Sometimes, when you try to access a file or folder in your Linux based computer, you may get the following error message:"Cannot read table of mounted file systems"After this error message, the particular file or folder can't be accessed from your computer.CauseThis error message occurs due to corruption or deletion of etc/mtab or root directory files. These files can get corrupted or deleted when your file system mounts.The process of including a file system into existing directory structure is called file system mounting. File system mounting associates it with a directory in the existing file system structure. Without mounting, the files stored on Linux hard drive can't be accessed by the operating system.ResolutionTo fix this issue, you need to reinstall your operating system. Reinstalling the operating system is never safe as it requires the formatting of the primary volume of Linux hard drive and wipes all the data stored on it. In these circumstances, the things can go wrong if you have stored all of your important data on the primary partition only or you haven't partitioned the hard drive.In these cases, it becomes necessary to recover the data if your data was very important for you and your business. You can perform this task with the help of data recovery software known as Linux recovery.Linux data recovery software are the data recovery tools designed to recover the lost data from Linux hard drive.

Dual boot is the process of running more than one operating system on a single computer system and the system on which dual boot has been applied is called dual boot system. Dual boot system can have two or more different operating system on different hard drive partitions. For each operating system, the partition on which it is stored is primary partition. This is a very helpful and easy method for the users who want to run more than one operating system on the same PC or they want to use some kind of application that specially run on a particular operating system. But there are some situations where if any problem to the one operating system occurs, other operating system will also get affected. This problem generally occurs with a system on which you are running Windows and Linux operating system. When you perform a reinstall of the Windows operating system, you may find that Linux operating system won't work. In this process, the general problem occurs that the file sy stem and boot loader of the Linux operating system get corrupted and it can't boot up. In these situations you need to format the particular partition and reinstall the operating system. Reinstalling the operating system is an easy to perform task that can solve all of your operating system and file system corruption related problems.

Linux - the operating system for a GNU (pronounced Gnew) generation. It has been dubbed the alternative to Microsoft, the solution to all life's problems and many other things that may or may not be true. But what is Linux, and should you care?

To answer the first question, it's a free operating system that looks and acts very much like Unix. You can download it off the Net for free, or you can copy it legally from a friend - although this might take all the fun out of using that CD-Writer you've got and never use for anything, except to brag about it to your friends.

Alternatively, you can buy it nicely packaged from an Internet store and get it delivered with a book about Linux, (Linux Unleashed).

Distributors charge not for the operating system itself, but for their time in packaging and presenting it. Two popular flavors of Linux are Free BSD and Ubuntu. These offer the same basic systems with a few slight differences that can lead to long and entertaining godly wars between supporters of each.

If you're getting into Linux for the first time, Ubuntu is a good bet. You can either go for Ubuntu Desktop which comes with a GUI, or you can opt for Ubuntu Server if you planning to host websites of your own. The server edition has no GUI, but you can install KDE or Gnome to make your life easier. Most of your configuration will be done via the Terminal and you will have to learn a lot of Linux commands.

Linux is more complicated, and it depends on the kind of person you are. If you're the type of computer user who wants every application to run straight out of the box and your system to just do what it's told and run your games, then stick with Windows. But if you're a pioneering soul who wants to find out more about your system and tweak it to perform to the max, then Linux is definitely worth a try.

If you want rock-solid Internet access, if you want to support the development of free software and more efficient solutions, or if you're just the type of person who needs control over every aspect of your life including how your machine performs, then you're definitely a Linux candidate. Linux is perfectly suited to students, developers and just about anyone who wants to try something other than the norm. Newcomers will find support straight off the Internet from thousands of kindred spirits.

It's worth a try - maybe you'll discover a Whole New World of fun and adventure. Or maybe you'll just take it straight off your machine and go back to Windows. However, if you planning to try it out, then load it on that old machine that's just lying around in the basement. You don't need powerful processors and hardware - the most important component is memory. If you have 512mb and a 20gig hard drive then you should be OK. You should be able to run all your applications including your websites with ease. Remember, you will need a permanent connection to the Internet if you going to host your own websites. The best part is that you don't need any antivirus and antispyware software if you're running Linux. Every would-be-virus-writer out there has only one target in mind - Microsoft Windows.

