Journal Linux data recovery fails on mounted root file systems

Linux is one of the most popular open source operating system. It is the most outstanding example of free software and it can be customized according to the users’ need. It is a well renowned operating system for servers as it offers better reliability, usability, and availability like features.

Many organizations use Linux as their server operating system store their important and business critical data on Linux systems. But sometimes this reliable operating system may also get crashed and you may face serious problems. You may have two types of experiences with Linux system crash:

• In first type of system crash, the automatic journal Linux recovery succeeds and the system boot continues as normal.
• In case of second type of crash, the journal Linux recovery fails and you are deserted to a prompt where you have to consider which tool to use. In this case when you use fsck you will get disastrous results.

The Linux recovery fails in second type of crash because it was the result of root file system problems. Recovering root file system is quite different from all other Linux file systems.

When the fsck is run while booting the system, root file system is mounted as read only and other file systems aren’t mounted. The full journal data recovery Linux can easily be performed on the un-mounted file system, but not on the root file system.

The Reiser FSCK tool does not allow you to perform a complete repair on the root file system unless you boot your system with recovery disk. Ext2 and Ext3 allows the same.

It can not be said a wise to perform Linux recovery on the mounted file system. When you do so, the system would write the in-memory data back to the file system and everything will be messed up.

In such catastrophic circumstances, you need to use specially designed Linux recovery software. These software are known as Linux data recovery software and are made available by several data recovery companies.

Linux recovery software generally come prepared with interactive user interface and thus do not require any sound technical knowledge to achieve data recovery Linux. You need to simply select a powerful Linux data recovery software and start scanning process to achieve the required results.

‘File system with errors, check forced’ Linux Error and Recovery

Linux supports large no. of file systems like Ext2, Ext3 and ReiserFS. The latter two file systems support file system journaling, hence are less prone to file system corruption (as compared to Ext2) due to unexpected shutdown. Apart unexpected system shutdown, other causes that could corrupt these file systems are improper use of terminal commands, insufficient disk resources, user errors etc. While such situations, you cannot access your stored data and to restore it, you should use your recent data backup. But if backup fails or you find it non-existent, scan your hard drive using third party Linux recovery applications.

As a practical example, when you start your Linux-based system, you might receive the following error message:

“ contains a file system with errors, check forced”

You get another error message describing that you should run fsck manually.

You get such file system error message if one or more critical data structures are corrupted or damaged. Linux file systems are made up of data structures like, superblock, inode, extents, cylinder groups, and block bitmap etc, If any of these data structures get corrupt, you get errors like above.

You should try these fallowing steps to recover from such situations:

• First boot your system using Linux CD
• Enter the root password to enter into the terminal, when prompted for. It is recommended to enter in single user mode
• Run fsck on the affected partition with syntax: fsck
• Reboot the system
• If you still receive the same error message and file system is corrupt, you should recreate the file system by reformatting the hard disk. Formatting deletes all data, thus use your last backup to restore.

After formatting the hard disk, if you observe that backup data is damaged, not available and not updated; you need to use commercial data recovery Linux tools. These are specific applications that use powerful scanning algorithms to examine the logically crashed drives. With read only design and self-descriptive interface, these Linux Recovery software allow you to perform safe and interactive recovery. You can use them in any logical data loss case.

Linux Distributions can Freeze and Data Loss Occurs

Linux is an open source and its distributions form the community of Linux. The distributions consist of Linux system software and a set of applications. Many of these distributions are lying in the revising and improving period and almost three hundred distributions are lying there. Now-a-days these distributions have been molded to be used at different levels from desktop to server. A distribution can be defined as a variety of applications installed on the top of libraries which is adapted according to the particular version of kernel.

But sometimes these distributions face some critical problems like when any distribution like Ubuntu or Kubuntu is installed, the system experience some random hang like problems. The system hang usually happens after a successful run of the system for few minutes and when the system is busy doing something. The system becomes unresponsive while the pointer still moves. In this case you need to hard boot the system and CTRL+ALT+F1/BS/DEL also does not work at all.

The reason may be:
Bad power management settings
Graphic card driver is not working properly
Motherboard is about to fail

You can try the following work outs:
Try removing the connected hardware one by one to know if any one of them is causing the problem
Check for the power settings and for the functioning of the motherboard.
The main reason could be problematic device drivers. So try to find the related problem and run the solution accordingly.
As the last option, reinstall the operating system.

