Description
In Linux operating system, the file system stores all critical information about files located on hard drive. Without file system, operating system can not located and access data from the hard drive as the operating system accesses file system pointer to locate data.
In a practical scenario, while dealing with Ext2 file system of Linux operating system, you may come across below error message:
“EXT2-fs error (device 09:00): ext2_check_descriptors: Block bitmap fo
not in group (block 3670099)!
EXT2-fs: group descriptors corrupted”
After this error message, you can not access data from the drive and your system may possibly can not boot up. In order to fix this issue, you have to find out the its cause and perform Data Recovery Linux by fixing it.
Root of the problem
The Ext2 file system is made of several Block Groups that create block group descriptor, which is responsible for controlling and managing files creation and file access operations. This metadata structure has Block Bitmap, Inode Bitmap, Inode Table, and Super Block like information that are most critical components of Linux file system.
Resolution
There are two possible fixes of this problem:
1) Locate and run fsck with alternative metadata structures.
2)Format the hard drive and reinstall operating system to replace damaged file system with new one.
Although, second option is able to sort out all such issues, but also has a downside. It removes all the data from hard drive and cause catastrophic data loss. In such cases, Ext2 Recovery applications are required to handle the situation.
The Linux Data Recovery software are particularly designed to scan the drive using powerful scanning algorithms and extract all lost data from it. They enable you to perform Linux Recovery on you own as of rich graphical user interface. The tools preserve integrity of your data due to read-only and non-destructive behavior.
