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)

Bad File Descriptor Error in Linux

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... (more)

Unsuccessful Rollback Phase Cause Partition Loss in Microsoft Windows

Microsoft Developer on Ulitzer Several users upgrade their operating systems from Microsoft Windows XP to Windows Vista. But in case if any error during the setup process, rollback phase is initiated. When you run the rollback phase, your system returns to previous installation of Microsoft Windows operating system. But there is no guarantee of rollback phase to be successful. When it does not complete, no operating system can run properly and thus all hard drive partitions become inaccessible. In such situations, Partition Recovery is required to get your valuable data back. When... (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 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)
