File system holds all the information about the files located on the hard disk. Without this, your operating system would not be able to locate the data as then no memory pointer would be there. So for any operating system, including Linux, this is the top priority task that file system should remain free from corruption, else to fall for Linux recovery. But while dealing with Linux systems, having Ext2 file system being uses, the following error message may push you in a real critical situation:EXT2-fs error (device 09:00): ext2_check_descriptors: Block bitmap fonot in group (block 3670099)!EXT2-fs: group descriptors corruptedLets come to the Linux file system structure. The Block Group is the components which commutatively create the file system and they create a block group descriptor which is responsible for managing and controlling the file creation and accessing acts. This data structure possesses the Block Bitmap, Super Block, Inode Bitmap and Inode Table like infor mation, which plays the significant role in Linux file systems.Now as the use of this data structure becomes more, its components drift towards corruption and hence giving rise to file system corruption too. In this specific error message, Block bitmap has got corrupted, which acts as the map of the entire blocks in the group. If you will run fsck in this case, perhaps the error messages, stating the corruption in superblock may also be found, firming your belief that EXT2 has got corrupted harshly.If you can locate and then run fsck with the alternate data structures, then you have a chance of Linux data recovery without any pain or else refresh the copy of the file system. But With the second option, be ready to lose all your data. Fortunately, third party data recovery Linux can help you in this regard. These are the software which are designed to run a through scanning mechanism over the hard drive to offer the best Linux recovery results.Through their interactive inter face, these will help you use the Linux data recovery utilities without any problem. For avoiding any flaw in Linux recovery, this would be better if you make a good research prior.Stellar Phoenix Linux Data Recovery software is the application, which proves as the best data recovery Linux help to the users. Its supportive nature to Ext2, Ext3 and ReiserFS file systems and identification power to all type of file make this Linux recovery utility up to mark.Moreover, you would find an interactive interface to work with. This Linux data recovery tool is the ultimate one to solve all the data loss problems.
