Atleast once in life, most of us do wrong with the important data on our computer and then we think we must not have deleted this, whether some important documents or lectures' videos or bunch of important projects. Instead of cursing yourselves for such a foolish mistake, let's do some work. Let's try to recover that deleted data out from our HD. Here I am reviewing 5 of the best Data recover tools that can help recovering deleted data on Linux.
What Is Data Recovery ?
Data recovery is the process of rescuing and handling the data from damaged, failed, corrupted, or inaccessible secondary storage media when it cannot be accessed normally. Often the data are being salvaged from storage media such as internal or external hard disk drives, SSD, USB flash drive, CDs, DVDs, RAID and other electronics. Recovery may be required due to physical damage to the storage device or logical damage to the file system that prevents it from being mounted by the host operating system (OS).
The most common reason for data recovery is the failure of operating system. When system fails to boot then we need to save or recover important data.
5 Best Data Recovery Tools For Linux
If we are using Linux and we need to recover data due to any of the reason whether physical damage or logical damage, we have many tools for this purpose of recovering data. To not to confuse with many, here I am reviewing 5 of the best data recovery tools for Linux. This article will help you choosing the one that you need without going through bunch of data recovery tools for Linux.
SystemRescueCD is based on Gentoo Linux and can be used as a bootable CD-ROM or USB drive for repairing unbootable or otherwise damaged computer systems after a system crash.

3. Avira Rescue System
Avira Rescue System is a set of free tools that include a utility used to write a bootable CD which can be downloaded as an ISO file. It has its own Linux-based operating system so it does not depend on the one on the host PC. It can be used to clean an unbootable PC, and is able to find malware. The tool contains the antivirus program and the virus database current as of the time of download. It boots the machine into the antivirus program, then scans for and removes malware, also restoring normal boot and operation. It is updated frequently so that the most recent security updates are always available.
Avira Rescue System is basically a bootable antivirus programs that scans system for viruses but it also fixes unbootable or damaged system.

2. Trinity Rescue Kit
Trinity Rescue Kit (TRK) is a free and open-source Linux distribution with a command-line interface. TRK was designed for deployment as a live CD or live USB. The author of TRK, Tom Kerremans, includes in the distribution various third-party software utilities for repairing damaged files, recovering data, resetting passwords, detecting computer viruses, and disk cloning. TRK is especially equipped for repairing common problems in Microsoft Windows and Unix-like operating systems.
To reduce disk space required, TRK uses a bespoke help command, trkhelp, instead of the man pages typical of Linux distributions.
Preview build 396 was released in March 2014. A fork of TRK called Mango (MAssive Network GhOst) was released by Juan Carlos Pineda, modified to simplify cloning computers.
TRK 3.3 was based on Linux 2.6.26.

Knoppix is the best and most used recovery tools or Linux distribution for fixing a broken system.
Knoppix is an operating system based on Debian designed to be run directly from a CD / DVD (Live CD) or a Live USB, one of the first of its kind for any operating system. Knoppix was developed by 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 of Knoppix: the traditional Compact Disc (700 megabytes) edition and the DVD (4.7 gigabytes) "Maxi" edition. Each of these main editions have two language-specific editions: English and German.
Knoppix mostly consists of free and open source software, but also includes some proprietary software, so long as it fulfils certain conditions.
Knoppix can be used to copy files easily from hard drives with inaccessible operating systems. To quickly and more safely use Linux software, the Live CD can be used instead of installing another OS.
Content Included In Knoppix
More than 1000 software packages are included on the CD edition and more than 2600 are included on the DVD edition. Up to 9 gigabytes can be stored on the DVD in compressed form. These packages include:
