Rectifying â€œEither the superblock or the partition table is likely to be corruptâ€Error in Linux
In a Linux computer, partition table and superblock are two most important data structures. The superblock keeps record of the file system characteristics including its size, empty and filled block, location and size of Inode tables, block size and status. The partition tables stores all required information about hard drive primary partitions. When any of these data structure gets damaged, hard drive become inaccessible and all of the stored data can not be accessed. This behavior of Linux operating system results into critical data loss situations. At this point, to retrieve data your data from affected drive, you are required to carry out Linux Data Recovery using appropriate solutions.
In a practical scenario, when you run fsck on Linux hard drive to detect and fix file system errors, you might come across below given error message:
â€œThe file system size (according to the superblock) is xxx
The physical size of the device is xxx
Either the superblock or the partition table is likely to be corrupt!â€
When this error message occurs, fsck scanning process gets terminated and your Linux file system remains in corrupted state. In such situations, you can not access data from Linux hard drive. In order to retrieve lost data, you need to find out the cause of this problem and carry out Data Recovery Linux by sorting it out.
This problem might occur if some files are attempted to write on the portion of hard drive where superblock is stored and file system would not allow it to write.
You can sort out above problem by following three underwritten steps:
Unmount all Linux hard drive volumes using 'unmount -a' command in the single user mode.
Repair the damaged hard drive volumes
Resize the affected Linux volumes.
Resizing the Linux volumes without repairing them might complicate the issue and throw below error:
â€œattempt to read block from file system resulted in short read while trying to resizeâ€
Resizing the hard drive volumes might cause data loss in these situations and require Linux Recovery to be resolved. Recovery in these situations is best possible with the help of efficient third party applications.
These software are known as Linux Data Recovery software. The use high-end scanning mechanism to perform extensive scan of affected drive and retrieve all of the lost data from it. These software are quite safe and easy to use.
Stellar Phoenix Linux Data Recovery is the most excellent solution for all your Linux data loss situations. It supports recovery from Ext4, Ext3, Ext2 system volumes. This software is compatible with all major Linux distributions including Fedora, Debian, RedHat and Ubuntu.
