Gpart
gpart is a software utility which scans a storage device, examining the data in order to detect partitions which may exist but are absent from the disk's partition tables. Gpart was written by Michail Brzitwa of Germany. The release on the author's website is now older than the releases some distributions are using. It appears that Michail Brzitwa does not actively maintain the code, instead the various distributions (I.E. Fedora or Debian) appear to maintain their own versions. gpart tries to guess partitions from any device that can be partitioned, even a file. If the primary partition table has been lost, overwritten or destroyed the partitions still exist on the media but the operating system cannot access them. gpart ignores the primary partition table and scans the disk (or disk image file) sector after sector for several filesystem/partition types. It does so by "asking" filesystem recognition modules if they think a given sequence of sectors resembles the begin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gparted
GParted (acronym of GNOME Partition Editor) is a GTK front-end to GNU Parted and an official GNOME partition-editing application (alongside Disks). GParted is used for creating, deleting, resizing, moving, checking, and copying disk partitions and their file systems. This is useful for creating space for new operating systems, reorganizing disk usage, copying data residing on hard disks, and mirroring one partition with another (disk imaging). It can also be used to format a USB drive. Background GParted uses libparted to detect and manipulate devices and partition tables while several (optional) file system tools provide support for file systems not included in libparted. These optional packages will be detected at runtime and do not require a rebuild of GParted. GParted supports the following filesystems: Ext2, Ext3, FAT16, FAT32, HFS, HFS+, JFS, Linux-swap, ReiserFS, Reiser4, UFS, XFS, and NTFS. GParted is written in C++ and uses gtkmm to interface with GTK. The gene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cfdisk
cfdisk is a Linux partition editor, similar to fdisk, but with a different, curses-based user interface. It is part of the util-linux package of Linux utility programs. The current cfdisk implementation utilizes the libfdisk library note the " #include "Retrieved on 18 March 2020 and supports partitioning of disks, that use Master boot record, , , SGI or ...

Sfdisk
sfdisk is a Linux partition editor. In contrast to fdisk and cfdisk, sfdisk is not interactive. All three programs are written in C and are part of the util-linux package of Linux utility programs. Since sfdisk is command-driven instead of menu-driven, i.e., it reads input from standard input or from a file, it is generally used for partitioning drives from scripts or used by programs, like e.g. KDE Partition Manager. The current sfdisk implementation uses the libfdisk library. sfdisk supports MBR (DOS), GPT, SUN and SGI disk labels, but it no longer provides any functionality for CHS (Cylinder-Head-Sector) addressing since version 2.26.

Knoppix
KNOPPIX ( ) is an operating system based on Debian designed to be run directly from a CD / DVD (Live CD) or a USB flash drive (Live USB), one of the first live operating system distributions (just after Yggdrasil Linux). Knoppix was developed by, and named after, Linux consultant Klaus Knopper. When starting a program, it is loaded from the removable medium and decompressed into a RAM drive. The decompression is transparent and on-the-fly. Although KNOPPIX is primarily designed to be used as a Live CD, it can also be installed on a hard disk like a typical operating system. Computers that support booting from USB devices can load KNOPPIX from a live USB flash drive or memory card. There are two main editions: the traditional compact-disc (700 megabytes) edition and the DVD (4.7 gigabytes) "Maxi" edition. The CD edition had not been updated since June 2013 until recently. As of version 9.1, CD images are being released once again. Each main edition has two language-specific edi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TestDisk
TestDisk is a free and open-source data recovery utility that helps users recover lost partitions or repair corrupted filesystems. TestDisk can collect detailed information about a corrupted drive, which can then be sent to a technician for further analysis. TestDisk supports DOS, Microsoft Windows (i.e. NT 4.0, 2000, XP, Server 2003, Server 2008, Vista, Windows 7, Windows 8.1, Windows 10), Linux, FreeBSD, NetBSD, OpenBSD, SunOS, and MacOS. TestDisk handles non-partitioned and partitioned media. In particular, it recognizes the GUID Partition Table (GPT), Apple partition map, PC/Intel BIOS partition tables, Sun Solaris slice and Xbox fixed partitioning scheme. TestDisk uses a command line user interface. TestDisk can recover deleted files with 97% accuracy. Features TestDisk can recover deleted partitions, rebuild partition tables or rewrite the master boot record (MBR). Partition recovery TestDisk retrieves the LBA size and CHS geometry of attached data storage devices (i.e. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Journaling File System
A journaling file system is a file system that keeps track of changes not yet committed to the file system's main part by recording the goal of such changes in a data structure known as a "journal", which is usually a circular log. In the event of a system crash or power failure, such file systems can be brought back online more quickly with a lower likelihood of becoming corrupted. Depending on the actual implementation, a journaling file system may only keep track of stored metadata, resulting in improved performance at the expense of increased possibility for data corruption. Alternatively, a journaling file system may track both stored data and related metadata, while some implementations allow selectable behavior in this regard. History In 1990 IBM introduced JFS in AIX 3.1 as one of the first UNIX commercial filesystems that implemented journaling. The next year the idea was popularized in a widely cited paper on log-structured file systems. This was subsequently i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FAT32
File Allocation Table (FAT) is a file system developed for personal computers. Originally developed in 1977 for use on floppy disks, it was adapted for use on hard disks and other devices. It is often supported for compatibility reasons by current operating systems for personal computers and many mobile devices and embedded systems, allowing interchange of data between disparate systems. The increase in disk drives capacity required three major variants: FAT12, FAT16 and FAT32. The FAT standard has also been expanded in other ways while generally preserving backward compatibility with existing software. FAT is no longer the default file system for Microsoft Windows computers. FAT file systems are still commonly found on floppy disks, flash and other solid-state memory cards and modules (including USB flash drives), as well as many portable and embedded devices. FAT is the standard file system for digital cameras per the DCF specification. Overview Concepts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mount (Unix)
In computing, mount is a command in various operating systems. Before a user can access a file on a Unix-like machine, the file system on the device which contains the file needs to be mounted with the mount command. Frequently mount is used for SD card, USB storage, DVD and other removable storage devices. The command is also available in the EFI shell. Overview The mount command instructs the operating system that a file system is ready to use, and associates it with a particular point in the overall file system hierarchy (its ''mount point'') and sets options relating to its access. Mounting makes file systems, files, directories, devices and special files available for use and available to the user. Its counterpart umount instructs the operating system that the file system should be disassociated from its mount point, making it no longer accessible and may be removed from the computer. It is important to umount a device before removing it since changes to files may have only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Backup
In information technology, a backup, or data backup is a copy of computer data taken and stored elsewhere so that it may be used to restore the original after a data loss event. The verb form, referring to the process of doing so, is "back up", whereas the noun and adjective form is " backup". Backups can be used to recover data after its loss from data deletion or corruption, or to recover data from an earlier time. Backups provide a simple form of disaster recovery; however not all backup systems are able to reconstitute a computer system or other complex configuration such as a computer cluster, active directory server, or database server. A backup system contains at least one copy of all data considered worth saving. The data storage requirements can be large. An information repository model may be used to provide structure to this storage. There are different types of data storage devices used for copying backups of data that is already in secondary storage onto archive fi ...
