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.

The Linux operating system is supposed to be the most regularly updated operating system among its counterparts. Apart from this fact, for its advanced technology and features, a large number of users prefer Linux. But, in Linux, the user can not get everything preloaded just like Windows. There is an unique command for each operation in Linux and from the long list of regularly used commands, the ‘mount’ command lets the operating system to learn about the file system and lists in the file system hierarchy of the computer, which lets us access the the particular drives. However, sometimes, the ‘mount’ command fails to work and the OS can not be able to learn the drives resulting in the inaccessibility of them. In such situations of data loss or inaccessibility, Linux data recovery can help you recover your valuable data back.

There can be a possible file system corruption, which has led this abrupt behavior of the Linux system following the failure of the ‘mount’ command. The ‘fsck’ is a built-in command-line utility in Linux operating system, which checks the consistency of the file system and repairs the same, if finds any error. After encountering the above situation, if you try to mount the drives using the ‘fsck’ command, you may encounter some more error messages. The error messages may be read as below:

“[/dev/mapper]fsck -a /dev/mapper/mpath0p1
fsck 1.35 (28-Feb-2004)
ext2fs_check_if_mount: Input/output error while determining whether /dev/mapper/mpath0p1 is mounted.”

OR

“fsck.ext2: Bad magic number in super-block while trying to open /dev/mapper/mpath0p1
/dev/mapper/mpath0p1:
The superblock could not be read or does not describe a correct ext2
file system. If the device is valid and it really contains an ext2
file system (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>”

The above error messages clearly state that the file system has been corrupted. In order to resolve the issue, you need to boot the Linux system from the safe mode and run the ‘fsck’ command to repair the corruption. However, if the file system has been severely corrupted, ‘fsck’ simply exits without doing anything. In such a case, if you are an expert user, you can input the next super-block address or the size of the same to the ‘fsck’ command, which can help the utility to gather the information from the next super-block and do the job.

However, failing to the above resolution method, you need to opt for any Linux drive recovery software to bring back your precious data.

Stellar Phoenix Linux Data Recovery is an efficient as well as 100% risk-free Linux recovery utility of the current time. The utility has been trusted by a number of users for its power-packed scanning algorithms and ability to recover lost, deleted, formatted or inaccessible data from any troubled Linux drive irrespective of the complexity of the data loss situations.

Linux is an open-source operating system that has various distributions, which include Fedora Core. It is an OS, which enables you to access latest open source applications. The OS uses a disk structure similar to various other Linux distributions and may face the same problem of corruption as others do. Corruption makes it inaccessible and unbootable, causing severe data loss. In such critical situations, you are required to opt for Linux data recovery solutions to get your valuable data back.

In a practical instance of the disk structure corruption in Fedora Linux OS, you may encounter the below error message when you reboot the Fedora operating system-based computer after it freezes at startup-

“EXT-fs: dm-0: couldn’t mount because of unsupported optional features (2000200)
mount error 22 – mounting ext 3″

Subsequent to the above error message, you might get further error message that says-

“kernel panic – not syncing: Attempting to kill init.”

After this error message, Fedora operating system cannot detect and access Linux hard drive partitions when you try to perform data recovery Linux using Linux Rescue CD. When you try mounting the disk manually, it says that the disk has invalid arguments and thus it cannot be mounted.

Grounds of the problem
As stated above, this problem occurs due to corruption to the logical structure of the Linux hard drive. It may also occur if disk data structures, like Superblock and file system, are damaged. Corruption might be the outcome of virus infection, improper system shutdown, operating system malfunction, and other similar reasons.

Resolution
Use any of the below Linux recovery solutions to sort out this problem-
Boot your Linux computer using the Rescue CD and then run pvscan command for checking the logical volumes.
Run fsck -C -y /dev/hdXX command.

If none of the above Ext2 recovery methods work, you are required to format the disk and reinstall operating system. Although, formatting can fix all disk related problems, but it also cause serious data loss. In such situations, Linux File recovery software are required to retrieve lost data after formatting.

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.
