Linux Data Loss Due to GRUB Corruption - Computers - Data Recovery

When you run fsck on your Linux file system's physical volume, sometimes you may encounter certain error messages. These error messages prevent you from accessing data from a particular volume. In such situations, technical experts recommend to use 'pacman' tool to upgrade the kernel and reboot your system to complete the operation. Pacman is a Linux tool that is used to manage the applications. It uses simple files in package format and organizes text-based package database. It is useful in adding, removing and upgrading packages in Linux system. After updating the kernel, when you attempt to reboot the system, sometimes your system may get stuck during the boot process. In place of loading GRUB (Grand Unified Boot loader) and booting, your system just tries to process the required information, showing "loading GRUB" message. In such situations, when you try to boot your system using floppy disk, you may encounter the following error message:"ERROR: (device hda1): X_GETPA GE: xtree page corrupt ERROR: (device hda1): XT_GETPAGE: xtree page corrupt"After this behavior, when you again run fsck, you encounter the following error message:"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."Subsequent execution of fsck also detects several errors but fails to fix them.CauseThis problem generally occurs due to corrupted GRUB or file system of your Linux system. In both of these situations, to carry out Linux Recovery, you need to format your hard drive and install fresh copy of both these data structures. Formatting may delete all of your stored data from hard drive and you need to go for third party Linux Recovery tools to get Linux Recovery done. These tools are very powerful and are able to perform Data Recovery Linux i all situations of data loss.Stellar Information Systems Limited, the leading data recovery company globall y, provides Stellar Phoenix Linux Data Recovery. It is the finest and most promising Linux Recovery software. It supportsLinux Data Recovery from Ext2, Ext3 and ReiserFS file system based volumes. Phoenix Linux Recovery is compatible with most of Linux distributions.

Interruption To File System Writing Process Cause Linux Data Loss - Computers - Data Recovery

In a Linux computer, the file system is metadata that is used for organizing and managing data that is stored on the hard drive. The file system ensures integrity of data. Along with storing data files, the file system also holds and manages important information about files, directories and file system itself (such as date and time stamp, access permission, ownership, file size, storage location and so forth). Since the file system attempts to work as asynchronous as possible, for avoiding the hard drive bottleneck, any interruption of this process may result into severe data loss. For example, consider this case: What happens when your Linux computer crashes while working on a large file that is stored on a Linux file system based hard drive? There may be various options:If the machine crashes after saving the file, you do not lose anything. Just restart your computer and you should be able to access it normally. If the machine crashes before you save the file, you lose all your changes to the file but the data that was already in it remains intact. If the computer crashes while writing data to the hard drive, the file becomes totally unusable. Your application can not open this file and thus you can not access the data. If the machine crashes while your drive is writing to the metadata areas like the directory itself, your file system gets corrupted and you lose all your data on that particular drive volume. To fix such scenarios Linux provides an inbuilt utility, known as fsck. It checks the file system integrity and can fix it in several cases. But this tool is not helpful in case of large file systems. It requires considerable time to perform the check on larger Linux volumes. In such situations, it becomes extremely significant to perform Linux Data Recovery to get your data back. It is the process of retrieving lost data and can easily be performed using powerful linux recovery softwae such as Stellar Phoenix Linux Data Recovery. Phoe nix Data Recovery Linux is a commanding tool that ensures efficient Linux Data Recovery in the majority of data loss situations. It supports Linux Recovery from Ext2, Ext3 and ReiserFS file system volumes. Thislinux data recovery tool is compatible with SUSE, Red Hat, Kubuntu and several other Linux distributions.

How to avoid Linux Data Loss Situations - Computers - Data Recovery

Though Linux is among the safest and the most reliable computer operating systems that are available today and it is designed to provide high stability, but data might also get lost from Linux systems. Data loss is an unforeseen situation that may cause damage to valuable files and settings on any platform.The Linux data loss generally occurs as a result of user mistakes, but it could also occur due to system issues like file system corruption, operating system failure, disk failures and more. To avoid these situations, it is a good idea to make extra copy of your important and sensitive data. In Linux, you can use the following methods to backup your data and prevent data loss:Archiving with tar: In this process you need to collect the data that you want to backup and then compress it. This process includes concatenating all the list files and removing unnecessary blank spaces. It is done using tar command that can be used to backup data on any storage device. Incremental backup with tar: Tar command allows you to create incremental backup with N parameter. Using this parameter, you can give a date and tar command would check the modification time of all the files against this date. If the files are modified more recently than the given date, they would be included in backup. Compressing with Gzip: You can compress and backup your important Linux data using the Gzip tool. It would add suffix.gz to file name and delete the original file. You can uncompress these files using d option. Though all these methods are good to backup your data and avoid data loss situations, but the archives made with proprietary tar version may be incompatible with another version on another system. It may prevent you from recovering your data from tar files and require Data Recovery Linux to handle the situation. Linux Data Recovery is best possible using powerful Linux Recovery software such as Stellar Phoenix Linux Data Recovery. It is designed to perform Linux Recovery from Ext2, Ext3 and ReiserFS file system volumes. Phoenix Data Recovery Linux tool can perform easy, effective and safe Linux Recovery from Red Hat, Debian, SUSE, Kubuntu and several other Linux distributions.
