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)

Linux Recovery - Tips & Tricks

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: Mount Fails and Can’t Read Mounted File Systems Table

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 w... (more)

Linux Kernel Image Not Found

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 u... (more)

Stop Error “0x0000C1F5” May Cause Partition Loss in Windows Vista

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)
