Like every other operating system, Linux computer also contains a system or boot volume, which is used to boot your system. Boot device is one on which all the boot files and Linux operating system are installed. In some cases, you may encounter boot errors while trying to start Linux-based computer. This behavior may occur due to missing or damaged boot files. In such cases, Linux system refuses to boot and you can not access the data stored on your Linux hard drive. It leads to critical data loss and needs Linux Data Recovery.

When you try to boot your Linux computer, you may receive the following warning message:

“EXT2-fs warning: mounting unchecked fs, running e2fsck is recommended”

After the above error, when you run ‘e2fsck’ utility, you face further error messages that resemble the followings:

•    TivoMaster:/var/tmp$ e2fsck -y /dev/hda7 e2fsck 1.06, 7-Oct-96 for EXT2 FS 0.5b, 95/08/09 e2fsck: Bad magic number in super-block while trying to open /dev/hda7

•    The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock:

e2fsck -b 8193 <device>

This behavior of Linux operating system renders all your data inaccessible. In order to access your valuable data, you need to identify the cause of this problem and perform Data Recovery Linux by resolving the problem.

Root of the problem

This problem may occur after improper system shutdown without unmounting the root file system. After this, the root file system may get damaged and you will face the above stated problem.

Resolution

You can sort out this problem by formatting the hard drive and reinstalling Linux operating system. After formatting, you need to restore data from the current backup as it removes all the data from hard drive. However, if the backup is not available, Linux Recovery becomes essential.

Recovery is possible using advanced tools, known as Linux Data Recovery software. These software are designed to scan damaged hard drive using powerful algorithms and extract data that can not be accessed normally. They perform absolute recovery in a safe and easy way.

Stellar Phoenix Linux Data Recovery is the most effective tool that insures perfect recovery in all cases of data loss. The software is developed to recover data from Ext4, Ext2, Ext2, FAT32, FAT16, and FAT12 file system volumes. It works well with all major distributions of Linux operating system, include Debian, Mandriva, SUSE, Red Hat, Fedora, and Ubuntu.

Linux is a popular open source operating system, which offers great security features. You can install Linux operating system on a system that is already using Windows operating system, by making it dual-boot. The dual-boot configuration allows you to use features of both operating system. The boot loader enables you to select any of these operating system to boot from. However, in some situations, this behavior may cause damage to the Linux volume. This behavior leads to critical data loss and you need to use Linux Data Recovery to get your precious data back.

In a dual-boot system, you can access data from your Linux hard drive, even if you have used Windows operating system to boot the computer. To access data, you need to mount the Linux volume. But in some situations, when you attempt to access the Linux volume by mounting it, the process can not complete and you encounter any of the below error messages:

“can’t find ext2 File System on dev ide1 (22, 65)”

Or

“mount: wrong file system type, bad option, bad superblock, or too many mounted file systems”

When these errors occur, you can not access data from the Linux hard drive partitions. If you try to boot the system using Linux operating system, it stops responding with some boot errors. It causes data loss and need Data Recovery Linux to get your valuable data back.

Cause

The issue occurs due to corrupted or missing Ext2 file system of your Linux volume. The file system or Linux hard drive volume may get damaged due to numerous reasons such as virus infection, power surges, improper system shutdown, operating system malfunction, and improper mounting of the hard drive.

Resolution

You can sort out this problem by restoring lost data from the most recent backup. Backup is the most excellent solution to prevent data loss situations. However, if you do not have backup or its not updated, Linux Recovery is required to handle the situation.

The recovery is best possible with the help of third-party Ext2 Recovery applications. The tools use powerful scanning algorithms for in-depth scanning of the hard drive and extracting lost data from it. You can easily recover lost data using these programs even if you do not have prior technical skills as they have simple graphical user interface.

Stellar Phoenix Linux Data Recovery is a read-only and advanced application to recover all types of lost data. The software recovers data from Ext4, Ext3, Ext2, FAT32, and FAT16 file system volumes. It is compatible with all popular distributions of Linux including Red Hat, SUSE, Fedora, Debian, and Mandriva.

