Data Inaccessible and Block Corruption in Linux

The Linux operating system consists of Ext2, Ext3 and Reiser FS file systems. These file systems stores the data in the form of Data Blocks. Blocks are used to decrease the chances of internal fragmentation and decrease disk seeks time when reading or writing a large amount of data on the disk.

Every data block group consists of a super block, an Inode bitmap, subsequently the actual data blocks. The super block of your Linux operating system stores significant booting information.
The group descriptor holds the value of block bitmap, Inode bitmap and the starting of the Inode table for each block group. This data structure of the Linux operating system not only reduces the disk fragmentation but also make the data storage very simple.

When you find that your Linux system responds very sluggish. It may be possible that the system crashes, hangs, and freezes. Such situations occur if there is a lost of fragmentation on the hard disk. The disk fragmentation can occur in case if you are using blocks also.

The data stored on the drives becomes entirely inaccessible. You need to format the hard drive to solve out this problem. Formatting of the hard drive completely removes the existing file system and installs a fresh file system that is free from errors. But, along with the file system, disk formatting also removes the data stored on your hard drive.

It results in very serious condition of data loss. You need to recover them at any cost to save you and your business. Data recovery in such situations is possible using data recovery software. For this particular problem, you need to use Linux data recovery software. These are the data recovery tools designed to recover the lost data from Linux based computers. These software are very easy to use and doesn’t require any sound technical knowledge.

You can get the free demo version of this Linux recovery software from company’s website to check the user interface and powerfulness of the software. The demo version is able to show the complete preview of all the images, documents, spreadsheets and hexadecimal view of the remaining files.

CLI Functions and Data Loss in Linux

When ever you face an erroneous condition with your Linux based computer, you can try out to diagnose it yourself with several troubleshooting tools come bundled with Linux operating system. Knowing about these utilities, and how to efficiently use them, can assist you to overcome several of the general problems on your computer.

Here is the list of some weapons in your munitions store against Linux problem like Strace, Ltrace, Lsof, Top, Traceroute, and PingHexdump

These tools are the functions of CLI or Command Line Interface of Linux operating system. You can perform several such tasks using these tools that can’t be done using GUI or Graphical User Interface. CLI tools directly interact with the core of the operating system and can solve out your problems. But sometimes, dealing with these functions, can create big problems for you.

The most general mistake made by the Linux users is changing the Root directory of the File System while dealing with CLI functions. After changing the name of the Root directory, your system won’t boot up and you may get some sort of error message like “Kernel Panic” error. In such situations, you can’t access the data stored on your Linux hard drive and the data goes at stake of loss.

The data recovery in such situation becomes essential and you need for data recovery software. For Linux operating system, these data recovery software are known as Linux data recovery software. You can use these data recovery software in all kind of data loss situations. These data recovery software are able to recover all kind of data.

This remarkable Linux recovery software is compatible with all flavours of Linux operating systems and can recover lost logical volumes and data from them based on Ext2, Ext3, and Reiser FS file systems.

Linux Recovery Using SystemRescueCD

As we know that Linux has become more popular day by day. In Linux SystemRescueCD is a Linux operating system distribution that runs from a bootable disk (a Live CD) or USB or Universal Serial Bus stick. This CD is useful for repairing unbootable operating systems and recovering data from them after a system crash.

SystemRescueCD was designed by a team directed by Francois Dupoux and is supported Gentoo Linux distribution. This recovery CD is capable of providing GUI supported environment using the Linux frame buffer option for tools like GParted. This CD is based on the stable 2.6.24.05 version of Linux Kernel with the ReiserFS file system support.

This recovery CD has several outstanding features like recovering resized partitions, editing disk partition table, can recover from dual boot system, memory testing and hardware reconfiguration. In this way, SystemRescueCD is a great tool provided for the Linux users that can help them in getting all their lost data back.

Using this CD, users can restore the system to its best working situation. It works with almost all of the Linux flavours supported by ReiserFS file system. Under some situations, Linux users can’t recover their data using SystemRescueCD. It can be due to several reasons such as File system mismatch, system doesn’t boot from the CD, and severe operating system corruption where no file system and system restore entry exists.

In this condition you need for data recovery solutions to get your lost data back. For this case, data recovery solutions are available in the form of third party data recovery software known as Linux data recovery software.

