Like other computer operating systems, Linux also comprise of various components, which include Superblock. Superblock is a significant metadata of the Linux operating system, which describes file systems on the Linux hard drive. The system components have interdependency and work together to keep your system functional. However, if any of these system components or data structures gets damaged, the system may not work properly and you can not access stored data from the hard drive. This behavior leads to critical data loss situations and require Linux Data Recovery to be fixed.

Under some situations, you can not mount your Linux file system and the data stored on the Linux hard drive volumes can not be accessed. Most of the problem occurs in a dual-boot system. When you try repairing your Linux file system on the root partition, process could not complete successfully. It renders your entire system inaccessible.

When you run fsck utility on the affected Linux hard drive, without 'L' option, you may come across the below error message:

"Leonzwei root # xfs_repair -nLv /dev/hdc3
Phase 1 - find and verify super block...
Bad primary super block - bad magic number!!!
Attempting to find secondary super block...
Found candidate secondary super block...
error reading super block 54 - seek to offset 57982058496 failed
unable to verify super block, continuing"

The repair process is interrupted after the above error message. In such cases, you need to identify the cause of this behavior and then perform Data Recovery Linux by resolving it.

Grounds of the problem

This behavior takes place because of corruption to the Linux Superblock. File system can not mount after Superblock corruption and thus your system can not boot up. Corruption may occur due to numerous reasons, such as virus infection, improper system shutdown, user errors, and more.


You can sort out this problem by replacing the damaged Superblock with its identical copy, which is maintained by Linux operating system to prevent such problems. However, if it is not possible, hard drive formatting is the only way to go. It actually removes all the data from hard drive and causes severe data loss. At this point, you need to use Linux Recovery applications to get your mission critical data back. The applications are particularly designed to methodically scan entire hard drive and extract all lost data from it, ensure absolute Linux Data Recovery.

Stellar Phoenix Linux Data Recovery is the most advanced and effective utility to ensure perfect recovery in all data loss situations. The software works well with all major distributions of Linux operating system, including Red Hat, SUSE, Fedora, and Debian. It Recover Linux from Ext4, Ext3, Ext2, FAT32, FAT16, and FAT12 file system volumes.
