How to recover lost and corrupted data from Linux system

Lambert Butler Updated On - 29 Jan 2019

Linux is one of the popular and widely-used computer operating system. It is an open source operating system and its underlying source codes can be modified and redistributed in both commercial and non-commercial applications. Many times, some errors within its script occur and it further leads to lose of your important data. There may be different situations, in which you may lose your crucial data from Linux system. Below mentioned reasons are some of the mostly encountered ones:

  • Intentional or accidental deletion of data from the Linux system.
  • Corruption of file system.
  • Malfunctioning of operating system.
  • Infection of virus/malware.
  • Corruption of storage media.
  • Hardware/Software malfunctioning.

Master Boot Record (MBR) is the partition sector of a partitioned hard disk. It holds the primary partition table of the hard disk. LINUX system boots when the BIOS pass the execution of the machine code in the MBR. Thus, any problem with the MBR directly affects the booting process of the hard disk, making it inaccessible. Such situations are very irritating and require LINUX data recovery techniques to get back your valuable data. These cases are a sure possibility in case of the dual boot systems; however, due to human errors, viruses, power fluctuation or any hardware/software malfunction can lead to MBR corruption.

Typical Linux data issues result following errors:

  • Device Boot Start End Blocks Id System.
  • Partition 1 does not end on cylinder boundary.
  • Partition 2 does not end on cylinder boundary.
  • Partition table entries are not in disk order”
  • Error – Mount wrong fs type. Bad option. Bad super block on /dev/hdb2.
  • Error – Operation not supported on transport endpoint.
  • Grub Error 17 – Cannot mount selected partition.
  • Grub Error 12 – Invalid device requested.

These are just a few examples of number of error messages encountered by you while dealing with a loss of or corruption with your Linux data. To trouble-shoot such errors, you can use some techniques in safe mode and the first step is to run the “fsck” command. It can help you in finding and fixing a Linux data corruption but it must be run in “single user” mode.

In case of a MBR damage or corruption, you can tackle situation with below mentioned options:

  • Replace the MBR with a Disk Editor.
  • Replace the MBR with the Recovery Console.

With the help of above techniques, you can resolve your minor LINUX data lose situations. But, in case of severe data lose or data corruption issues, you fail to troubleshoot data lose situations. If you are suffering from such situations then don’t get worried because now it’s easily possible. You just need to use a professional third party tool like Kernel for Linux Data Recovery tool. It is much powerful to help you for recovering all possible data from Linux system.
