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
based system:
“Bad file descriptor”
You might receive this error while trying to access a file or while trying to
boot the system.
Cause
Possible reasons for the ‘Bad file descriptor’ error to occur are:
Linux systems use a special file, called /dev/null (also called the null
device). This file removes all the data that is written to it after reporting
that the write process has succes... (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)
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

Stellar Information Systems Limited, the leading providers of advanced data
recovery software and services, announces an update to its flagship product
of Linux data recovery.
Stellar Phoenix Linux Data Recovery v4.0 now includes support for Ext4 file
system and also an extended support for FAT12, FAT16, and FAT32 file systems.
The update includes disk cloning feature and improves file preview support
for various files. The free demo version of the software is available for
download on Stellar's website.
“With the inclusion of new technologies and support, use of Linux on

Kernel is a critical component of a Windows NT-based operating system. It
sits between Executive and HAL and offers multiprocessor synchronization,
interrupt and thread scheduling and dispatching and execution dispatching and
trap handling. This is also in-charge for initializing the device drivers on
boot-up, which are required to get the Windows up and running. MS Windows
uses kernel-mode drives that allows it to interact with the hardware
resources.
But in some situations, where some kernel files may get damaged or lost,
system may not boot up and all your hard drive partition... (more)
