subject: Resolving ext2-fs: Group Descriptors Corrupted Error In Linux [print this page] In Linux operating system, file system stores all of the critical information about files located on the hard drive. Without file system, operating system can not locate files stored on hard drive and thus they can not be accessed.
This is the top priority for an operating system to ensure that file system is intact. It should not be corrupted for proper accessing of data. Otherwise, all of your critical data on the hard drive would become inaccessible and you come across data loss circumstances. At this point, it becomes essential to opt for Linux data recovery to retrieve lost, missing or inaccessible data from your Linux hard drive.
In a practical scenario, when you try to boot your Linux computer that is using Ext2 file system, you might come across below error message:
EXT2-fs error (device 09:00): ext2_check_descriptors: Block bitmap form not in group (block 3670099)!
EXT2-fs: group descriptors corrupted
In Ext2 file system, Block Groups are the critical components that commutatively create file system and design block group descriptor that is responsible for controlling and managing file creation and accessing tasks. This significant data structure possesses Super Block, Block Bitmap, Inode Table and Inode Bitmap like information that plays a very critical role for Linux data accessing. In case of corruption to these data structures, you need data recovery linux to salvage data from your Linux hard drive.
Root of the problem
This behavior of Linux operating system occurs due to corruption to the block bitmap. Block bitmap works as a map of all the blocks in group. If you run fsck in this situation, you encounter corruption error message, which states that your file system is harshly damaged.
If you manage to locate the damaged data structure and can replace it with alternative one, you can make your system functional. But this method does not help you to recover your data. To retrieve valuable data from hard drive, Linux Recovery is required.
Recovery is best possible using third party Linux data recovery software. The applications are capable of methodically scanning affected Linux hard drive and extract all of the lost data from it. These tools are completely easy to use as they have interactive and simple graphical user interface. With non-destructive conduct, the applications never alter original data on the hard drive.
Stellar Phoenix Linux Data Recovery is the best ever made and the most effective application for absolute recovery. It work well with all major distributions of Linux operating system. The application recovers all lost, missing or inaccessible data from Ext4, Ext3, Ext2 and ReiserFS file system volumes.