So you can go for either of the option based on your analysis. But if you have come to the stage of reinstalling the system software then all is safe apart from your data. The data will get lost which you have saved till as that would format the primary volume of your hard drive and thus will delete it.

Though for Linux recovery, you have better option of having Linux data recovery software. These software works for the main objective of data recovery Linux by scanning the hard drive with the use of some algorithms. To add to the ease factor of the users, these Linux data recovery software usually come with the interface which is easy to deal with.

The powerful scanning algorithm of this software enables Linux recovery at the best level. You can have Linux Recovery for any of the Linux distributions. The demo version of this Linux data recovery software will preview you the recoverable files along with the view of its interactive user interface.

UnionFS Corruption and Data Loss in Linux

In Linux operating system has a unique filesystem service called UnionFS which allows you to have union mount for other file systems. Union mount is a process through which you can have several file systems getting mounted at one time. These file systems will then appear as a single file system. The work of the UnionFs is to allow the directories and files of different file systems to form a single file system. These files and directories are known as branches.

When the branches are merged there occurs a virtual filesystem. In this way the directories which have same path within the branches will be seen together. A priority level is set among the branches while mounting them. These branches can be read only or read-write file systems. This allows the file system to appear like the writeable file system. But the weird situation step in if you modify the UnionFS branch directly. This can even lead you to the data loss condition which requires Linux recovery.

When the merging of the branches is done using UnionDS, after that pivot-root or switch-root is done, setting “/” to a new point in the current file system hierarchy. This does not allow to properly removing the UnionFS-layers at the time of shut down. At this time the mounted file systems can’t be unmounted properly and thus this becomes the reason of data loss in Linux.

For this reason the deleted or invalid inodes are added to the file system at each shut down. Data lost from Linux system is present on the hard drive in any case until it is overwritten. So based on this fact Linux recovery is possible through a software help. Data recovery Linux can be done by scanning the hard drive by the use of few algorithms. The data recovery software meant particularly for this are known as Linux data recovery software.

These software fulfill all the needs of the users to have data recovery Linux in any of the case. Usually these software come with a user interface which is quite easy to deal and any of the less technically skilled user can use it. the thing that you need to check is that the file systems you are using in this case are supported for Linux data recovery for the chosen one software or not.

This Linux recovery software is compatible with the file systems like Ext2, Ext3 and Reiser FS file system and for all the flavors of Linux like Red Hat, Suse, Caldera and many more. This Linux data recovery software is the complete solution for the data loss problems from Linux based systems.

Currently has loop partition layout’ Linux Error and Recovery

Linux-based hard drive is divided into two major types of partitions: data partition and swap partition. Data partitions are the basic partitions that contain system data, including that for starting and running the system in root partition. On the other hand, swap partition is responsible for holding hard drive extra memory and expanded system’s physical memory. In most of the Linux systems, fdisk is used to initially set the partition type. These partitions can be ext3 journaled, ext2, Reiser FS etc. But sometimes you may observe certain issues with these partitions. Thus, Linux Recovery experts suggest maintaining an updated backup of important data that is stored on hard drive.

Consider a scenario, you try to mount a Linux partition to install a Linux distribution and encounter a similar error message:

“/dev/hdg currently has loop partition layout.”

Where, name of partition, i.e. /dev/hdg, can vary. It can be /dev/had, /dev/sda tc.

Cause

If you are using a third-party boot loader on primary hard disk’s MBR, Disk Druid may fail to recognize your partitions
.
Partition layout is damaged

Disk Druid is the tool to manage partitions and associate mount points. It is a graphical tool that displays existing disks and partitions in a defined format.

Solution

You can follow these steps to recover from the situation:

If boot loader has been the issue, uninstall the current boot loader and install GRUB on MBR of primary hard disk.

If partition table is damaged, backup all exiting information files and folders and repartition the drive. Restore lost data using backup. If backup has not been taken, is damaged or incomplete, you can use commercial tools of Linux recovery.

Linux data recovery software are advanced recovery applications that can scan drive affected from logical data loss. These applications use some algorithms that completely analyze existing disk structure. After locating missing files and folders, they compare their location information with that of existing ones. All the procedures are safe. Also, the interface provided is interactive and offer easy Linux Recovery options.

