‘fsck’ or the ‘file system check’ is a system utility that checks the consistency of the file system in LINUX and all UNIX like operating systems. Once, the system detects any inconsistency in it, following any unsystematic system shut down, this tool runs automatically at the booting process. The fsck tool facilitates repairing of the file system as specified by the user or else, it can do the on its own automatically. However, sometimes, fsck also fails to fix certain errors and the data in your LINUX drive become inaccessible thereafter. In such cases, you need to look for any LINUX data recovery utility to recover back your valuable data.
Usually, in case of an odd shut down of the LINUX system following any power surge or power failure, the process of read or write is interrupted all of a sudden and hence, there happens a corruption to the directory block that stores the information about the data. The fsck locates such inconstancy with flashing error messages, following which the system even fails to boot-up. The error messages shown by fsck are as follows:
It seems to have fatal corruptions. Running with
–rebuild-tree is required.
*ev/sda1: clean 33/522240 files, 80815/1044193 blocks [fail]
* fsck failed. Please repair manually.
All the error messages point towards a single thing that there is a serious corruption to the file system and may be due to the same, the operating system is not able to access the boot sector of the computer.
Whatever be the data loss situation, it is important to recover the data from the drive first. Hence, once fsck fails to repair the corruption and the data remains inaccessible, the best option is to restore your data from the backup. However, if backup is not available or failed to restore the data from the backup server, try running any LINUX data recovery software.
LINUX data recovery software are designed to recover and restore the lost or inaccessible data from any LINUX based drive irrespective of the data loss situation. These applications provide rich graphical user interface and stepwise instruction set, which facilitate a smooth recovery experience to the users.
