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.

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.

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.

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 parted bindings for Python.

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

mmc-utils is a command-line tool for configuring and inspecting MMC storage devices from userspace.

Gdu is a disk usage analyzer written in Go. It is intended primarily for SSD disks where it can fully utilize parallel processing, but it also works on HDDs.

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.

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).

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.

This package provides a utility library for managing the libnvdimm (non-volatile memory device) sub-system in the Linux kernel.

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.

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.

findimagedupes compares a list of files for visual similarity.

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.

hddtemp is a small utility that gives you the temperature of your hard drive by reading S.M.A.R.T. information (for drives that support this feature).

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.

The Open iSCSI project is a high-performance, transport independent, multi-platform implementation of RFC3720 iSCSI.

Features:

• highly optimized and very small-footprint data path

• persistent configuration database

• SendTargets discovery

• provides CHAP support

• PDU header Digest

• multiple sessions

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.

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.

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

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