Superblock is one of the most common component of metadata structure in ext2 file system. It saves critical information which is used by the file system manager to systematically manage the file system. Corruption in superblock can occur due to improper system shutdown, file system corruption, virus attack, and human errors. The system becomes unbootable once the superblock is corrupt. This further leads to inaccessibility of data saved in the hard drive. In such cases, the user needs to opt for an updated data backup to continue with his/her work. But in case, no backup is available or backup cannot restore data, then the user needs to run FSCK command or opt for an advanced Linux Data Recovery software.

To elaborate the above problem, consider a practical case where you encounter the below error message when you attempt to mount one of the hard drive volumes:

“Ide0: reset: success

hda: task_out_intr: status=0×61 {DriveReady DeviceFault Error}

hda: task_out_intr: error=0×04 {DriveStatusErrors}

Ide0: reset: success

hda: task_out_intr: status=0×61 {DriveReady DeviceFault Error}

hda: task_out_intr: error=0×04 {DriveStatusErrors}”

The above error message pops up during the mounting process and makes the data saved in the hard drive volume inaccessible.

Cause:

The root cause for the occurrence of the above mounting error message is corruption in superblock.

Resolution:

To resolve superblock corruption and to access the hard drive volume data, you will need to:

1. Run fsck -f /dev/hda8 command to repair corrupt file system.

2. If the error message persists, then find the exact corrupted superblock by running:

mke2fs -n /dev/hda8

Further, to repair it, run:

fsck -f -b 294912 /dev/hda8

3. If the problem continues, mount the hard drive partition using alternative superblock. To do so, run the command:

mount -t ex2 -o ro, sb=1179648 /dev/ hda8 /hda8

4. In case the above resolution also fails, then you will need to search for an efficient Linux Recovery application. A data recovery linux tool ensures complete recovery of data by employing advanced scanning algorithms.

Stellar Phoenix Linux Data Recovery is a powerful recovery tool that recoups missing, lost, or formatted data from any Ext2, Ext3, Ext4, and FAT based hard drive volumes. The Linux Data Recovery utility supports recovery of data from almost all kinds of hard drives like IDE, EIDE, and SATA. The tool is compatible with Ubuntu, SUSE, Red Hat, and other Linux distributions