When Document Mangling Occurs in Linux

In the operating system like Linux when you see that the document is mangled up then this may be due to some serious bug in it. In computer termology terms the word mangling means rewriting the file again if it is incompatible at the operating system level. This happens mainly at the networked systems. If the file names contain colons or backslashes then the operating system can take it other ways and can generate errors.

If the operating system like Linux gets failed then you left with no other option then to reinstall it.

But if the Word processor has some bug in it then the system would not crash at all but this bug can lead your system at the stage of data loss which is irretrievable. This condition certainly requires Linux data recovery. This kind of corruption can also occur due to several other reasons like due to some problem in the hardware, cabling used in the system, an electrically noisy environment.

This might occur if the cable is loose but this type of corruption is very slow. A serious obscure bug in Word Processor can become a huge cause of data loss in Linux. In this case you can’t escape yourself from data recovery Linux. You use this operating system very often and if the data gets lost due to some silly reasons like this then the case can be very drastic. Document data loss is one of the major cases that you need to handle in this case.

The documents on which you had relied for saving some of the most critical information are now at the stake of loss and rest of the other data are also standing at the same position. So in this case the tool which can assure you a perfect Linux data recovery is at the top level of demand. Linux recovery is handled through software utility which is particularly termed Linux data recovery software.

These software undergo a wide scan of your hard drive to get your organization back into action. These software retrieve data in the same state as you want i.e. they never change the actual content of the data. But side by side you need to bit careful as this may not be not so with all the Linux data recovery software that you enlist through the internet. So first undergo a brief analysis of the capabilities of the software.

This Linux data recovery software goes well with the file systems like Ext2, Ext3 and Reiser FS. This software allows you to have an easy use through its interactive user interface. The software is also empowered with the advance file mask option according to the file name, size and date of the file. You can have its free demo version from the website which will help you to answer many of your related queries.

Ext2 File System Recovery from Linux Data Recovery

Ext2 file is a Second Extended file system for Linux operating system which does not support journaling and is the predecessor of ext3 file system. The space in the Ext2 is split up into blocks which are further organized into block groups. The structure of the block group consists of a superblock, the block group bitmap, inode bitmap, followed by the actual data blocks. The work of the superblock is to retain the important information which is vital for the booting of the operating system.

As this information is very crucial, so the backup copies of it is maintained in every block group and only the first copy which is stored in the first block is used on the regular basis. There is a group descriptor table which keeps track of group descriptors. The group descriptor stores some values of like inode bitamp, block bitamp and the start of every of the inode table of each block group. But there are certain of the limitations with this file system related to the file format of the data and the operating system and if the number of files in the directory exceeds 10000 to 15000, the user gets some warnings.

Apart from this if the file system gets corrupt or deleted due to any of the cause then the hard drive data becomes inaccessible. You then encounter some sort of error messages This happens if the path that has been specified by the user to access the file is now beyond the reach of the operating system as the file system has become corrupt or has got deleted. This may also happen that the operating system refuse to boot as the required information which was there in the file system is now unavailable.

This creates a very critical condition to be handled and requires any solution for Linux Recovery. This solution particularly comes in the form of software which scans your hard drive for retrieving the data are termed as Linux data recovery software. Linux is a wide spread operating system which gives several of the features to the users and the file systems ext2 and ext3 give an add to them. Users rely on this for storing their most of the valuable data, but the incidents like ext2 corruption generates the need of data recovery Linux.

So in any of such circumstance go for the reliable Linux data recovery as the else case can ruin your data along with your business. This is always recommended as the less skilled software can overwrite the data and hence dragging few of your data to the impossible Linux data recovery category.

The user interface of this Linux data recovery software is very interactive and supports many of the features like advance file mask option, view to the file and folder properties. The demo version of this software allows you to save the scan information which is usable in Linux data recovery at the time of actual application of the full version. This Linux data recovery is capable of Ext2 Recovery, volume recovery even if the superblock or inode list is damaged.

Linux OS is Reliable and Secure

Linux is the name of computer operating system which is very easy and fast to use. This operating system has been designed for general use on the desktops, laptops and servers. But it is now being used for several of the purposes due to its advanced features like computer architecture support, stability, security, embedded systems, targeting of specific user groups and lots many. Internet is widely used by almost all of the users for collecting information and for lots other works.

