fstab and mtab are two important files found on Linux systems.
fstab: The file is also sometimes referred to as file systems table or
/etc/fstab. It is meant to list all the available disk partitions and disks.
It also includes information about how these disks and partitions are
integrated into the file system of Linux. Its corruption sometimes leads to
Linux Data Recovery needs. mtab: Also known as a mounted file systems table,
it enlists mounted file systems. When any file system is mounted using mount
command, the file is automatically edited.
In case the system finds errors with any of these files, probably due to
corruption, the system may fail to mount with the following error:
“Cannot read table of mounted file systems”
Other than file corruption, the reason could be file deletion. When the mount
command is used to mount the file system, it reads fstab file to ... (more)
In a Linux system, files, blocks, directories, sockets and other items are
referred by corresponding file descriptors. If your system is reporting
errors that the file descriptor is bad, one of possible causes is that file
system is corrupt and thus, you require restoring from backup. But if backup
is not valid enough to restore complete information, you need to use advanced
Linux Data Recovery applications.
As an instance, you might encounter the below error message with your Linux
“Bad file descriptor”
You might receive this error while trying to access a file or... (more)

File Indexing is an allegedly useful feature of Microsoft Windows operating
system. It extracts critical information from files on hard disk and creates
the “searchable keyword index” that Is used for making the file search
more efficient. Using file indexing service, you can easily searching for a
phrase, properly or word in a document, even without knowing name of the file
that you want. In some situations, the indexing of file may get damaged and
may access all your files inaccessible from Windows hard drive partition. In
such cases, you need to ... (more)
Partitions created in the hard drive enable you to install different
operating systems. A partition table is positioned at the first sector
(cylinder 0, head 0 and sector 1, Master Boot Record) of every hard drive.
This table contains the information about locations and sizes on the hard
drive. Corruption in a partition table can occur due to improper system
shutdown, file system corruption, software bugs and more. Once the partition
table is corrupted, the user may not be able to boot a particular operating
system. Furthermore, the data saved in the unbootable partition becomes ... (more)
Linux boot process proceeds in steps. At first, BIOS selects the boot device
and loads the boot sector. The boot manager then loads the kernel image in
RAM to execute and run the setup code. Kernel initializes all the installed
devices, switches the CPU from Real Mode to Protected Mode, loads the
compressed kernel and performs further boot process steps. But in case if
system cannot find this kernel image, it will fail to boot.
In such situations, your system either hangs or displays error messages and
eventually, you cannot access your data. Data backup, if present, valid and
