The Linux operating system is supposed to be the most regularly updated operating system among its counterparts. Apart from this fact, for its advanced technology and features, a large number of users prefer Linux. But, in Linux, the user can not get everything preloaded just like Windows. There is an unique command for each operation in Linux and from the long list of regularly used commands, the 'mount' command lets the operating system to learn about the file system and lists in the file system hierarchy of the computer, which lets us access the the particular drives. However, sometimes, the 'mount' command fails to work and the OS can not be able to learn the drives resulting in the inaccessibility of them. In such situations of data loss or inaccessibility, Linux data recovery can help you recover your valuable data back.

There can be a possible file system corruption, which has led this abrupt behavior of the Linux system following the failure of the 'mount' command. The 'fsck' is a built-in command-line utility in Linux operating system, which checks the consistency of the file system and repairs the same, if finds any error. After encountering the above situation, if you try to mount the drives using the 'fsck' command, you may encounter some more error messages. The error messages may be read as below:

"[/dev/mapper]fsck -a /dev/mapper/mpath0p1 fsck 1.35 (28-Feb-2004) ext2fs_check_if_mount: Input/output error while determining whether /dev/mapper/mpath0p1 is mounted."

OR

"fsck.ext2: Bad magic number in super-block while trying to open /dev/mapper/mpath0p1 /dev/mapper/mpath0p1: The superblock could not be read or does not describe a correct ext2 file system. If the device is valid and it really contains an ext2 file system (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 <device>"

The above error messages clearly state that the file system has been corrupted. In order to resolve the issue, you need to boot the Linux system from the safe mode and run the 'fsck' command to repair the corruption. However, if the file system has been severely corrupted, 'fsck' simply exits without doing anything. In such a case, if you are an expert user, you can input the next super-block address or the size of the same to the 'fsck' command, which can help the utility to gather the information from the next super-block and do the job.

However, failing to the above resolution method, you need to opt for any Linux drive recovery software to bring back your precious data.

Stellar Phoenix Linux Data Recovery is an efficient as well as 100% risk-free Linux recovery utility of the current time. The utility has been trusted by a number of users for its power-packed scanning algorithms and ability to recover lost, deleted, formatted or inaccessible data from any troubled Linux drive irrespective of the complexity of the data loss situations.