Linux data recovery software are the applications designed to meet the different users’ requirements related to the data recovery. The Linux recovery software are very easy to use and the data recovery can be performed by following some simple steps no matter you have any sound technical knowledge or not. The software can recover Ext2,Ext3 Recovery as well.

There is no limitation to file system support with this software as it can recover data from all Linux file system based hard drive volumes such as Ext2, Ext3 and ReiserFS. This Linux recovery software is capable to recover the data from all flavours of Linux including Red Hat, SUSE and Ubuntu.

Ext3 File recovery

Ext3 (Third Extended) File System is a Journaled file system used in Linux operating system. This is the most popular Linux file system. It was the first journaled Linux file system. It is the default file system for some of the popular Linux flavours.

Ext3 file system has numerous data structures for storing the file system information. These file system data structures are also known as metadata structures. The important metadata structures contained in the Ext3 file system are super block, boot block, Inode table and descriptor table.

In Ext3 file system, both file contents and metadata are written to the journal prior to be written to the main file. Because the Journal is relatively incessant on the disk, this can improve system performance in some circumstances. In other situations, performance gets decrease because the data must be written twice.

Ext3 file system is treated as a reliable file system as it uses Journaling methods. But there are some conditions where you may find that your operating system can’t find the specified file on your computer hard drive and shows some sort of error messages. These error messages are “File Not Found”, “Can’t open the file” and “The file is no longer exist”.

This problem occurs due to corruption or deletion of Ext3 file system. In this case, the operating system can’t find the path of the file for that you have requested. In these situations, the data on your Linux hard drive becomes inaccessible and it can cause data loss.

If the lost data was very important, it becomes essential to recover them. You can recover these lost data with the help of data recovery software known as Linux data recovery. Ext3 file recovery are special data recovery tools that can help you in recovering your lost data from Linux hard drive in cases where data has been lost due to File system corruption or deletion, accidental deletion, missing logical volume, virus attack or operating system corruption.

Logical Volumes of Linux Can be Recovered

Linux OS is widely used now a day because of its popularity and fast processing. This Operating System consists of volumes that refer to the logical partition of Linux hard drive. Linux hard drive volumes are the hard drive partition that has different file systems and different accessing privileges. It is a logical interface used by operating system to access the data stored on computer hard drive.

Linux operating system volume is handled by Logical Volume Manager. The hard drive is divided into several volumes due to following purposes:

Separation of user files and operating system files

Keeping frequently used data and programs close to each other

Using more than one operating system

Increasing overall system performance

We can compute that Linux hard drive is divided in different volumes. It decreases the risk of data loss in case of operating system failure. The structure of Linux Volume depends on the File system used by it. There are three popular Linux File Systems- Ext2, Ext3 and ReiserFS.

Although we know that dividing the hard drive in logical volumes in good idea to save your data but sometimes you may find that your logical Linux volumes become inaccessible or invisible due to deletion or corruption in it. The Linux logical volumes may get deleted by:-
Accidental deletion of partition

Power Surges

When your OS cannot access hard drive

When the above situation occurs and the volume deletion may take place. Your critical and significant data stored on them can lost or become inaccessible. It may create several problems for the people who are dependant on these lost data.

The Linux volume can be recovered when the logical volume is deleted, in general, only the partition table of the volume is deleted from the table and the data become inaccessible. But the data still remains on the disk. You can recover the lost logical volume and data with the help of data recovery software.

Linux recovery software can recover data in all possible circumstances of data loss including Logical volume deletion, accidental deletion, operating system corruption and virus attack. This Linux data recovery software uses advanced searching algorithms to search and locate the lost data and recover them at their original location in original format.

Linux and Ext3 Recovery Using Ext3grep

Data loss can take place to everyone earlier or soon after, a single second after you press Enter you understand your mistake, you just removed a valuable file or folder from your Linux system consisting of no back up. And in shock you see the running month flash before your eyes as you understand in pain what you will have to do all over again. As you know that files and folders are never in fact deleted, at most overwritten by new data.

Therefore, you remount the drive read only as soon as possible. In Linux there are several methods to manually or automatically recovering the lost data. Almost all of the operating systems contain some or other undelete tools or methods. When it comes to the Linux operating system and its Ext3 file system, there is a tool called as Ext3grep that can help you in doing the same. Ext3grep is a Linux utility that can help you in recovering completely deleted files on an Ext3 File system based volume.

