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

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.

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.

This package provides parted bindings for Python.

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.

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.

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.

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!

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.

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

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

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).

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.

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).

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

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.

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+

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

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 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.

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.

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.
