In Linux operating system, the superblock stores important information about the files, folders, inode tables, block group size, disk block map and file system. Corruption in superblock primarily occurs due to file system damage, metadata structure malfunctioning, software bugs and more. Two major consequences of the corrupted superblock are unbootable system and inaccessible data. In such situations, you need to restore the data from the latest backup. However, in case of absence of an updated backup, you need to use powerful Linux Data Recovery software.As a practical scenario, you moved all your music files to a Linux volume. When you attempt to boot your Linux hard drive, you encounter the below error message:Couldn't find valid filesystem superblockdumpe2fs: Attempt to read block from filesystem resulted in a short read while trying to open /dev/hdd1Running FSCK -f on /dev/hdd gives another error message:Couldn't find ext2 superblock, trying backup blocks...fsck.ext3: Bad magic number in super-block while trying to open /dev/hddAll the music files become inaccessible after the occurrence of above error message. Cause:The above error message primarily occurs because of superblock corruption.

To systematically recover and restore data from formatted Linux hard drive volume, you need to opt for powerful Linux Recovery software.Such Linux Recovery tools do complete scan and recovery of the affected volume by incorporating effective scanning methods. These recovery utilities recover and restore data a fter issues like superblock corruption, group descriptors faults and inode table damage. With highly graphical documentation, these tools are self-explanatory without any prior technical knowledge. They serve as user-friendly utilities due to their largely automated recovery procedures and simple graphical screens.Stellar Phoenix Linux Data Recovery is the foremost Linux Recovery application.