Whether you stick with Linux or not, you'll have come out of your safety zone and taken a trip to the cutting edge of computer technology.

The following error message in Linux operating system may annoy you when you run the fsck command with the sudden fear of losing the precious data:"The filesystem size (according to the superblock) is xxxThe physical size of the device is xxxEither the superblock or the partition table is likely to be corrupt!"The superblock is the important data structure of Linux file systems which describes the size of the inode-table and the size of the total file system. This also contains the information like File system type, size, status, information about the metadata structures. Thus this shows that the loss of either information may create serious problems of data loss in Linux.The problem could be if some files have been attempted to write upon the portion of the disk where the superblock is stored and the filesystem wouldn't allow it to write. The solution of the problem runs in three steps:1. Unmount all the partitions using the 'unmount-a' command in single user mode2. Repai r the partitions 3. Resize the partitionsResizing the partitions without repairing them may complicate the problem with the following error message:"attempt to read block from filesystem resulted in short read while trying to resize"So this is advised to repair the partitions first using e2fsck -cc /dev/md3 command. The process is safe if you have the backup copy of the data and if you don't have, you certainly require tool for Linux recovery.Resizing the partitions would delete all your data, thus the perfect scanning procedure to scan the hard drive and hence Linux data recovery software is required. These are the tools are built with the indigenous technology to run the powerful algorithms.Developed by different data recovery companies, these software allow the users to work through the interactive interface. These data recovery Linux software address all data loss problems Stellar Phoenix Linux Data Recovery software is the superbly built Linux recovery tool for Ext2, E xt3 and Reiser FS file systems. This software uses the extensive scanning algorithms oriented to complete data recovery Linux. The software supports all the Linux flavors for Linux data recovery.You can apply this utility after any instance of data loss. This software offers you the graphically rich user interface which can be checked through its demo version, available on Stellar's website.

The landscape of Operating System is a battle zone with so many opponents in the scenario. The users have so many choices to select from Windows Vista, Leopard and various distributions of Linux.

It is been approximately two years since Vista is out in market but it still do not enjoy the market share what XP used to. Installing it and working with it puts an extra pressure on your pocket. But with so many cheap (almost free) distributions of Linux you can better choose it against Vista. The article will list various reasons:

Updates at Single Click: To make the latest security patches and fix the flaws one has to look multiple places for software and hardware update. To update the Windows operating system, Microsoft update is a good solution. But it is not a complete package. To update Adobe suite, user have to visit Adobe web site. Also to update the drivers, one has to visit hardware vendors. Contrast to this, update process of Linux is simple. The update package includes everything -the operating system, applications, support libraries, hardware drivers. All new versions are looked for and updated at one go.

Also the Linux update process is more efficient than Microsoft update.

Sit Back and Enjoy PC: With Windows your PC can not look after itself. You have to always worry about its efficiency and take those extra pains to make it run efficiently and more smoothly. But Linux is really a boon at this worth cribbing stage. With Linux you do not have to worry for defragmentation of your PC. In crux, you can lay back and enjoy the smooth computing experience of your machine with Linux.

Windows try to locate files nearer to hard drive, which create gaps when users edit those files. When new files are created they fit themselves into those vacant gaps thus get fragmented. As this process goes on the performance of the PC degrades, thus making user to feel the need of defragmenting the PC. Contrary to this, Linux is designed for multi tasking thus addressing this problem at very initial stage.

Cost free PC: Using proprietary software means paying a hell lot of amount. If using pirated copies you are breaking law. But originals are so costly that one would love to cheat rather than paying for the efforts of developers. If you are using Linux, then you do not have to worry about any such issues. You can use a full PC with no costs. With paid software you can not install it without paying for the additional machine but while using Linux this is not the case. You can create as many copies of the operating system and install it on any number of machine without thinking even twice or complaining for any cost issue. Even products like Open Office (rival to MS-Office), image editing programs like the GIMP are available for free. The free programs are by no means a compromise to quality.

No anti virus required: Linux is the safest operating system. No doubt Windows marketed Vista as the most secure operating system but it has many loopholes. Linux is the operating system that allows your PC not to cripple and worry for any anti virus. The reason behind Windows getting frequently affected by virus is the feature that allows users to log in through administrative privileges. Where as in Linux, every user works under a regular user account thus not allowing rogue programs to cause damage.