Are you resizing your Linux hard drive partitions using Gparted utility? Create an absolute backup of your valuable data before your proceed. Gparted provides you advanced and easy methods to perform a number of operations on your Linux volumes. However, in some cases, re-sizing the partition with Gparted utility can become very problematic. It may corrupt the volumes and cause critical data loss situations. In order to recover lost data in such circumstances, Linux Data Recovery becomes need of hour.

Gparted is an inbuilt tool in Linux operating system, which enables you to create, resize, deleted, copy, move, or check hard drive partitions, and file systems on partitions. It also creates partition table on hard drive and enables/disables the partition flags like hidden and boot. It is helpful for reorganizing disk usage, creating space for new OS, mirroring one volume with another, and copying the data stored on hard drive.

Sometimes, while resizing the Linux hard drive partitions through Gparted tool, the process may gets terminated with read/write errors. After this alarming incident, hard drive doesn’t mount at all and gives you further errors.

At this point, if you run the fsck utility after restarting the problem remains intact. Furthermore, you encounter further error messages. The situations keep getting more and more serious at every attempt of solving this problem. Linux superblock may get damaged, and give you the indication of file system corruption.

The problem can be indicated by various error messages, such as:

“Superblock corrupted, run with -b 32768″

Some warning messages may also occur, which indicates the the device is busy and it cannot be accessed.

Redundant copies of the superblock are maintained by Linux file system. You can fix this issue by using any of such copies. You can search alternative superblock using “mkfs -n” command.

However, if you cannot find a superblock that is free from corruption, you need to format the hard drive and reinstall operating system. Although, this method can fix up the problem, but also removes all the data from hard drive and creates need of Data Recovery Linux.

You can recover Linux data with the help of third-party Linux Data Recovery software. The applications enable you to perform Linux Recovery on your own as they have simple graphical user interface.

Stellar Phoenix Linux Data Recovery is the most advanced and widely used application to perform absolute recovery of lost Linux data. It works well with all major distributions of Linux operating system, such as Red Hat, Debian, SUSE, Fedora, and Ubuntu. The software recovers lost data from Ext4, Ext3, Ext2, FAT32, VFAT, FAT16, and FAT12 file system volumes.

In Linux operating system, the file system stores all critical information about files located on hard drive. Without file system, operating system can not located and access data from the hard drive as the operating system accesses file system pointer to locate data. Thus, for proper working of your system, the file system should remain free from corruption or any other problems. In the else case, you come across data loss situations and you need to go for Linux Data Recovery to extract data from the drive.

In a practical scenario, while dealing with Ext2 file system of Linux operating system, you may come across below error message:

“EXT2-fs error (device 09:00): ext2_check_descriptors: Block bitmap fo

not in group (block 3670099)!

EXT2-fs: group descriptors corrupted”

After this error message, you can not access data from the drive and your system may possibly can not boot up. In order to fix this issue, you have to find out the its cause and perform Data Recovery Linux by fixing it.

Root of the problem

The Ext2 file system is made of several Block Groups that create block group descriptor, which is responsible for controlling and managing files creation and file access operations. This metadata structure has Block Bitmap, Inode Bitmap, Inode Table, and Super Block like information that are most critical components of Linux file system.

The above error occurs due to corruption to Block Bitmap that works as a map of all the blocks in group. When you run fsck in such situations, you get further error messages that states severe file system corruption and superblock corruption.

Resolution

There are two possible fixes of this problem:

1) Locate and run fsck with alternative metadata structures.

2)Format the hard drive and reinstall operating system to replace damaged file system with new one.

Although, second option is able to sort out all such issues, but also has a downside. It removes all the data from hard drive and cause catastrophic data loss. In such cases, Ext2 Recovery applications are required to handle the situation.

The Linux Data Recovery software are particularly designed to scan the drive using powerful scanning algorithms and extract all lost data from it. They enable you to perform Linux recovery on you own as of rich graphical user interface. The tools preserve integrity of your data due to read-only and non-destructive behavior.

Stellar Phoenix Linux Data Recovery is a robust utility for assured recovery of lost data. The softwre recovers data from Ext4, Ext3, Ext2, FAT32, FAT16, and FAT12 file system volumes. It works well with all major distributions of Linux operating system including Red Hat, SUSE, Debian, and Fedora.

