In Linux operating system, you can check the integrity of file system and hard drive. This command resolves majority of issues with hard drive and file system, avoiding need of Linux Data Recovery. This command-line utility runs in five phases. In first phase, it checks data blocks and their size, in second phase, it checks for path names. In the following phases, connectivity, references counts, and the cylinder groups are examined respectively. If the fsck fails in second phase, situations can be very drastic.
The fsck may fail in the second phase due to iNode issues. In a practical scenario, you may come across the below error message while checking integrity and consistency of your system through fsck utility:
-Root inode is not a directory. Clear?-
After this error message, you can not access your Linux hard drive and encounter serious data loss situations. In order to gain access of your valuable data in such circumstances, you need to find out the cause of this problem and perform Data recovery linux by sorting it out.
Grounds of the issue:
This problem occurs after corruption to the root iNode. The corruption might be caused by improper system shutdown, virus infection, system crash, and more.
In Linux file system, iNode is a data structure that holds all the critical information of files and directories, except their names and contents. It is a unique number, assigned to every file/directory. Every file/directory has an individual iNode. The file/directory is accessed through iNode only.
In the particular situation, the root iNode of Linux system is damaged. It is generally the second iNode. Root iNode is first iNode to file system and it represents starting point or root of file system.
If you select ‘Yes’ in above error message, it will remove parent entry of every iNode from root directory. In third phase of the fsck utility, root iNode is tried to recover, but you encounter further error if the process fails:
-Cannot Allocate Root Inode-
In such critical situations, Linux Data Recovery is required to extract lost data. The recovery is best possible using Linux Recovery software, which perform absolute recovery in the majority of data loss situations. With read-only conduct and simple graphical user interface, the applications are completely safe and easy to use.
Stellar Phoenix Linux Data Recovery is the most advanced application to recover lost, missing, and inaccessible Linux data. It recovers from Ext4, Ext3, Ext2, FAT12, FAT16, and FAT32. The software is designed for all distributions of Linux operating system including SUSE, Debian, Red Hat, and Fedora.
