Linux has gained enough popularity for its new and updated features. Usually, this operating system is considered as the most regularly upgraded application and hence, with Linux, many users feel that they are having the advantage of using the most recent technologies. Even some feel that Linux is free from virus attack and other data loss problems. However, it is the fact that the technology has nothing to do with data loss. Linux systems also undergo severe data loss situations, leaving the system drive completely inaccessible. Under such cases, you can take the help of any Linux data recovery software to retrieve your data back.
Data loss in Linux can be in any form, starting from the accidental/intentional deletion, formatting of the media, virus/malware attack, operating system malfunction, file system corruption or any other software/hardware contradiction etc...

File system is a very important part of a Linux system. This is a method of organizing data in the storage media of the computer system. All the information about files is stored in the file system. The operating system learns about them from the file system and then, we able to access them. Sometimes, while working on your Linux computer, if power goes away and the system shuts down improperly, there occurs some sort of corruption to the file system. There may be some other reasons behind a possible file system corruption in a Linux OS based system, such as virus/ malware infection, serious application contradiction, OS malfunction etc. Corruption or damage to the file system results in the inaccessibility of your valuable data in the media and you need any Linux partition recovery utility to get the data back.
In case of file system corruption issues, you may encounter some error messages on the screen. The error message that you may have received can be as below:...

Every computer operating system performs various system level operations during boot time or while executing installed applications. These operations are critical from system point of view to access data from hard drive and run the software, both application and system software. Linux operating system manages all the system related operations through init. It is the most significant step of booting process. However, if it fails to run properly, system becomes unbootable and stored data become inaccessible. This behavior leads to data loss and put you in need of Linux data recovery solutions.
When you boot your Linux computer, init is the step of the process that is identified through process id 1. The init data structure has all controls sequences and processes when you shut down your Linux machine. If you encounter errors while starting or shutting down the Linux system, it can be due to missing init file or initrd file corruption...

Linux is a widely used open-source operating system, which has various distributions to meet different kinds of needs. This advanced operating system supports a wide range of file systems, including Ext4, Ext3, and Ext2. Among all Linux file system, Ext3 is the most popular one. It is used as a default file system numerous Linux versions. It is stable and powerful, which provides a wide range of safety measures to prevent files damage and need of Linux data recovery solutions.
Ext3 does not require file system checking when your Linux computer shuts down unexpectedly because of power failure, operating system crash, or any other reason. Ext3 also enables H-Tree indexing and online file growth for large directories. However, irrespective of various advanced security features, this file system may encounter corruption in some situations.
As a practical instance of Ext3 corruption, you may encounter the following error message with your Linux system-
"fsck.ext3 Unable to resolve 'LABEL=boot"...

In a Linux operating system based computer, directories, blocks, sockets, files, and other items are referred by their corresponding file descriptors. File descriptor is one of the significant data structures of Linux operating system. It is very essential for the file descriptor to be consistent for proper working of your system. In case it is damaged, you can not access your precious data from the disk and face severe data loss situations. In such cases, you need to opt for Linux data recovery solutions.
If you encounter any error from your system related to file descriptor corruption, it can be due to corruption to the Linux file system. File system corruption is a major reason of data loss and cause serious problems for you. For a practical instance of this problem with your Linux system, you may encounter the following error message when you attempt to access data from your Linux hard drive-
“Bad file descriptor”...

These days, many users are switching their operating systems from Windows to Linux. Even, some are opting for a dual boot system by installing Linux alongside Windows to use a bit closely before completely migrating to Linux. The reason is pretty simple. Linux is new and with various new features. Apart from this, the operating system is undoubtedly the most frequently updated operating system than that of its other counterparts. But, one thing is quite true that no operating system is entirely free from any loose holes. Moreover, if it is not right to term it as loose hole, still, there are instances when the OS failed to match with the user expectations. Among such troubled occasions, Linux data recovery applications can be immensely useful in recovering your valuable data back.
You may encounter a number of instances of data loss in your Linux system. The reason can be a simple data deletion to harsh system crash. Some of the mostly encountered Linux data loss situations are listed as below:...

Linux operating system supports dual-boot technique and thus lets you install another operating system on the same machine. This method is helpful if you need to use features of two operating systems. However, in some situations, this arrangement may make your system unbootable and inaccessible. This behavior makes your significant data inaccessible and lead to data loss. In such situations, you need to use Linux data recovery solutions to get your precious data recovered.
When you start your Linux machine, the very first thing that occurs is hardware initialization. After this, GRUB loads from Master Boot Record (MBR) of hard disk based on the configuration.
You may see boot menu showing all operating system in the list from that you can start system or initialize Linux kernel. In case you do not observe such behavior, the problem can be related to MBR or GRUB. In such situations, you may need to format the disk and perform data recovery Linux.In a practical scenario, you may fail to boot your Linux based computer when you install the Windows operating system on the same machine. This behavior makes all your precious data inaccessible from Linux disk...

Linux is an open-source operating system, which is widely used by home as well as professional computer users. It is a reliable and stable operating system because of the features that it offers. However, there are some situations, where your Linux hard drive may become inaccessible due to file system inconsistencies. This behavior leads to severe data loss and you need to use advanced Linux data recovery solutions to get your valuable data back.
There are numerous reasons of inconsistencies, which include improper system shutdown, virus infection, system data structure corruption, and operating system malfunction. This behavior of Linux can cause critical problems of data loss. For instance, you may encounter the following error while trying to access data from Linux hard drive-
"/dev/sda5: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY
(i.e., without -a or -p options)"
You encounter this error message when you attempt to fix the file system problems using fsck command. In order to perform data recovery Linux in such situations, you need to identify the root of this behavior...