The best part of this tool is that you can use it tool in all possible situations of file loss where you have accidentally deleted the file by bypassing the trash bin or by emptying it. Though Ext3grep is a very important and useful application to retrieve your lost data but there are some major drawbacks with it. Using this tool, you can’t recover a file larger than 2 GB and also the tool is not useful in case if the data loss has been occurred due to some other reasons like operating system corruption, virus attack, file system corruption and logical volume deletion.

Therefore the data using Ext3grep can’t be recovered and it can put you in a big trouble. But there is no need to panic. There are many other methods to recover data in such situations. These methods are known as data recovery solutions. In this case of data loss, these solutions are available in the form of Linux recovery software.

The Linux recovery software are compatible to recover the data in all of the situations where other tools can’t do. You can perform recovery using these data recovery software very easily whether you have any prior technical knowledge or not. This software can is very proficient in Ext3 Recovery and Ext2 Recovery

Recovery Using System Imager in Linux

The process of recovering data is one of the most long term processes for a computer user. Imaging tools or software programs, open source and commercial, makes compressed images of the hard drive data of your computer system and stores it on a central server. Later these images can be used to restore your system or roll out new ones.

System Imager is the useful and popular open source imaging software used in Linux and other Unix based computers. System Imager has several benefits over traditional drive imaging methods and tools. It uses rsync to store the image remotely, and can do the backup or full install in just a few minutes.

We know that the Images created by System Imager are the complete copies of the file system and system files of your Linux computer. You can update these images on the server if you make any change to the data on client system. System Imager is the best and easiest method that a general Linux user can use to ensure maximum security and protection of their data from loss. Though this software takes some more time to configure but it’s simple to do the same.

We can use System Imager on all of the flavours of Linux but there is main disadvantage of it. There is no technical support available for this software. if it creates some problems, there is no tech guy to assist you to resolve your problem and thus it may not work and you may fail to restore you system using this tool.

In such conditions, the data stored on your Linux hard drive may get lost and can lead to critical situations for your data and business. Here you need for what is known as data recovery Linux solutions. For this particular case, data recovery solutions are available in the form of Linux data recovery software.

Linux recovery software are easy to use and can perform data recovery by yourself without having any prior technical knowledge of using data recovery software. Linux data recovery software are the data recovery tools designed to meet the different user requirements. This software can recover data from ext3 files as well with the help of Ext3 recovery software .

Dual Boot Linux System Corruption

We know that running more than one operating system on a single computer system is called Dual Boot process and the system on which dual boot has been applied is called dual boot system. There can have two or more different operating system on different hard drive partitions in dual boot.

For each operating system, the partition on which it is stored is primary partition. This is a very helpful and easy method for the users who want to run more than one operating system on the same PC or they want to use some kind of application that specially run on a particular operating system.

Sometimes any problem to the one operating system occurs; other operating system will also get affected. This problem generally occurs with a system on which you are running Windows and Linux operating system. When you perform a reinstall of the Windows operating system, you may find that Linux operating system won’t work.

When one of the process fails general problem occurs when the file system and boot loader of the Linux operating system get corrupted and it can’t boot up. In these situations you need to format the particular partition and reinstall the operating system. Reinstalling the operating system is an easy to perform task that can solve all of your operating system and file system corruption related problems.

However sometimes it can be very costly especially in case if you have stored your critical data on the Linux partition. In these situations, you need to recover these lost data to save you and your business. Data recovery is possible with the help of data recovery software known as Linux Recovery software.

These software are fairly easy to use and can perform data recovery in almost all possible cases of data loss including hard drive formatting, file system corruption, boot loader corruption, virus attack and operating system corruption.

This Linux Data recovery software can recover all types of data including documents, pictures, movies, songs, and application program files. This data recovery software is compatible with all flavours of Linux operating system and can recover missing or lost Linux volumes based on Ext2, Ext3 and ReiserFS file systems.

When fstab Boot Failure Occurs in Linux

When you try to boot your Linux system, unfortunately you may find that your system stucks in the boot window or it aborts the boot process. This situation may occur and you need to restart your system. After restarting you again come across the same situation

Now the problem might be more drastic when you did not know the cause of the error. This problem usually occurs if fstab directory contains wrong or corrupted or missing information form system related mount points. In these situations the boot process aborts when the operating system tries to write log information to the relevant directory. The fstab or File system table file is generally found in Linux or other UNIX like operating system as the part of the system configuration.

