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:...

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"...

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...

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-

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:

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"...

'Undelete' is an option to recover and restore the lost or deleted files form the computer by rewinding the operation. Without the in-built undelete feature, the retrieval of lost or deleted files is termed as data recovery and in Linux operating system based computers, it is popularly known as Linux data recovery.
There are many file systems, which have the built-in undelete feature to reverse an accidental-delete operation of important data. However, this feature is not available with every file system. Moreover, though the undelete feature is very much useful for the ones who have deleted some important files/folders and at the very next moment, realize that the data was extremely important to be recovered back, the feature also alarms for a security risk...

In case of a Linux operating system based computer, sometimes, the system fails to boot following any unsystematic system shut down. The reason can be anything from a possible file system corruption to an operating system malfunction, but at the end of everything, it is your valuable data in the drive, that has been inaccessible and you need to run any Linux data recovery software to recover them back.
Boot errors are always critical, as once you encounter those errors, your system fails to boot further resulting in the complete inaccessibility of your precious data in the drive. In a Linux system, there are many types of boot errors which may put you in trouble, one of them may be read as below:
"Creating Root Device
mounting root filesystem
(scsi:0:0:0:0) CRC error during data-in phase
(scsi:0:0:0:0) CRC error in intermediate CRC packet
scsi: aborting command due to timeout: pid 0, scsi 0, channel 0, id 0, lun 0 read (10)......"...

With technological advancement, now you can install and use more than one operating system in a single computer. This type of configuration, which is known as dual-boot, offers you to enjoy the features of multiple operating systems. However, sometimes, while making dual boot systems with different Linux operating systems the metadata structure gets corrupted. This kind of corruption results in the loss or inaccessibility of your valuable data and the need for advanced Linux data recovery arises to recover the data back.
In order to configure your system as dual-boot with another flavor of Linux, you are trying to install Fedora Core and come around a threatening error message. The error can be read as below:
"The partition table on device is corrupted. To create new partitions it must be initialized, causing the loss of all data on this drive"...

Most of the Linux operating systems are open source applications and are regularly modified in order to safe-guard the system against any new threat in the form of viruses, malwares or other technical drawbacks. An user can witness new changes and improvements in Linux almost every day. In spite of all the good things, still there are occasions, which lead to the loss or inaccessibility of valuable data from your Linux system. Among such instances of data loss, hard drive crash is one. Hard drive of your system contains many important data of yours' and anything like a crash of it can be an obvious hue and cry. However, with the help of advanced Linux data recovery, all your seemingly lost data can be recovered back.
When the hard drive crashes, though the data in the hard drive exists, you are unable to access the same. Apart from any physical damage, there can be many other problems behind the crashing of your hard drive, such as corruption of the file system, virus/malware infection, accidental deletion of the system files, operating system malfunction, other application contradictions etc. In any of these situations you may come across the following symptoms, which may signal a possible hard drive crash:...

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':...
