Warning Message in EXT2 File System: Mounting Unchecked File System

We can visualize file system as a tree, rooted, as it were, at /. /dev, /usr, and the other directories in the root directory are branches, which may have their own branches, such as /usr/local, and so on. File system is a process or organizing or arranging data in pc or stored files. In windows we just install the softwares for specific hardware and it works fine.

But when we use Linux or Unix Operating system, we have to mount every drive for accessing it. These OS assign a device name to each device, but this is not how the files on that device are accessed. Instead, to gain access to files on another device, you must inform the OS where in the directory tree you would like those files to appear. This process is called mounting a file system.

During boot process file system automatically mounted. For mounting a file system, we use command like # mount device mountpoint. If we are using Linux operating system and we are trying to write a CD or ISO files in CD we get following error:

“Mounting unchecked files system, running fsck is recommended”

This error may come when your drive is not supporting bootable CD or there is data corruption in Linux operating system and cause dirty flag in drive volume. One more reason is possible is virus attack or improper shutdown. All scenario result is critically data corruption and loss of your precious data.

On normal shutdowns, like for shutdown -r or -h, this *should happen. However, if some process is running that refuses to die prevents a clean unmount, then the meta-data for the file system may not be written to the disk. There is a “marker” in the file system that shows that the file system is mounted. This is then left “unclean” and on reboot the system will detect this and run (e2)fsck to try and assure no corruption propagates and further damages the file system.

In this situation you will face a serious data loss and your will need a powerful Linux Recovery utility which can recover your data. But you must have some precaution If you’re getting this error such as “don’t try to check unmounted file system”. Arrange to mount root file system in read only mode at startup, if you need then after this operation remount it in read/write mode. Now run the program FSCK which may repair the file.

If it doesn’t help use Stellar Phoenix Linux Recovery software which recover and repair your files stored in hard disk so that you didn’t get this error and again. This Linux data recovery software is a best prevention for serious data loss. This software is compatible with all flavors of Linux including Red Hat, SUSE, and Ubuntu. It is special data recovery tools that can help you in recovering your lost data from Linux hard drive in cases where data has been lost due to File system corruption or deletion, accidental deletion, missing logical volume, virus attack or operating system corruption.

Cause of File System Corruption in Slax-Improper Use of USB Key

Data Loss Issues or File System Corruption in Slax Due to Improper Use of USB Key

Slax is a modern, portable, small and fast Linux operating system with a modular approach and outstanding design. Slax 6 is offered in a single version, and completely relies on modules (additional packages) for extra features. Slax in Linux CD based or USB based operation system which we don’t need to install. We can use it using CD or USB. It totally depend on it modules. If we don’t have text editor or image editor then not to worry because we can download modules or additional packages called Slackware. No need to install these packages, just copy it and run from destination.

Slax has small size but it gives a wide range of softwares and pre installed additional software packages which make our work quite easy. Best feature is that it’s free for everyone. Slax works faster if we are using USB over CD. But if we are using old version then it might be slow because it takes time to read from old devices. Use of right USB key, you can make your work faster. One more beneficial feature of Slax is it is predisposed with own recovery tool, so in case of data loss you can recover data using this tool.

Even it has lots of good feature but sometime accidentally data loss happens and we may loose our important data. For this we must have some precaution and must know the common reason for data loss in Slax. Virus attack or accidental deletion of data can leads to data corruption and missing data. Use of wrong USB key or unplugging USB without shut down the Slux may cause data loss or interrupting write operation of Slux. If you don’t took precaution then it can leads from simple data loss to file system corruption. It may possible predisposed Linux recovery software doesn’t able to help you to recover your data. In this situation you need some powerful Linux recovery software which can fix file system corruption and recover your lost data.

You can fix it use of this command “dosfsck -wa /dev/hdb1(Your Partition Name)”. It may helps you and if it doesn’t help you then try Stellar Phoenix Data Recovery Linux utility which will definitely recover your data or partition and fix file system corruption issues. This software works on advance algorithm to fix the errors, it scan boot sector and bad sector of hard disk and recovers data from that portion of hard disk. This recovery Software recovers lost files or folders from damaged or corrupt Linux Ext2, Ext3 and Reiser FS volumes.
