In Linux operating system, you should arrange to mount root file system as read-only to start with at boot time. If required then remount the file system in read/write mode. Most of the Linux distributions follow this process. If your operating system does not do this, you must read the documentation and then find out how to set your file system to follow this process.

You are required to specify -n option to mount the file system so that it does not try to update the /etc/mtab directory, otherwise the file system will fail and you will not be able to access data from it. It might cause data loss in some situations and require Linux Data Recovery to be sorted out. When a file system failure occurs on Linux file system, you generally encounters following error messages, which may stop the functionality of your system:

“EXT2-fs warning: maximal count reached.” This error message is caused by Linux operating system kernel when it mounts the file system, which is marked as clean but the number of mounts since check has reached predefined value. It might sometimes cause file system corruption and put you in need of Data Recovery Linux. The possible solution to resolve this problem is to install latest version of ext2fs utilities. You can check maximum number of counts by using tune2fs utility. “Cannot read table of mounted file systems.” You encounter this problem when the file system data structures like /etc/mtab or /etc/fstab gets damaged. If you’ve a new version of mount, then you should empty or delete the /etc/mtab file during boot. When these data structures get damaged, file system corruption occurs and you come across significant data loss circumstances.

In order to sort out the file system corruption problem, you are required to format the hard drive and reinstall operating system. This process will replace your damaged file system with new one and make your system working. But this process has a downside that it removes all of the data from hard drive and cause complete data loss that requires Data Recovery Linux for retrieving data. Recovery is possible through third-party applications, known as Linux Recovery software. The tools thoroughly scan the affected hard drive retrieve all of the lost data from it. They are completely safe and easy to use.

Stellar Phoenix Linux Data Recovery is the best ever made and the most advanced application that handles all types of data loss situations. It is compatible with most major distributions of Linux including Debian, RedHat, SUSE and Fedora. The software supports recovery from Ext4, Ext3, Ext2 and ReiserFS file system volumes.

In Linux operating system, GPT (GParted) is a useful tool that facilitates you to create, resize, move, delete, copy and check the hard drive partitions/volumes. It also copy file system on newly created partitions. It is helpful to create space to install new operating system, copying data stored on hard drive, mirroring one volume with another and recognizing disk usage. In some cases, using this tool may become problematic. It might damaged Linux superblock and lead to critical situations of system inaccessibility and possibly data loss. At this point, you are required to opt for Linux Data Recovery to get your precious and business-critical data back.

Sometimes, when the disk resizing, copying or any other GParted process is running, few read/write errors might terminate the phenomenon. Subsequent to this serious incident, your hard drive volumes could not mount and you come across a number of error message. In such circumstances, when you run the fsck utility after rebooting the system to check integrity and consistency of file system and hard drive, conditions could remain same. Situation becomes critical on every attempt to fix this issue. Linux operating system superblock may get damaged and give you that indication through following error message:

“superblock corrupted, run with -b 32768”

Superblock is a metadata structure of Linux operating system that keeps record of all file system characteristics such as size, block size, empty and filled blocks, respective counts, location and size of Inode tables, size of block groups, disk block map and the disk usage information. When it gets damaged, you can not access data from your hard drive and Data Recovery Linux is required.

Linux file system keeps redundant copies of the superblock. You can correct the problem by using any of them. You can search and use an alternative superblock with the help of ‘mkfs -n’ command.

If the above method can not help you to sort out the issue, Linux Recovery is the way to go for successful retrieval of your valuable data. Recovery is potential through advanced third-party applications, known as Linux Recovery Software.

The tools powerful and efficient scanning mechanisms to methodically scan whole hard drive and extract all of the lost, missing or inaccessible data from it. With read-only conduct and rich graphical user interface, the software are pretty safe and easy to use.

Stellar Phoenix Linux Data Recovery is an advanced and robust application for assured recovery in all data loss situations. The software recovers data from Ext4, Ext3, Ext2, FAT32, FAT16 and FAT12 file system partitions. It works well with most major distributions of Linux including Debian, SUSE, Red Hat, Fedora 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.

Modern computers enable you to install two or more operating systems on a single machine and use those operating systems independently. This configuration is known as dual-boot or multi-boot. The most popular combination of dual-boot system is Microsoft Windows and Linux operating systems. In order to continue Linux installation on a Windows machine, you are required to create a /boot partition using the free disk space available on your hard drive. You are highly recommended to halt Linux installation process while creating space for the /boot partition. However, it may render your Windows hard drive partition inaccessible and cause serious partition loss. In such circumstances, you need to go for Partition Recovery Software to retrieve inaccessible and lost hard drive partitions.

In order to illustrate this problem, consider the underwritten scenario:

You use a Microsoft Windows installed machine that has two partitions- one boot partition and one data partition.

You run the Setup of Linux operating system to install it on free hard drive space.

You abort Linux installation process when it creates /boot partition for the Linux operating system.

You boot your computer with Microsoft Windows operating system and find out that your data partitions is not accessible.

Or

You are able to access the data partition, but if you use a tool that accesses information of partitions, it displays wrong information about the Windows partitions.

Root of the problem

The problem generally occurs due to corruption of MBR (Master Boot Record) partition table, when you abort installation process of Linux operating system. Hard drive errors might have been introduced by an interrupted installation of Linux operating system.

Resolution

In order to Recover Partition in such situations, you can try out the below steps:

Remove and recreate the damaged Windows partitions, if you have an updated and valid backup in place.

If the backup is not updated or is unavailable, you can opt for third party applications to recover lost or damaged hard drive partitions.

The Partition Recovery Software are suitable for virtually every partition loss situation in Microsoft Windows. They deploy advanced scanning techniques to efficiently handle partition loss and ensure absolute Windows Data Recovery. With simple and rich graphical user interface and non-destructive nature, these applications are totally easy and safe to use.

Stellar Data Recovery Software recovers lost, corrupted, damaged, inaccessible, or deleted Windows partitions. The software is designed for Microsoft Windows 7, Vista, 2003, XP, and 2000 operating systems. It salvages NTFS5, NTFS, FAT32, VFAT, FAT16, and FAT12 file system partitions.

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, 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.