In the current circumstances where more consistency and security is required at the server level, Linux operating system is now used as server operating system. This is due to its more stability and long uptime, and the fact that desktop software with a GUI is often unneeded, this has risen prominence in this area.

Linux’s open nature allows distributed teams to localize Linux distributions where it is not cost effective. Although its performance on the desktop is not as much as other operating systems but this is widely accepted where this issue is not of much concern.

This operating system is widely being used in embedded devices due to its ability of easily being modified like in mobile phones etc.Due to the feature of switching between the operating systems and support to many hardware and several of the advanced applications, this operating system is in huge demand in the revenue of the servers and desktops.This shows that the operating system is hooked up with several of the computer systems and giving the users much of the usability and ease of use.

Users are adopting this OS in a great pace. But as nothing is safe and no matter which technology is being used by Linux, it is not protective from data loss.The data loss can happen in this OS also and you can require data recovery Linux. The reason can be any out of human error including accidental deletion, system crash, virus attack and lots alike. So similar to other operating systems, you would need data recovery software applicable to specific OS. In this case this is called Linux recovery software.

This Linux data recovery software is compatible with the file systems like Ext2, Ext3 and Reiser FS and with all the flavors like Red Hat, Suse, Caldera, SCO, Debian, Mandrake, Sorcerer, TurboLinux, Slackware, Gentoo and others.

Using Device Mapper Can Protect Data in Linux?

Device Mapper providing the foundation of dm_crypt disk encryption in Linux.It is used to serve many purposes like mapping one block device to another and supporting logical volume management. Many users want that their data on the hard disk should remain encrypt else to be used by any wrong person. If your data is encrypted then either your computer system has got stolen or some nasty user is trying to get access to your data, you are pretty safe from the data leak point of view.

Using dm_crypt which is a see-through disk encryption subsystem in Linux Kernel and can be applied through Device Mapper as it is a part of its infrastructure only. Enabling the Device Mapper will allow you to create new logical block devices from portions of existing devices. The block devices then are mapped to devices that for our use are treated like normal drive partitions.

Once device-mapper is enabled, you then can enable dm-crypt itself; it goes by the name Crypt Target Support in the kernel configuration menu. After this loopback device support is enabled to use ordinary files as if they were real block devices and then the encryption type chosen is compiled into the kernel or set as a module.

The device mapper utility is then required to be installed and then the further procedure of encryption is carried out after this configuration. But in few of the cases you may not be able to access your data even which you had encrypted to prevent access of other unwanted users and you need Linux data recovery.

These are the cases when there is some accidental or intentional formatting of your disk, virus attack, system failure or some server corruption errors. This creates a weird situation to the users. It quite obvious that the data, you had encrypted, is itself so relevant that suffering data loss due to some of these kinds of reasons is not appreciable. In this case Linux data recovery comes at the most urgent category.

This Linux Recovery software scan the hard disk to retrieve the precious data and possess some of the most powerful features like support to for Ext2, Ext3 and Reiser FS file system volumes, user- friendly interface, view to the properties of recoverable files and folders and lots many.

This Linux data recovery software can recover file and folders under sub-directories even the parent directory is deleted or missing. Seeking the importance of time to the users, this Linux data recovery software has a feature through which you can halt the scanning process and view the results.

Kubunto Linux Data Loss While Configuring as a RAID

Every time the release of new file version of any operating system comes with a number of added features and functions. The same thing is with Linux flavors also. The entire user likes to take benefit of these advanced and new features and upgrade to the later versions. One such operating system file version is Kubunto 8.10 flavor of Linux operating system.

It features the KDE 4 desktop, high stability, better performance and several other advantages. It is the latest and furthermost software in the open source community. When you install Kubunto 8.10, you might lose your precious data due to your own mistake.

If you have two hard drives attached to your system, during installation, it will ask you the following question:

“Do you want to recognize RAID?”

By mistake, if you answer this question to Yes, you may fall in grave situations of data loss. Kubunto will made RAID of your two hard drives and thus will copy all the data of your hard drive 1 to hard drive 2.As a result, when you attempt to access your second hard drive, you will get only the mirror image of your data stored on hard drive one.