In general this may lists all the available system disks and disk volumes, and indicates how they are to be initialized or otherwise integrated into the overall file system of your Linux computer. This file is mostly used by mount command.

Therefore the reason might be crucial and it is very significant to resolve this problem very quickly for smooth running of your Linux system. You can work around this problem by reinstalling the operating system as it is the system related problem.

A common user usually reinstall the Operating system without any problem. But the results of the same are very drastic. The data stored on the primary volume of your Linux hard drive will be lost. The situation becomes more critical in case where you have stored all your important data on the primary volume or you even haven’t partitioned the hard drive.

The situation may take a wrong turn and your precious data stored on your hard drive will be lost and you need to recover them. You can recover data using Linux recovery solutions available in the form of Linux data recovery software. The Linux data recovery software are easy to use and fast performing data recovery tools that can help you in retrieving all of your lost data from Linux hard drive and perform ext2 recovery as well.

Using Disk Druid Data Loss in Linux

Linux users always know that the Disk Druid which is used for various Linux flavors for editing, creating and deleting the Linux partitions. It is commonly used to partitions the hard drive for you. This program provides many user friendly commands like Add, Edit, Delete and Reset options for making changes to your existing Linux partitions. Linux refers to disk partitions using a combination of numbers and letters. You can make swap partitions also, using Disk Druid component.

Swap partitions are used to support for Virtual Memory. You should always make virtual partitions to increase your system performance. But there are some situations where your Linux hard drive may fail or become inaccessible when your edit, add or delete any logical volume. This problem occurs due to some deficiencies in Disk Druid utility. These deficiencies include:

  • You can create only 3 primary partitions
  • The size of the swap partitions must be large enough even if allowed to load all the remaining disk space
  • If the disk partition is not selected, it will perform the same task on all the partitions of the disk
These situations can lead to catastrophic conditions of data loss if you don’t keep these things in mind while performing disk partition. You need for data recovery if the lost data was very important for you and your organization. You can recover your lost data with the help of Linux data recovery software.


Linux recovery are the powerful and easy to use data recovery software that can help you in all possible cases of data loss where the data has been lost due to logical reasons such as lost hard drive volumes, hard drive formatting, accidental deletion and operating system corruption.

Phoenix Linux data recovery is the most widely used and robust data recovery Linux software that you can use to recover your lost Linux hard drive volumes and data. This software employs extremely powerful data recovery algorithms to search and locate the lost data and make the data recovery Linux possible.

Recovery after Disk Failure in Linux

The Linux computers are similar to other operating system based computers like UNIX and Windows in case of hardware configuration. There is a similar hardware problem in all these Linux based systems. When it comes to the physical system crash, the reasons are also much similar.

The disk failure is caused by the reasons that are responsible for other computers. The most disastrous hardware failure in Linux computer is total hard drive failure. It can occur when a computer is kicked or dropped, though it can also happen because of old age of the hard drive.

The read write head crashes onto the disk platters, by this means of trashing the head, and keeping everything/anything on that platter from being readable. If the hard drive has only one platter that means everything. This failure can occur due to electric failure.

The data stored on the computer hard drive can’t be read and it can lead to the nightmare of data loss. In these conditions, you need to recover your precious data to save your business. You can recover the data from these totally failed hard drive with the help of data recovery service or in case of logical hard drive failure you can choose Linux Recovery Software.

After repairing or replacing the damaged hard drive parts, the associates use the data recovery software to recover the data from these drives. For this case, the Linux Data recovery software is used. Data Recovery Linux software can recover the data in almost all instances of data loss.

This software can recover the lost data in all possible cases of data loss after repairing the damaged hard drive. It is a non destructive and read only Linux data recovery software that recovers the data in its original format without making any change in the original contents. This software can recover the data from Ext2, Ext3, and ReiserFS file system based Linux volumes.

Ext3 File System Corruption in Linux

Ext3 is the most popular file system used in Linux operating system. This is the most efficient and fast Linux file system. It was the first journaled Linux file system. It is the default file system for some of the popular Linux flavours. The Ext3 file system has several data structures for storing the file system information.

The popular name for these file system data structures are also known as metadata structures. The important metadata structures contained in the Ext3 file system are super block, boot block, Inode table and descriptor table. In Ext3 file system, both file contents and metadata are written to the journal prior to be written to the main file.

