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.

Duc maintains a database of accumulated sizes of directories of the file system, and allows you to query this database with some tools, or create fancy graphs showing you where your bytes are.

Duc comes with console utilities, ncurses and X11 user interfaces and a CGI wrapper for disk usage querying and visualisation.

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.

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.

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

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.

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

This package contains user-space utilities to create and inspect bcache partitions. It's rather minimal as bcache is designed to work well without configuration on any system.

Linux's bcache lets one or more fast block devices, such as flash-based SSDs, to act as a cache for one or more slower (and inexpensive) devices, such as hard disk drives or redundant storage arrays. In fact, bcache intends to be a superior alternative to battery-backed RAID controllers.

Bcache is designed around the performance characteristics of SSDs and tries to minimize write inflation. It's file-system agnostic and does both write-through and write-back caching.

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.

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.

hdparm is a command-line utility to control ATA controllers and disk drives. It can increase performance and/or reliability by careful tuning of hardware settings like power and acoustic management, DMA modes, and caching. It can also display detailed device information, or be used as a simple performance benchmarking tool.

hdparm provides a command line interface to various Linux kernel interfaces provided by the SATA/ATA/SAS libata subsystem, and the older IDE driver subsystem. Many external USB drive enclosures with SCSI-ATA Command Translation (SAT) are also supported.

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

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

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

Duperemove is a simple tool for finding duplicated extents and submitting them for deduplication. When given a list of files it will hash their contents on a block by block basis and compare those hashes to each other, finding and categorizing blocks that match each other. When given the -d option, duperemove will submit those extents for deduplication using the Linux kernel extent-same ioctl.

Duperemove can store the hashes it computes in a hash file. If given an existing hash file, duperemove will only compute hashes for those files which have changed since the last run. Thus you can run duperemove repeatedly on your data as it changes, without having to re-checksum unchanged data.

Duperemove can also take input from the fdupes program.

This package provides the host tools for controlling a Greaseweazle: an Open Source USB device capable of reading and writing raw data on nearly any type of floppy disk

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.

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.

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+

fff (fast file-manager) is a simple, blazing fast and minimal file manager for Linux, written in bash. It only requires bash and coreutils, and its highly optimized now for efficient performance.

F3 (Fight Flash Fraud or Fight Fake Flash) tests the full capacity of a flash card (flash drive, flash disk, pendrive). F3 writes to the card and then checks if can read it. It will assure you haven't been sold a card with a smaller capacity than stated.

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.

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.

All-singing, all-dancing, fully colourised df clone written in Python. It displays the amount of disk space available on the mounted file systems, using different colours for different types of file systems. Output format is completely customizable.
