Causes of Corruption in the Linux Block Group Descriptor
Linux has become one of the most reliable operating systems in the digital world. Yet, like other operating systems, it is likely that a user’s Linux volume may get deleted, and the user may encounter data loss. In cases of disk failure, virus attack, power surges, accidental deletion of partition, software conflict, inaccessibility of the hard drive by the operating system, or registry file deletion, one encounters data loss. Apart from that there are various reasons that may directly or indirectly lead to data loss. In such a situation, you have little option but to opt for Linux Recovery using backup, to ensure that your working is not hampered. However, in case the backup is unavailable, not-updated, or non-working, then you need to opt for Linux data recovery solutions.
Consider for example that you try to access some data file using Linux partition, and instead of the file opening in front of you, following message greets you:
File is inaccessible
File not found
Inode entry of the file is deleted
These errors are a result of corruption or deletion of a data structure which control and manage various file creation and access activities. This data structure is known as Block Group Descriptor, and stores information super block, block bitmap, inode bitmap and inode table. The Block Group Descriptor is used very frequently by the file system and the operating system, its corruption can lead to the operating system failure in accessing the specified files. This causes data loss in Linux.
However, with a clean and updated backup in place, it is not a difficult problem to handle. But in case the backup is absent, non-working,or not-updated, then data loss is unavoidable.
To recover data in such a case, one has to opt for third party Linux data recovery software. These are tools that recover data from Ext2, Ext3, Ext4, and FAT file system volumes. Recovery is performed for all sorts of office files, photos, videos, audios, and BKF files, by applying complex algorithms. Good Linux recovery tools performs recovery from all distributions of Linux, including, Caldera, Debian, Gentoo, Mandrake, Red Hat, Slackware Sorcerer, SUSE, and TurboLinux.
Stellar Phoenix Linux Data Recovery is a bankable utility for data recovery Linux operating system. With various recovery options including drive cloning, imaging, save scan and resume recovery; and a graphical user interface, this tool is very user-friendly. With read only conduct, and compatibility with Windows 7, Vista, 2003, XP and 2000 operating system the tool ensures comprehensive recovery of all data.