We know that the Journal is comparatively incessant on the disk, this can improve system performance in some circumstances. In other conditions, performance gets decrease because the data must be written twice. Ext3 file system is treated as a reliable file system as it uses Journaling methods. But there are some situations where you may find that your operating system can’t find the specified file on your computer hard drive and shows some sort of error messages.

These error messages are “File Not Found”, “Can’t open the file” and “The file is no longer exist”.
The cause of the problem might be due to corruption or deletion of Ext3 file system. In this case, the operating system can’t find the path of the file for that you have requested. In these situations, the data on your Linux hard drive becomes inaccessible and it can lead to the nightmare of data loss. In these circumstances, if the lost data was very important, it becomes necessary to recover them.

You can recover these lost data with the help of data recovery software known as Linux Data Recovery. Linux recovery are special data recovery tools that can help you in recovering your lost data from Linux hard drive in cases where data has been lost due to File system corruption or deletion, accidental deletion, missing logical volume, virus attack or operating system corruption.

This software can recover the lost data from all flavors of Linux operating system Ext2 Recovery, Ext3 Recovery and ReiserFS file system

Corruption in Inode can Occur in Linux

Inode is a standard data structure on Linux and other Unix-based operating system that retains all information about a file excepting the name and actual data of the file. When a file system is created in Linux the inode is created as well. The Inode ensures the entry of any file that is identified by a unique numerical number.

The use of inode is essentially used to store data that can be accessed and used efficiently. There are different types of applications which uses different types of data structures. Inode stores information about the files like group and user ownership, file type and access privileges (read, write and execute). Inode is used to organize the files on a Linux computer. It uses a hierarchy of directories that is controlled by Root Directory. Root directory contains a series of sub directories and it controlled by Inode.

Each file system has a specified Inode and the information of Inode is stored in Inode Table. When a new file is created, it is allocated both an Inode number and file name. file name is used by the user to identify the particular file and Inode number is used by the operating system to recognize a file in file system in order to access them when the user request for the particular file.

While access a particular file and try to open it, you may come across some sort of error message regarding to file access like “file not found” and “file can’t be accessed”. These error messages occur when the Inode get corrupted and operating system couldn’t identify the requested file. In these situations, the files stored on the hard drive become inaccessible and may lead to nightmare of data loss.

In this situation, you need to recover your lost data to make them available. There are various options for this problem and need some technical knowledge of Linux file system or you can simply perform this task with the help of Linux data recovery software.

Linux Recovery Software uses advanced searching algorithms to search and locate the lost data and recover them in their original location .Linux data recovery software is well-know and fabulous data recovery software that can recover lost data from your Linux computer in all possible cases of data loss.

This Data Recovery software is capable to recover lost data from Ext2, Ext3, and Reiser FS file systems of Linux operating system.

Linux Operating System Errors and Resolution

Linux is the most popular operating system so far as security and performance is concerned .It is a Unix-like operating system and is the best example of open source development and free software; generally all underlying Linux source code can be modified, redistributed and used freely by anyone. Red Hat Enterprise Linux 5.2 is the latest version of Linux operating system.

As we all know every operating system has its demerits or failures and can give errors at any time with out any prior information. There are some common error messages faced by Linux users while using this operating system. Some of the most common ones are the following:

  • Unknown terminal type Linux.
  • Unrecognized option '-m486'.
  • bdflush not running
  • cannot read table of mounted file systems
  • Unknown terminal type Linux.
  • Cannot initialize drive XYZ?
  • EPERM Operation not permitted.
  • Unrecognized option '-m486'.
  • Modprobe can't locate module, ``XXX,'' and similar messages.
  • Mounting unchecked file system.
  • EINTR Interrupted system call.
In most the situations given above a user faces any of the mentioned problems, it becomes difficult for him/her to access or manage his data. He/she won’t be able to do normal tasks which can otherwise be performed effortlessly. If the data which has been rendered inaccessible is important then it becomes essential to recover that data as soon as possible. In this case, he/she would need the help of data recovery software.


Linux Data Recovery Software is an ultimate way out for all Linux related data recovery problems. It also recovers data from formatted hard drives also where file systems have been changed. It recovers lost logical drives and data from physical disk or any removable media.

Stellar Phoenix Linux Recovery software provides data recovery from Ext2, Ext2 and Reiser FS file systems of Linux operating system.