It will result into catastrophic loss of all your data from second hard drive. It is the most terrifying situation, which a Linux user could face and may put him/her in need of data recovery Linux.

Data recovery Linux is potential through Linux data recovery software. The copying processes of data from hard drive one to hard drive two might overwrite the existing data. But it is not necessary that all the data will be overwritten. It might be possible that the previously allocated memory locations are not allocated to the new data.

In this case, the data only from hard drive sectors which are not written in copying process can be recovered. Linux data recovery software are powerful third party utilities, which allow users to have quick and successful Linux recovery in most of the logical data loss situations. To have efficient Linux data recovery, it is extremely important to select a powerful and reliable Linux recovery software.

Corruption in Linux Due to Write Back Cache

Devices rely on Write Back method to fix slow performance issues because of slower RPM and seek-time Write Back Cache is a caching technique in which the modifications to the data in cache are not copied to cache source until completely essential. It is implemented on the hard drives to improve write performance. Through this method, the hard drive could signal the successful completion of writing process more rapidly than if this had to wait until data was entirely transferred to disk media.

Write back caching is available with several microprocessors including Intel. write back cache is extremely useful technique to improve write performance, but in some cases, like hardware failure and power failure, the write back cache memory does not get flushed out to the actual drive.

It may cause corruption of data. The completed writing operation creates several problems for journaled file systems, generally because they bank on knowing whether the write operation to the drive has finished or not. Journaled file system requires knowing that the log entry has made to the disk before allowing metadata to be written on the drive. When metadata has written to the drive, the transaction could effectively be deleted from log file and free up the log space.

Therefore, if write operations never make it to physical drive, the ordering is desecrated and the metadata and log could be lost, which results into the file system damage. File system is the most important data structure of a Linux system. It is extremely important to store and organize the data files and makes them easily accessible.

The operating system never directly interacts with the file physically. It just takes the reference from file system table and locates to the particular file. In case of file system corruption, the operating system could not find the reference of particular file and thus can not access it.

This whole scenario will lead to the inaccessibility of your precious data and finally the data loss. The data loss may harshly affect your business in terms of decreased revenue and market reputation, time and money.

In such catastrophic circumstances, the only thing you should think of is Linux data recovery. Data recovery Linux is the technique of retrieving your most valuable data from failed hard drive. Data recovery Linux is best possible through Linux recovery software. These software are capable of handling all of the logical data loss situations including file system corruption.

Test Disk Fails: Linux Recovery

On some occasions there might be some situation where you press any wrong key or you do some silly work, and unexpectedly, the file system of your Linux based computer refuses to function. Every time it takes place, the first thing you hear is “You ought to make backup.” your entire stored database becomes completely inaccessible and you may face critical problems. If the lost data include important business information, the data loss may possibly put you out of the business.

There are quite a few powerful solutions available, which could help you to save your precious data. In such problems, you should not panic. Linux includes a most powerful and amazing utility for this, known as ‘Test Disk’. It could recover your damaged file system and lost hard drive volumes. It is available with all Linux flavours.

To ensure successful recovery, you are recommended to follow the below given steps: Consider the type of hardware from where the data has got lost. It is required because the affected file system should not be of the primary volume. Backup damaged volumes.

It is essential to avoid further damage. Run Test Disk. In few seconds, it will show you the storage devices attached to your system. Select your affected device and choose proceed. It will ask you the type of volume; select the one which you have.

But it could not fix the severely damaged hard drive volumes and can not solve the harsh file system corruption related issues. In such circumstances, to pull out your valuable data from inaccessible hard drive, you need to perform data recovery Linux. Data recovery. Linux is easily performable by third party tools known as Linux data recovery software.

A powerful and highly developed Linux recovery software is required to have complete Linux recovery. Linux recovery software come with great power of scanning the affected hard drive and can extract data in each and every case of data loss.

Library File Errors in Linux

When you start any application on your Linux system, you may come across with the following error message:” Program name: error in loading shared libraries: lib xxx...so. X: cannot open shared object file: No such file or directory.” After this error message, the application gets terminated unexpectedly and you can not use it any more.

This trouble occurs with the applications which are using shared libraries. This problem occurs if your computer has incompatible libraries to the applications or the applications and system have mismatched file versions of libraries. Another reason of this problem could be the corruption to system files.

