Though it may be that much friendly for the user, but LINUX is more secure and organized in terms of functionality. In LINUX, you don't get everything preloaded and there is a command for every action in it. Here, there lies a big hierarchy of files and the 'mount' command tells the operating system that a file system is ready to use and associates it with a particular point in the system's file system hierarchy.

Sometimes, the mount command does not work and thus the drive can not be accessed. The cause may be the corruption to the Linux file system and It results in critical data loss. To fix up these issues, power packed Linux hard drive recovery are the only answer.

'fsck' command is used to check the consistency of a file. Trying 'fsck' command after failing to mount, you may receive an error message.

The Error message may read like the following:

"[/dev/mapper]fsck -a /dev/mapper/mpath0p1fsck 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 ext2file system. If the device is valid and it really contains an ext2file system (and not swap or ufs or something else), then the superblockis corrupt, and you might try running e2fsck with an alternate superblock:e2fsck -b 8193 "

Explanation:

When you try to resolve a file system corruption problem and mount the hard drive while using fsck command, you may get the error message indicating that the file system is inconsistent. Such circumstances lead to the failure of LINUX recovery using fsck command, and your data will remain inaccessible.

Resolution:

Boot the system in single user mode and Unmount the drives.

Check for the presence of file system, if not, apply fsck on raw drive.

If the above fails, only through LINUX recovery software, your data can be brought back. These applications incorporate high-end scanning techniques to ensure safe and successful recovery. With a friendly user interface, these tools are a boon to users who don't have prior technical knowledge on the same.

Stellar Phoenix Linux Data Recovery is one of the robust as yet easy to use LINUX data recovery tools. This efficient software supports recovery from all Ext4, Ext3, Ext2 and ReiserFS file system volumes and is compatible with most of the popular flavors of LINUX available in the market.
