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.

Sdparm reads and modifies SCSI device parameters. These devices can be SCSI disks, in which case the role of sdparm is similar to its namesake: the hdparm utility originally designed for ATA disks. However, sdparm can be used to access parameters on any device that uses a SCSI command set. Such devices include CD/DVD drives (irrespective of transport), SCSI and ATAPI tape drives, and SCSI enclosures. This utility can also send commands associated with starting and stopping the media, loading and unloading removable media and some other housekeeping functions.

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).

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

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 dosfstools package includes the mkfs.fat and fsck.fat utilities, which respectively make and check MS-DOS FAT file systems.

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

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

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.

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.

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+

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

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

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.

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 simple theme for SDDM, black background with Guix's logo. Based on Arch linux's archlinux-simplyblack theme.

Chili reduces all the clutter and leaves you with a clean, easy to use, login interface with a modern yet classy touch.

SLiM is a Desktop-independent graphical login manager for X11, derived from Login.app. It aims to be light and simple, although completely configurable through themes and an option file; is suitable for machines on which remote login functionalities are not needed.

Features included: PNG and XFT support for alpha transparency and antialiased fonts, External themes support, Configurable runtime options: X server -- login / shutdown / reboot commands, Single (GDM-like) or double (XDM-like) input control, Can load predefined user at startup, Configurable welcome / shutdown messages, Random theme selection.

SDDM is a display manager for X11 and Wayland aiming to be fast, simple and beautiful. SDDM is themeable and puts no restrictions on the user interface design. It uses QtQuick which gives the designer the ability to create smooth, animated user interfaces.