The corruption could be the result of virus attack. Due to corruption, the application could not access the required files and fails to start. Regardless of the reason, this error message leads to the inaccessibility of your precious data stored on the hard drive and ultimately leads to data loss. For saving your business critical data, it is extremely important to solve this issue as soon as possible.

To work around this issue, you can use the following two options: If the problem is due to incompatible application or system libraries, update them. If it does not work, the problem is due to system file corruption and it needs to reinstall the operating system. Reinstallation of operating system is the ultimate solution of all the system related problems.

But it also has a downside which can lead to data loss. Reinstallation requires hard drive formatting and formatting wipes all the data stored on the drive. you need for something which can perform data recovery Linux to recover your lost Linux data.

The data recovery Linux is feasible with the application of Linux recovery software. . They can carry out data recovery Linux in all cases of data loss. These software are highly developed and do fast and effective Linux data recovery.

You can use this Linux data recovery software for all flavors of Linux to recover all sorts of lost files including documents, spreadsheets, library files, application data and many alike. User interface of this Linux recovery software is very cool looking and thus allows you to have trouble-free data recovery Linux.

Error in Linux “No such file or directory”

When you try to install device drivers on your Linux system, you might fail to do it. It could be due to incompatibility of the operating system Kernel with your device driver or device. You need to install the latest version of Linux kernel. It may include ‘forcedeth’ patch, which is capable of resolving most of the incompatibility issues.

After installing the latest version of Kernel, when you reboot the Linux system, you might face the following error message:“fsck.ext2: No such file or directory while trying to open /dev/hda8. The super block 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 super block is corrupt, and you might try running e2fsck with an alternate super block: e2fsck -b 8193 fsck failed.”

As stated in the error message, this problem generally occurs due to super block corruption or file system corruption. Super block and file system are two most important data structure of Linux system. Proper functioning of both these is required for ensuring effective working of the system. After corruption, the operating system could not locate the file and thus can not retrieve it.

To solve this problem, you need to install a fresh copy of super block and file system. It is possible through formatting of the hard drive and reinstallation of operating system. Though, it will remove the errors but will also erase all the data stored on your hard drive. It is the worst scenario of data loss and needs Linux data recovery to get it fixed.

Linux recovery software are easy to use and thus allow you to have simple and fast data recovery Linux. Linux data recovery is feasible with the application of third party Linux recovery software known as Linux data recovery software.This data recovery Linux software works well in all data loss cases and allows Linux data recovery for all sorts of files.

File System Corruption in Linux

Linux and other UNIX based operating systems such as AIX uses Fsck utility that is used for checking consistency of the file system. Generally it runs automatically at boot time when the file system is detected by the operating system in an inconsistent state representing a non-elegant shutdown, such as power loss or crash. fsck utility offers options for either synergistically repairing corrupted file system.

Automatically considering how to work around the specific issue (so the user does not have to answer for any question), or reviewing the issues that need to be solved on a file system without really fixing them. Sometimes, you may find that when you boot your system, you get an error message. This may be an fsck error message stating:

File system is Clean.File system seems to have fatal corruptions. Running with--rebuild-tree is required.*ev/sda1: clean 33/522240 files, 80815/1044193 blocks [fail]* fsck failed. Please repair manually.

As the error message suggests, the problem has occurred due to deadly corruption in the file system. Due to corruption in the file system, the boot sector of the system can’t be accessed by the operating system. It can create very lethal situations for an organization or an individual user and can result into the severe data loss.

File system corruption is the most serious situation of data loss that could occur in any system. Ultimately, you fall in need of data recovery to get your data back. Data recovery is feasible through making the use of data recovery software. Data recovery software for Linux systems are known as Data Recovery Linux software.

Linux recovery software are the inclusive data recovery Linux solutions for all likely circumstances. The market is flooded with the data recovery software of different brands and price tags. Selecting the right and appropriate one is really challenging and significant for perfect data recovery Linux.

Crashed Linux System Recovery

Linux Operating system consists of a Linux kernel which can be booted is known as Boot Disk. This disk can be used to boot the kernel, which then might load a root file system to any other disk. The Kernel on the Boot Disk generally should be told where to find the root file system. You can say that a boot disk contains everything that is required to boot a Linux based computer.

