subject: Disk corruption in LILO results in inaccessible Linux system [print this page] Cause: Cause:
The reason behind this booting problem is that the descriptor table is damaged.
In a Linux system, the hard disk is parted into blocks and then into block groups. The information of these block groups is stored in a group block descriptor, which also acts as an index table for these tables.
Resolution:
In such situations, you can perform the following methods:
1) Check the BIOS (Basic Input/Output System) and verify whether the disk parameters in the disk are correct or not.
2) Try to format the partition again and install the LILO. However, that would mean that the data may get lost.
3) Run the 'fsck' tool to mount the file system and to check and repair any corruption issues on the file system.
4) If the 'fsck' command fails, then perform a complete format of the hard disk.
Now, if the Linux system is still showing corruption systems and you do not have updated backup of the data, then the best solution to recover inaccessible data is to use a professional Linux data recovery software. These Linux recovery tools perform non-destructive scanning algorithms to recover data in few easy steps.
