Consider a scenario wherein you are working on a Linux system that has live ext3 file system. You run the fsck utility and find the following error message:

“EXT3-fs: corrupt root Inode, run e2fsck”

If you run e2fsck on the same volume after getting the aforementioned error message, then the following error message is displayed:

“Root Inode is not a directory. Clear?”

Select either “Yes” or “No” when you get this error message. If you select “Yes”, then the parent entry of each Inode in the root directory is removed and the following message is displayed:

“Missing ‘..’ in directory Inode”

Now, you need to find the root cause of the problem.

Cause:
The root cause of the corruption in the file system is that you have used the fsck utility on the mounted Linux system. Once this happens, the system is unable to boot and the data becomes inaccessible.

Resolution
To resolve this issue, you should replace the existing file system. For this, you would need to format the existing system and reinstall Linux system. However, in that case you will not be able to retrieve valuable data. So, to repair the file system and to recover trapped data you need to use a third-party Linux recovery software to perform data recovery of Linux system. These tools are highly interactive and read-only in nature.

Stellar Phoenix Linux Data Recovery is a Linux recovery tool that enables you to recover lost, formatted, and deleted data from the Linux systems. It is capable of performing ext2 recovery, ext3 recovery, and ext4 recovery. This Linux data recovery tool supports various Linux distributions such as Red Hat, SUSE, Debian, Caldera, Mandrake, Sorcerer, TurboLinux, Slackware, Gentoo, etc. It is compatible with Windows 7, Vista, Server 2003, XP, and 2000.

Consider a practical scenario, where you encounter the below error message when you attempt to boot your system:

“Uncompressing Linux:…Ok booting kernel

audit(xxx.x….x..:0) : initialized

EXT3-fs error (device hda3):ext3_check_descriptors:Block bitmap for grade 38 not int grade ( block 34799616)

EXt3-fs:roup descriptors corrupted.

Mount: error 22 mounting ext3

pivot root ivot_root (/sysroot, /sysroot/initrd) failed: 2

unmount/initrd/proc_failed:2

kernel panic: No init found: Try passing init=0 to kernel”

You encounter the same error message each time you attempt to boot your system. As a result of the above error, all your critical data becomes inaccessible.

Cause:

The above error message is encountered when group descriptors are corrupted.

Resolution:

To resolve the above issue and access the data, you need to use FSCK command. This command is mainly used to repair the EXT3 file system. But, if the file system has been badly corrupted, then this command fails to repair. In such circumstances, you need to recreate the file system again by formatting and reinstalling Linux. A clean reinstall of Linux will completely erase all data from the selected Linux volume. For complete and orderly recovery of data after reinstalling Linux, you will need to se powerful Linux Recovery software.

These Linux Data Recovery applications ensure comprehensive scanning of formatted Linux volumes by using powerful scanning algorithms. These recovery tools can recover and restore data after problems like group descriptors faults, Inode table damage and superblock corruption. They are built with highly graphical and interactive user interface that makes them easily understandable without prior technical skills.

Stellar Phoenix  Linux Data Recovery is the most efficient and trust worthy Linux Recovery tool. It supports Ext2, Ext3 and ReiserFS file systems based Linux volumes. This read only Data Recovery Linux application gets installed on Windows (Vista, XP, 2003 and 2000) and the affected Linux drive should be connected as slave.

The amount of information that becomes available each year is incredible, growing in leaps as technology evolves. Hosting all that information isn’t an easy task, as there are a lot of things that can happen, including being deleted, lost, corrupted, inaccessible or formatted.

If that data is important to you, then you can have a big problem. The next step would probably be to look for a software that you can use to recover your lost data. You can use the data recovery process for that purpose. There are data recovery options both for Linux and Windows.

You can use Linux data recover software to get your information back, in a number of different cases:

- You lost folders or files on Linux

- Your hard drive was formatted

- Your operating system was corrupted or it crashed

- A lost or deleted volume

You might be wondering by now what the Linux data recovery software can do.

It’s capable of doing a number of types of recovery process.

- Ex3 and Ex2 Data Recovery

- Recovery of a Linux Partition

- Recovery of a Linux Formatted Disk

- ReiserFS File System Recovery

- Recovery of Linux Deleted Files

The Linux data recovery software can do all the things I mentioned above. The strong algorithm behind this software will find all the corrupted, formatted, lost, deleted or inaccessible folders and files.

After it finds those files, the software repairs them and you can use them again. In the end, the files that were recovered will be put in the same place where they were before, so you can use them again.

If you keep getting error messages, you might have some problems with corrupted files on your Linux based computer. Some of the possible error messages are:

1. Unknown terminal type Linux and similar

2. Cannot read the table of mounted file systems

3. Cannot initialize drive X and many more.

4. Maximum count Reached

5. Internal Compiler Error

If you get one of the messages mentioned here, start the Linux data recovery software and try getting your files back. Download or buy the program, install it and start it.

Due to an improper shutdown, your system may not be able to boot and you might experience some error messages. The error message may sound like the followings:

“Your system appears to have shut down uncleanly
Press Y within 4 seconds to force file system integrity check”
According to the above error message, when you press Y, you may receive another error message stating:

“Checking root filesystem
[/sbin/fsck.ext2 (1) -- /] fsck.ext2 – a /
WARNING: couldn’t open /etc/fstat: no such file or directory
ext2fs_check_if_mount/

PROBLEM
Due to incapability the super block could not read or does not describe a correct ext2 file system.  If the device is authentic and it really contains an ext2 file system, then the super block is corrupt, and you might try running e2fsck with an alternate super block: e2fsck -b 8193 :
No such file or directory while determining whether / is mounted.
fsck.ext2: Is a directory while trying to open /
/etc/rc.d/rc.sysinit: line 415: failure: command not found.”

After highlighting the above errors, the system does not boot and one cannot access his precious data from hard drive and thus may face the problem of data loss.

REASON
This happens to Linux operating system due to severely corrupted root file system. Due to this problem, the operating system cannot find the required files to boot and thus shows you the error messages.
In Linux operating system, the root file system is the file system which is used to manage data on the root partition, the partition is the one on which operating system is installed. The Root file system retains very significant files and any kind of corruption in these files brings the need of Linux Data Recovery.

SOLUTION
The Linux Data Recovery is the process of retrieving the missing or inaccessible data from Linux hard drive. This can be done in the best possible way by using Linux Recovery Software. This software is able to scan your hard drive, locate the lost data and then perform Linux Recovery.
Stellar Phoenix Linux Data Recovery software is the best ever made and the most comprehensive Linux Recovery Software. It is efficient enough to thoroughly scan your hard drive and retrieve all of your data from it. One of most attracting features of Phoenix Linux Data Recovery is that it is compatible with most of the Linux flavors.
