Partitions created in the hard drive enable you to install different operating systems. A partition table is positioned at the first sector (cylinder 0, head 0 and sector 1, Master Boot Record) of every hard drive. This table contains the information about locations and sizes on the hard drive. Corruption in a partition table can occur due to improper system shutdown, file system corruption, software bugs and more. Once the partition table is corrupted, the user may not be able to boot a particular operating system. Furthermore, the data saved in the unbootable partition becomes inaccessible. In such situations, you need to restore the data from the latest backup. To recover the data completely, in case of no backup availability, you need to use effective Linux Data Recovery application. To perform dual boot on the computer system, the user installs two operating systems (Windows Vista and Linux). The user encounters the below error message when he attempts to boot the Lin ux operating syste:Partition table invalid or corrupt This is not goodHowever, when the user attempts to start Windows Vista operating system, he can easily do so. The above error message mainly appears when the sanity checks on the integrity of the partition table fail. After the above error message appears, the data saved in that particular hard drive partition (where Linux is installed) becomes inaccessible. Resolution:To resolve the above error and access the partition data, you need to check the partition table by running FDISK command in Linux. You need to make sure that the at least one of the partitions has been marked as active. However, if there is more than one partition marked as active, then you need to remove that active flag from either of those partitions. If the above measure fails to perform and the user is still not able to access the partition data, then he needs to reinstall Linux on that partition. Reinstalling Linux will delete all the previously saved data from the hard drive partition. To recover the lost data, the user needs to use powerful Linux Recovery software. Such Data Recovery Linux applications employ advanced and high-end scanning methods to recover the lost data. With interactive user-interface, these utilities are easy to understand. A world-wide trusted, effective and advanced application that fulfills all the requirements of being the finest Linux Recovery application is Stellar Phoenix Linux Data Recovery.

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. Resolution:To troubleshoot and resolve the above problem, you will need to take these steps: Run the Linux Rescue CD and try to boot the system. Now you need to type fdisk l to list all disks and volumes. Boot the system by using an alternate superblock. However, if the above solutions fall short of resolving the above problem, you should reinstall Linux operating system. In such situations, all the data from your hard drive volume gets erased. 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. It is compatible with Ext2, Ext3 and ReiserFS file system based Linux volumes. This read only Data Recovery Linux utility gets installed on Windows (Vista, XP, 2003 and 2000) and the affected Linux drive is connected as slave.

In Linux and UNIX operating systems, daemon is the computer program that runs in the background other than direct control of a user. You can use these daemons to configure your hardware (like devfsd) and perform tasks like scheduled run of cron in your Linux system. But sometimes, these programs fail to start while booting the Linux system. It can occur due to certain inconsistencies or corruption issues in the file system. In such situations, you need to use a recent and valid data backup to restore the data. However, if the data backup fails to provide the required results, efficient Linux Data Recovery applications can be used to recover the lost files. Consider a scenario, you try to boot Linux system and daemons fail to start. Additionally, when you reboot the system, you get a GRUB error message. When you use the boot disk to mount your root partition, it fails. CauseAs described above, if root partitions file system suffers corruption, the daemons may fail to start at bootup. It can occur if any of the metadata structures like superblock, inode etc. is damaged due to user errors like unexpected system shutdown, incorrect use of commands and more. Solution You can follow these steps to solve this issue: You can run the fsck command to diagnose and repair file system issues of hard disks root partition. The fsck is a command-line utility that can fix various issues of file system corruption. If you find errors that fsck cant fix and still observe the same issues, you need to reformat the hard disk and restore the lost data from a recent data backup. A format operation erases all the data from the selected Linux partition or volume. But, if you do not have a valid data backup, you need to scan your hard disk using Linux Recovery software to recover the lost or inaccessible files. Linux Data Recovery applications are specially designed to scan drives affected from logical data loss. These software can locate the missing information and t hen safely restore it. You will find such Data Recovery Linux tools with user-friendly interface plus remarkably fine recovery capabilities. Stellar Phoenix Linux Data Recovery is an effective Linux Recovery solution. The application supports Ext2, Ext3 and ReiserFS file systems. It is compatible with most of the Linux distributions like RedHat, TurboLinux, Slackware etc. It gets installed on Windows (Windows Vista, XP, 2003 and 2000) and the affected Linux hard drive should be connected as slave.

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.