Like other computer operating systems, Linux also indicates system problems in the form of error messages. The problems may occur at startup or while working on your system. In some error messages, the actual cause of the problem and possible solution is provided. However, some errors do not contain any suggestions. They just include some codes.

The error messages generally occur due to problems with system data structures, system files, and other resources, which make your system and data inaccessible. This behavior leads to significant data loss from your Linux hard drive and requires Data Recovery Linux to be sorted out.

In a practical scenario, you may come across the below error message while working on your Linux machine:

“Make Says, Error 139″

After the above error, Linux system does not work properly and shuts down. The problem occurs every time when you boot your system or perform a specific set of operations. This error renders your system inaccessible and causes serious data loss. In order to get your business-critical data recovered, identify the cause of this problem and perform Linux Data Recovery by resolving it.

Root of the problem

This error occurs when your compiler dumps the core. You have a damaged, old, or buggy version of the GCC (GNU Compiler Collection). The compiler corruption may occur due to numerous reasons, such as unexpected system shutdown, operating system malfunction, virus infection, file system corruption, and more.

You may also face this situations due to problems with the disk or memory corruption. The disk corruption is resulted when metadata structure of the hard drive become faulty. In such cases, operating system can not locate and access data from the hard drive.

Resolution

Go through any of the below steps to sort out this issue:

•    Install latest release of Linux compiler or EGCS (Experimental/Enhanced GNU Compiler System).

•    Check wait states, clock rate, and the refresh timing for SIMMS and cache. Use fsck command-line utility to scan the disk and fix errors.

•    Use powerful and advanced third-party Linux Recovery software to recover lost, missing, deleted, and inaccessible data from Linux hard drive.

Linux Data Recovery tools employ high-end scanning techniques to methodically scan whole hard drive and extract all data from it. With simple user interface and read-only behavior, they perform easy and safe recovery in all cases of data loss.

Stellar Phoenix Linux Data Recovery software recovers lost data from Linux hard drive, USB drive, and network mapped drive. The software works well with all major distributions of Linux operating system, including Red Hat, SUSE, Debian, Ubuntu, and Mandriva. It supports recovery from Ext4, Ext3, Ext2, FAT32, FAT16, and FAT12 file system volumes.

In Linux operating system, you can re-size the hard drive volumes with preservation of your critical data stored on the volume, using Gparted utility. It can also be used for creating, moving and removing hard drive volumes. In some situations, resizing the hard drive volume might cause serious problems of data loss. Unsuccessful operation of disk resizing might render the disk volumes and stored data inaccessible. In these cases, you are required to opt for effective and powerful Linux Data Recovery software to get all of the missing, lost and inaccessible data. In a practical scenario, when you resize the hard drive volumes using Gparted utility in Linux, read/write operation may halt it and the hard drive might not mount.

When you try to access data from the affected hard drive, you come across a number of error messages. In such situations, if you run fsck command to detect and repair errors, it does not detect any problem and you encounter further error messages. The error message can be similar to the following one: At this point, your Linux system does not boot up and thus you can not access the stored data form hard drive. In these circumstances, you need to find out the cause of this issue and go for Data Recovery Linux to retrieve lost data.

Cause of this problem

This issue generally occurs due to corruption to the Superblock. It is one of the most critical database of your Linux operating system. The above error message indicates that your file system is severely damaged and thus the system can not work.

Resolution

The Linux operating system keeps redundant copies of superblock. You can use any of them to sort out the problem. You can search alternative superblock using ‘mkfs -n’ command. If you are unable to replace damaged superblock or the problem is with file system, you can go for hard drive formatting and operating system reinstallation. The process will replace all the damaged system resources and install a clean file system. Though above process can resolve the current problem, but it also has a drawback. Formatting the hard drive removes all of the data from it and cause critical data loss situations.

In these cases, you require Linux Data Recovery to handle the situation. Recovery is best possible using third part Linux Recovery software. The applications use high-end scanning techniques to thoroughly scan the affected drive and retrieve all of the lost, missing and inaccessible data. They are quite easy and safe to use. Stellar Phoenix Linux Data Recovery is the most excellent solution for all your Linux data loss problems. It supports recovery from Ext4, Ext3, Ext2 and ReiserFS file system volumes. The software is compatible with all major Linux distributions including RedHat, Fedora, Debian and Ubuntu.
