Block Group Descriptor Loss Of Information For Linux

Is widely used and Ext2 file system powerful Linux operating system. That provides security, reliability and data management. Space on ext2 filesystem is divided into blocks, and succeeded in block groups, corresponding to groups of cylinders UFS (Unix File System). Groups Each block contains a data structure that describes, known as block group descriptors. However, in cases of corruption to the DMO, it may corrupt system files and data loss in Linux. In such circumstances, you should opt for Linux solutions data recovery to recover your valuable data back.

Access to the file system in the description of the block to reduce external fragmentation and minimizing the number of disk seeks when reading a lot of sequential data. Each block group can be a copy of the block group descriptor table and the super block. All block groups are as follows:



- Block Bitmap


- Inode bitmap


- Super Block


- Inode Table


- Data Blocks


The group descriptor block contains the location of the block bitmap, inode bitmap and inode table start for each BG and they are stored in the handle table group. This creates a copy of BG descriptor, except for components used by the operating system and file system to access data from Linux hard drive.


Due to the increased use and complexity of BMD is a good chance of failure. In some situations, when trying to access any file or directory on the hard drive in Linux, you may experience one of the error message:


- "Input file inode was deleted"


- "File not found"


- "File not available <filename> '


An error message because of corruption, BGD. Corruption can occur due to various reasons, such as a log file deletion, virus infection and software conflicts. In this case, the operating system can not find the required files, and then save the information you come across. At this point, Linux recovery is a critical need to get the data back.


Linux Data Recovery is the best way possible with the help of powerful third-party applications and advanced in third place, known as recovery software for Ext2. They use effective scanning techniques to carry out a thorough analysis of all storage media and retrieve all the lost and inaccessible files lost it.


Stellar Phoenix Linux Data Recovery is the most impressive application to retrieve the data from all possible data loss situations. Returns information about ext4, ext3, ext2, FAT16 and FAT32 file system volumes. The software works well with all major Linux distributions including Red Hat, SuSE, Debian and Fedora.
