correct sectors, etc. For files it also doesn't work on log-structured file systems such as F2FS, JFFS, LogFS, etc. You should not trust wipe to work as advertised until you have manually verified that all its assumption hold true on your system. To overwrite data it uses the Mersenne Twister pseudo-random number generator (PRNG) that is seeded with /dev/urandom or, if unavailable, /dev/random.

This package provides a tool to resize FAT partitions using libparted.

This software supports RAID device discovery, RAID set activation, creation, removal, rebuild and display of properties for ATARAID/DDF1 metadata.

dmraid uses libdevmapper and the device-mapper kernel runtime to create devices with respective mappings for the ATARAID sets discovered.

udevil is a command line program that mounts and unmounts removable devices without a password, shows device info, and monitors device changes. It can also mount ISO files, NFS, SMB, FTP, SSH and WebDAV URLs, and tmpfs/ramfs filesystems.

This package provides a statically-linked fsck.fat and a fsck.vfat compatibility symlink for use in an initrd.

GNU fdisk provides a GNU version of the common disk partitioning tool fdisk. fdisk is used for the creation and manipulation of disk partition tables, and it understands a variety of different formats.

ranger is a console file manager with Vi key bindings. It provides a minimalistic and nice curses interface with a view on the directory hierarchy. It ships with rifle, a file launcher that is good at automatically finding out which program to use for what file type.

Idle3-tools provides a utility to get, set, or disable the Idle3 timer present in many Western Digital hard drives. This timer is part of the "IntelliPark" feature that stops the disk when not in use. Unfortunately, the default timer setting is not well suited to Linux or other *nix systems, and can dramatically shorten the lifespan of the drive if left unchecked.

TestDisk is primarily designed to help recover lost partitions and/or make non-booting disks bootable again when these symptoms were caused by faulty software or human error (such as accidentally deleting a partition table). TestDisk can:

1. Fix partition table, recover deleted partition

2. Recover FAT32 boot sector from its backup

3. Rebuild FAT12/FAT16/FAT32 boot sector

4. Fix FAT tables

5. Rebuild NTFS boot sector

6. Recover NTFS boot sector from its backup

7. Fix MFT using MFT mirror

8. Locate ext2/ext3/ext4 Backup SuperBlock

9. Un-delete files from FAT, exFAT, NTFS and ext2 file systems

10. Copy files from deleted FAT, exFAT, NTFS and ext2/ext3/ext4 partitions.

This package also includes the photorec command, described below.

PhotoRec is file data recovery software designed to recover lost files including video, documents and archives from hard disks, CD-ROMs, and lost pictures (thus the Photo Recovery name) from digital camera memory. PhotoRec ignores the file system and goes after the underlying data, so it will still work even if your media's file system has been severely damaged or reformatted. It can recover lost files from at least:

1. FAT

2. NTFS

3. exFAT

4. ext2/ext3/ext4 file system

5. HFS+