While working with our favorite Linux system, everyday we write, edit, save and delete several data on the system hard drive. Many users take hard drive of the computer as a permanent storage means or a place to store data before the day-end backup process. However, apart from strong firewalls, anti-virus software and other methods of data safety, we may never guaranty that we will not face any instance of data loss in our system. Therefore, incidences like accidental deletion, virus/malware infection or file system corruption etc. can knock at our door at any time. Moreover, be it knowingly or without being able to solve the problem we sometime format the hard drive leaving our data in absolute lurch. Under all such tragic instances of data loss, Linux data recovery can help you recover your lost data back...

In computing, Partition is a part of hard drive that works as a different disk and has a separate file system. Disk partitioning is usually done for better management of stored data and to ensure safety of valuable data in case of operating system malfunction. However, there are some circumstances where you need to remove the Linux hard drive partitions/volumes. This behavior removes all the data stored on deleted partitions and lead to severe data loss. At this point, you are required to opt for Linux data recovery to extract your significant data.
Linux operating system supports a number of hard drive partitioning tools, such as parted (GNU General Public License partition editor), fdisk, sfdisk (command based version of fdisk), and cfdisk (curse based fdisk version). Sometimes, while performing basic maintenance of the boot partition or primary partition of Linux hard drive, you might encounter an error message similar to the following one:...

In the Linux system, the 'mount' command is used to enable the partitions. Moreover, with the 'mount' command, the Linux OS is triggered to avail the data and information of the particular partition to be accessed. However, sometimes, the command fails to mount the partition and following which, all the data in that particular drive becomes completely inaccessible. The cause may be a possible corruption to the file system of the Linux system and you can use any Linux recovery software to recover back the data.
Sensing a file system based error, if you run the 'fsck' utility to mount, you may come across the below error messages:
"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...

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."...

Like other computer operating systems, Linux also uses a number of data structures to perform various operations. These data structures include Superblock, root directory. Superblock is one of the most significant data structures, which contains all the basic information, such as file system type, status (either mounted or un-mounted), and size. In some situations, this data structure may get damaged and Linux cannot access data from hard drive. It causes critical data loss situations and requires Linux data recovery to be fixed.
Linux file system manager accesses the Superblock information for maintaining it. All the parameters, like size, defined in the Superblock must match the actual parameters; otherwise you may face critical problems. For example, if the size of is different in Superblock as compared to actual size, then disk is reported as corrupt and you run across critical data loss problem and need to opt for Linux recovery solutions...

Linux is a popular open source UNIX-like operating system that organizes all your files in a tree structure. All the files are rooted at '/' or root directory. In order to attach any file system of other drive to file tree, you are required to mount the drive. You can mount Linux drive using mount command. However, in some cases, the mount command fails to mount the drive and makes it ready for use. It makes your significant data inaccessible and causes serious data loss situations. To recover Linux data in such cases, Linux data recovery becomes need of hour.
You might fail to mount a Linux hard drive is the file system of the disk is corrupt. File system corruption may take place due to numerous reasons, ranging from virus infection to hard drive crash. In a practical scenario of this problem, you may encounter the below error message when you try to mount a Linux hard drive
Using mount command:
"mount: you must specify the filesystem type"...

The Linux hard drive is partitioned in various partitions/volumes for effective management of your valuable data. Linux hard drive volumes start from the boot block where boot information of the operating system is stored. Last two byes of the Linux boot block contains boot block signature. In some cases, operating system cannot locate boot block signature and the disk cannot be accessed. It makes your significant data inaccessible and leads to data loss. Such cases require you to either restore data from backup or use Linux data recovery software to scan the drive and extract data from it.
For example, you might encounter an error message similar to the following one when you attempt to boot a Linux operating system based computer-
"Master boot record on /dev/hda has been updated."
Subsequent to the above error, you may also encounter further error message that states-
"No boot signature found on partition"...

Though the Linux operating system is considered as very much advanced and is most frequently updated, still data loss situations do happen in Linux systems resulting in the loss or inaccessibility of important data. In such situations, if you do have another copy of your data, then only you can feel relieved. Among many other techniques to safe guard your data, hard disk mirroring is one such technique, through which you can be able to create an exact copy of your hard disk. 'Ivconvert' is an in-built utility in Linux operating system, which is meant to convert the linear logical hard disk volume to an exact or mirror logical volume. However, the point of caution is that if you do not handle the process carefully, it can lead to the failure of your hard disk and data loss thereof. Under such a condition, you need to take the help of any Linux data recovery software to bring back your lost or inaccessible data.
A brief about 'Ivconvert':...

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...

Linux operating system has been invented long ago, There has been various new additions as well as up-gradations to the previous versions of Linux and the development of Ext3 is one such example of the betterment of the operating system. Ext3 or the third extended file system is a journaled file system and has been developed over Ext2. With many advanced features, Ext3, still lacks at many grounds, such as unavailability of any data defragmentation tool, accidental deletion causing complex cases of data loss etc. Hence, in case of an accidental deletion, if you do not have a valid backup, you need to take the help of a Linux data recovery utility to recover your seemingly lost data back.
A brief about Ext3 file system:...