The advantage of this disk is that it is compact- anything required is stored on a single disk. It is mainly beneficial in case of a system crash where you can boot the system through Boot Disk and can save your data to other location. There are some unfortunate situations where your Linux operating system crashes and you don’t have a boot disk to boot the system.

The only way that can solve you problem in this case remains are the reinstallation of the operating system. But it is not a safe way as it needs the hard drive formatting and wipes all of the data stored on the hard drive. It causes the nightmare of the data loss can puts you in serious problem. If the data is of great importance then create hazards for your business also.

The way is to use data recovery software to recover the data and save it to another hard drive or storage media and then format the hard drive and reinstall the operating system. The data recovery software that can be used in this case are known as Linux recovery software.

Linux data recovery are the data recovery Linux solutions to recover all of your data before going out of the business. These software are fairly easy to use and you can perform data recovery Linux by yourself. These software use scanning algorithms for extracting the lost data and recovering it. You need to install Linux data recovery software on any other system that is in working condition and attach your hard drive to it and perform scan.

You can easily find a Linux data recovery software that can be installed on a Windows operating system and you can perform data recovery Linux by attaching your hard drive to this system.

Error in Linux” Can’t locate module”

While starting your Linux system, at boot time, the process may get terminated and you might come across with the following error message:” Can’t Locate Module ”After this error message, the system does not boot and none of your data can be accessed from it.

If modprobe, rmmod, or insmod files are not able to find a module this error message may occur. the system can not access the required system files to boot and thus shows the error message.

Modprobe- It is a system file that intelligently adds or removes the modules from the Linux kernel. It looks in module directory “/lib/modules/uname –r” for all modules and other files.

Insmod- It is a trivial tool for inserting a module in the Linux kernel. It takes the module from standard input. If this tool tries to link the modules inside the Linux kernel, the error messages are thrown.

Rmmod- It uploads the loadable modules from running Linux kernel. It tries to upload the set of modules from kernel, with restriction that they aren’t in use and that they aren’t referred to by other ones. These system files can’t perform their tasks if they are corrupted. The corruption could be due to virus attack, file system corruption, improper system shutdown and so on.

The only solution to work around this problem is to format the primary partition of your hard drive and reinstall the operating system. It will remove all the errors and will install a new set of data structures and a fresh Linux kernel. Though, formatting will remove the errors, but also delete the data stored on the primary partition.

The situations can become worse if you have not partitioned your hard drive and stored all of precious data on it. You need for a solution which can recover your lost data and can save you and your business. These solutions are available in the form of Linux data recovery software.

Linux data recovery software is the most influential and user friendly recovery tool. This third party application is specifically designed to meet different users’ data recovery requirements. The data recovery Linux software are easy to use and thus do not require any sound technical knowledge from user’s side.

Accidental Use of FSCK Causes Data Loss

FSCK is a system utility in Linux operating system used for checking file system consistency. It runs automatically during boot when the operating system detects that the file system is in the inconsistent state, indicating a non-graceful shutdown, like power loss or crash.

FSCK provides options either for interactively repairing the corrupted file system, automatically deciding how to resolve the specific problem, or reviewing the issues which require being determined on a file system without resolving them. FSCK could also be run manually by system administrator if there is any problem with the file system.

Generally, the FSCK command is run non-interactively for preening the file system after a sudden system halt in which the file system changes weren’t written to the drive. Preening automatically resolves any basic file system inconsistency problem and doesn’t attempt to repair more critical issues.

While preening the file system, the FSCK command solves the inconsistencies it anticipates from such abrupt halts. In more serious circumstances, the command shows the error messages and gets terminated. You need to run the FSCK command manually to fix the file system issues. You can run the FSCK command only if you have system administrator privileges on your Linux system.

The manual running of FSCK command is possible though the shell prompt. FSCK is extremely important Linux command and can cure most of the file system inconsistencies, but if you use this command manually on a mounted file system, it can cause potentially severe data loss.

In these situations, your data becomes inaccessible and you may fall in need of data recovery Linux to save you and your business. The data recovery Linux is feasible with the application of Linux data recovery software. Linux data recovery software are the applications which are able to perfectly scan the entire hard drive and extract all of the lost data from it.

This software employs the most influential hard drive scanning algorithms and ensures absolute extraction of all your lost data. To perform data recovery Linux in case of file system corruption, this Linux recovery software includes powerful feature of RAW Data Recovery.
