In Linux operating system, fsck is a useful utility that helps you to check file system integrity and fix the errors. It is helpful particularly in case of file system corruption, dirty system shutdown and operating system related issues. When improper system shutdown happens, fsck runs when you reboot the system and check file system integrity. But if fsck process gets terminated due to improper system shutdown or power failure, you might come across serious data loss issues. In such circumstances, you are required to opt for effective and powerful Linux Data Recovery solutions.

In a practical scenario where fsck process gets interrupted due to power outage, when you restart the system, all of your hard drive volumes are found to be inaccessible. It cause critical data loss situations. When you try to sort out the problem by using fdisk command on Linux hard drive, you see following message: “Warning: invalid flag 0×0000 of partition table 4 will be corrected by w(rite) Command (m for help): p Disk /dev/hdb: 203.9 GB, 203928109056 bytes 255 heads, 63 sectors/track, 24792 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System Command (m for help):”

Cause

As stated in the above error message, the problem is caused by corruption to partition table. It is an important data structure of Linux operating system that stores important information about hard drive partitions/volumes. It is a 64-byte table, which store four partition entries, 16 byte for each. Damage to the partition table means your operating system could not locate partitions on hard drive and thus can not access them. In other means, you need to carry out Data Recovery Linux for fixing this issue.

Resolution

In order to work around this issue, you need to format the hard drive and reinstall Linux operating system. It will replace the damaged partition table with new one, after that system will work perfectly. But formatting the drive would remove all the data from it and you face serious data loss situations. Linux Recovery in such situations is possible using commercial Linux Data Recovery software. The applications are completely safe and easy to use and perform absolute recovery in most of the data loss situations. Stellar Phoenix Linux Data Recovery is the most comprehensive solution for all types of data loss situations. It recovers lost data from Ext4, Ext3, Ext2 and ReiserFS file system volumes. The application is usable with all major distributions of Linux operating system.

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.

In Linux operating system, fsck (file system check) is a command-line utility that allows you to check file system and hard drive integrity. Using this tool, you can even fix some minor errors of file system. Generally, it runs automatically during system boot when Linux detects that the file system is not in consistent state, indicating improper system shutdown like power loss or system crash. However, if you run fsck tool on physical volume, you may come across some odd error messages. The errors prevent you from accessing your data and lead to data loss. At this point, you need to use Linux Data Recovery solutions to extract lost data.

When you get such error messages, experts suggest to use the ‘pacman’ utility for upgrading your Linux kernel and reboot the system for finalizing this operation.

Pacman is an application of  Linux operating system, which is used for managing other applications. This tool uses simple files in form of packages and organizes the text-based databases. This is helpful in adding, deleting, and upgrading the packages in Linux computer.

After completion of kernel up-gradation process, if you try to restart the system, system does not boot up. It may stuck on the boot screen. Despite of loading the GRUB (Grand Unified Boot Loader) and starting, the system just display “loading GRUB” message.

In such cases, if you boot the system using floppy, you may get the below error message:

“ERROR: (device hda1): XT_GETPAGE: xtree page corrupt
ERROR: (device hda1): XT_GETPAGE: xtree page corrupt”

Subsequent to above error message, if you run fsck tool, the following error occurs:

“Errors detected in Primary File/Directory Allocation Table.
File system object FF65726 linked as: /var/run/random-seed
File claims cross linked block(s).
Cannot repair FF65726.”

Cause

This problem is caused by corruption to GRUB or Linux file system. In such cases, hard drive formatting is required, which removes all the data from hard drive. To recover lost data, Data Recovery Linux is required.

You can recover lost data using Data Recovery Linux applications. These are third-party applications, which are capable of methodically scanning the entire storage media and extract lost data from it. The Linux Recovery Software have simple and self-descriptive rich graphical user interface to provide ease of use. With read-only and non-destructive conduct, the applications are safe to use.

The Linux hard drive is partitioned in various partitions/volumes for effective management of your valuable data. Linux hard drive volumes start from the boot block where boot information of the operating system is stored. Last two byes of the Linux boot block contains boot block signature. In some cases, operating system cannot locate boot block signature and the disk cannot be accessed. It makes your significant data inaccessible and leads to data loss. Such cases require you to either restore data from backup or use Linux data recovery software to scan the drive and extract data from it.

For example, you might encounter an error message similar to the following one when you attempt to boot a Linux operating system based computer-

“Master boot record on /dev/hda has been updated.”
Subsequent to the above error, you may also encounter further error message that states-
“No boot signature found on partition”

The system cannot be booted in such cases and you face severe data loss situations. To recover your business-critical data in such cases, you are required to opt for Linux recovery tools.

Grounds of the issue

This problem most frequently occurs if you overwrite the LILO (Linux Loader) boot loader with the MBR (Master Boot Record) that was primarily installed on the /dev/hda disk volume. The boot loader might be overwritten if you try to install it using -M switch. Boot block corruption also results into the same problem.
How to fix boot block corruption problem?
In order to work around this problem, you have to overwrite the Master Boot Record with Linux Loader. It is possible with the help of /sbin/lilo Linux command. This command enables the operating system to overwrite MBR information on the /dev/hdX disk. Alternatively you can use LILO on the /dev/hda2 disk as:

boot=/dev/hda2
lilo -b /dev/hda2
lilo -M /dev/hda
lilo -A /dev/hda 2

In case the above method does not work, you will have to reinstall operating system. As reinstalling the operating system removes all the data from Linux partition, you will need data recovery Linux methods to get your precious data back. Linux data recovery software employs highly-advanced Ext2 recovery algorithms to ensure absolute recovery. The advanced Ext3 recovery software are absolutely safe to use with read-only Linux recovery conduct.
