Moreover, the blocks are managed in block teams and all of the details about every block group is outlined within the Group Descriptor. Furthermore, the knowledge is listed within the group descriptor desk. In case, if the block group descriptors get broken, the entire Linux system turns into inaccessible and it’s important to run any Linux information restoration software program to get better the information again.
Within the conditions, when the group descriptor desk has been corrupted, you could encounter error messages suggesting the identical, following which the Linux system fails in addition. The error message might learn as beneath:
