Are you facing file system structure inconsistency errors? Are you unable to boot your Linux computer? This is due to problems with Linux file system. In such cases, operating system can not get required information to boot and thus you face odd behavior. This behavior renders your entire system inaccessible and unusable. In such circumstances, you may experience horrifying situations of data loss. Data loss is a very critical situation that creates need of Data Recovery Linux.

When you try to start your Linux computer, you may come across any of the below symptoms:

•    You encounter “Error 16: Inconsistent filesystem structure” error message while booting your computer. The system loops round and attempts to boot the system again, with the same error message.

•    When you select previous version of kernel at boot menu, the system starts booting, but runs “Checking filesystems” and does not give any error. However, when it goes to /boot directory, you get “Error reading block 49404 (Attempt to read block from filesystem resulted in short read) while doing inode scan.” error message.

•    You can get into the recovery mode, but can not run system maintenance tool.

•    When you run fsck utility from maintenance prompt, you encounter “short read” error.

If any of the above behaviors occur, you can not boot your system and it becomes inaccessible. In order to get your precious data recovered, Linux Recovery is required.

Cause

The above problem is caused by the Linux file system code for denoting internal error, which is returned by sanity checks of file system structure on hard drive not coping up with what is anticipates. It is generally resulted by a damaged file system or due to bugs in code handling in GRUB boot loader.

Resolution

File system corruption and boot errors call for hard drive formatting and operating system reinstallation. This replaces all the damaged system files and file system. However, it also removes all the data from hard drive and causes severe data loss.

In such events, Linux Data Recovery software come to your rescue. The applications are specifically designed to extensively scan the affected Linux hard drive and retrieve lost data. You need not have sound technical knowledge to perform Linux Recovery using these tools as they have interactive user interface.

Stellar Phoenix Linux Data Recovery software successfully recover lost, deleted, or inaccessible data from Linux hard drive. It supports recovery from Ext4, Ext3, Ext2, FAT12, FAT16, and FAT32 file system volumes. The software works well with all major versions of Linux operating system, such as Ubuntu, Fedora, SUSE, Debian, and Mandriva.

When you bring home a new computer or update an old PC choosing a suitable operating system for your computer may be one critical decision you would have to make. Since operating system is software that allows computer to execute basic functions it is certainly the most vital part of your computer. Therefore, it is evident that you need to carry out a detailed study before you go ahead in choosing an operating system for your PC. If you are a novice it would be advisable to go forth for online operating system support.

In this article we would provide you a brief overview of the major Operating systems, which could possibly help you, make a wide decision.

The major three operating systems are:

Linux Operating System
Mac Operating System
Windows Operating System

Linux Operating System

Linux Operating System was developed by people from all over the world with a common goal of developing a free operating system. Its source code is open and free to anyone. Various programming teams are working for developing Linux Operating System for various purposes. Linux could be a best deal for businesses in which computer systems are required for basic functions. The negative point could be it is unable to use Windows programs. Another drawback is- Linux has no standard edition and since it is free you shall find no legal comebacks if you encounter a problem with the software.

Mac Operating System

Though this operating system is quite stable and works with a lot more programs as compared to Windows it does have its own disadvantages. For a person who has had more experience on Windows, switching to Mac interface would not be easy.

Besides, like Linux this operating system is unable to use Windows programs. Also, there are a few file types that are not easy to open. Another point would be files deleted in Mac OS are overwritten immediately which makes them unable to be recovered.

Windows Operating System

For many home and business users Windows Operating System is the only preferred operating system. Windows has many advantages and possesses almost universal 3rd party programming support. However, there are a large number of bugs discovered in windows and Windows Operating System is more susceptible to viruses as compared to the other systems.

Each operating system has its own pros and cons; the best way to choose one would be to analyse your needs and then go ahead in installing a suitable one. Online manuals could be some help in providing you Operating System Support; however you could use some live help through Online Operating System Support.

There are many organizations which offer you top rate Online Operating System Support service. Their experts would not only help in choosing a good operating system, they would also install the same and provide you result-oriented support whenever you need it.

Modern computers enable you to install two or more operating systems on a single machine and use those operating systems independently. This configuration is known as dual-boot or multi-boot. The most popular combination of dual-boot system is Microsoft Windows and Linux operating systems. In order to continue Linux installation on a Windows machine, you are required to create a /boot partition using the free disk space available on your hard drive. You are highly recommended to halt Linux installation process while creating space for the /boot partition. However, it may render your Windows hard drive partition inaccessible and cause serious partition loss. In such circumstances, you need to go for Partition Recovery Software to retrieve inaccessible and lost hard drive partitions.

In order to illustrate this problem, consider the underwritten scenario:

You use a Microsoft Windows installed machine that has two partitions- one boot partition and one data partition.

You run the Setup of Linux operating system to install it on free hard drive space.

You abort Linux installation process when it creates /boot partition for the Linux operating system.

You boot your computer with Microsoft Windows operating system and find out that your data partitions is not accessible.

Or

You are able to access the data partition, but if you use a tool that accesses information of partitions, it displays wrong information about the Windows partitions.

Root of the problem

The problem generally occurs due to corruption of MBR (Master Boot Record) partition table, when you abort installation process of Linux operating system. Hard drive errors might have been introduced by an interrupted installation of Linux operating system.

Resolution

In order to Recover Partition in such situations, you can try out the below steps:

Remove and recreate the damaged Windows partitions, if you have an updated and valid backup in place.

If the backup is not updated or is unavailable, you can opt for third party applications to recover lost or damaged hard drive partitions.

The Partition Recovery Software are suitable for virtually every partition loss situation in Microsoft Windows. They deploy advanced scanning techniques to efficiently handle partition loss and ensure absolute Windows Data Recovery. With simple and rich graphical user interface and non-destructive nature, these applications are totally easy and safe to use.

Stellar Data Recovery Software recovers lost, corrupted, damaged, inaccessible, or deleted Windows partitions. The software is designed for Microsoft Windows 7, Vista, 2003, XP, and 2000 operating systems. It salvages NTFS5, NTFS, FAT32, VFAT, FAT16, and FAT12 file system partitions.

If you have taken the time to read my bio you will notice that I’m biased towards the belief that computer operating systems should be inexpensive or even better free. Several years ago I stumbled upon Unix while working out in the field as a computer support specialist. I became fascinated by this different type of operating system controlling one of the servers at a client’s place of business. Wanting to know more I decided to do some research as to what Unix was all about. It was during this time I was introduced to the world of free operating systems and free software.

I have spent a great deal of time researching all the information I could find on why someone would go to the trouble of creating an operating system that he would give away for free. It is through this research that I discovered a whole community of people dedicated to ensuring the Linux operating system would remain free as well as free software to go with it. These people remain, to this day, dedicated to improving Linux as well as creating software that meets or exceeds the needs of the those choosing to use the above.

Ubuntu is just one such version of Linux that is fast becoming the most user friendly operating systems. Ubuntu comes packaged with software most used by all of us. You will find applications such as Open Office, equivalent to the Windows version of Microsoft Office. You will find everything from games to Internet browsers, programming to sound and video and much much more. All of this free and supported. Have a problem with a certain software package? You will find the anwers available only a few keystrokes away. Type your problem in a browser and you will find a forum or website with the answer. If the answer isn’t there, just submit your request for help and someone will be eager to help you.

Since Ubuntu Linux is free and open source this means the program coding is also accessible. For those who are familiar with programming, this becomes a great advantage to changing the operating system or software as you see fit. Another advantage is that you can get involved by providing feedback as to your likes or dislikes. If you are a programmer you can tweek some of the software and submit it to be passed along to other like minded people wanting to see that Linux and the software packages remain free to use for everyone.

This article is meant as an introduction to the world of free operating systems and software. Stay tuned for more articles where I will be writing more in depth reports on the Linux operating system as well as the many available software packages that can be used with Linux.

File system is the most critical data structure of Linux operating system, which is responsible for organizing data on the hard drive. It ensures quick and easy accessing of your data from the disk. Linux uses file system entries to locate files on the hard drive and access them. But, in some cases, the Linux file system become read-only and you can not access data from your system. The system even refuse to boot up and you come across data loss scenarios. To retrieve lost data in such cases, Linux Data Recovery is required.

In a practical scenario, you may encounter the following error message on your Linux computer that is dual-boot with Windows operating system:

“Read-only file system”

The above error message occurs while mounting Linux partition. After this error message, you can not write or edit data on the hard drive. At the same time, your Linux system may stop responding and you need to do hard reboot.

This behavior of Linux operating system creates mayhem for you and your most valuable assets- data. It might create a thought in your mind that if you need to perform Linux Recovery or not. In order to find out the possibility of data recovery, you need to consider exact cause of this problem. The above issue may occur due to any of the below reasons-

Disk failure

File system corruption

Wrong unlock addresses for the LPC flash chip

If the hard drive is failed, file system is mounted in the read-only mode to prevent further damage to your system. To detect and fix the problem, try out following things-

Check file system errors. If you can not unmount the file system, force the file system check on next system boot. If you find any error, hard drive formatting and file system rebuilding is required.

Run fsck command-line utility on the failed Linux hard drive. It detects and repairs minor file system errors.

If you format the hard drive, all of your critical data is removed from the drive. In order to retrieve lost data in such cases, Linux Recovery solutions are required.

Recovery is best possible with the help of powerful and advanced Linux Data Recovery applications. The software work in all cases of logical data loss. With read-only conduct and rich graphical user interface, the applications are completely safe and easy to use.

Stellar Phoenix Linux Data Recovery is the most advanced and efficient tool for assured recovery. It recovers data from Ext4, Ext3, Ext2, FAT32, and FAT16 file system volumes. The software is compatible with all major distributions of Linux operating system including Red Hat, SUSE, Fedora, and Debian.

The operating system is a software whose function is to provide services to the user, whereby the operating system also serves as an interface between hardware and software. As we all know that, the computer consists of three basic parts, namely hardware, software and user.
The operating system acted as an intermediary between programs and hardware, imagine if in case there is no operating system, all programs are designed to be able to recognize all kinds of different hardware. This is where the operating system role, operating system provides services to programs about the details of hardware such as mice, keyboards, monitors, etc..

Brand operating system on the market very much at all, which distinguishes only be made by different companies and also they have different ways in terms of arrangement in the form of a memory access interface, how to use, etc. But it basically had the same role and functions. When you first run the computer, there is an initial program that must run, the program is called bootstrapping. This program manages all aspects of hardware, after the program is finished running, the next operating system will find stored in your hard disk, floppy, cd, etc.. Depending on which operating system is stored. After the operating system is found, then all the controls over hardware, be taken over by the operating system.

1. DOS (Disk Operating System) as its operating system
DOS is one of the operating system made by Microsoft, DOS itself provide services to users via a text based shell. Interface that is provided in the form of the command line, so users need to type the command with the keyboard to get a service
particular.

2 Linux as its operating system
Linux operating system is one that has the characteristics similar to UNIX operating system, Linux itself was created by Linux Torfald. Linux is open source which means all the source code can be changed and it has freely disseminated. Linux services provided is similar to DOS, but Linux can also provide services such as GUI (Graphical User Interface) based shell.

3. FreeBSD
FreeBSD is the only derivative of the UNIX operating system that is free. The operating system was mostly used as a server with a variety of purposes, because the famous toughness. To use this operating system, not too much different with the linux operating system.

The Unix operating system was conceived and implemented in 1969 at AT&T’s Bell Laboratories in the United States by Ken Thompson, Dennis Ritchie, Douglas McIlroy, and Joe Ossanna. Unix derived its name as a joke and reference to an experimental operating system that was slow and ineffective called MULTICS. It was first released in 1971 and was initially entirely written in assembly language, a common practice at the time. Later, in a key pioneering approach in 1973, Unix was re-written in the programming language C by Dennis Ritchie, (with exceptions to the kernel and I/O). The availability of an operating system written in a high-level language allowed easier portability to different computer platforms. With a legal glitch forcing AT&T to license the operating system’s source code, Unix quickly grew and became widely adopted by academic institutions and businesses.

Today Linux distributions are used in numerous domains, from embedded systems to supercomputers, and have secured a place in server installations with the popular LAMP application stack. Use of Linux distributions in home and enterprise desktops has been expanding. They have also gained popularity with various local and national governments. The federal government of Brazil is well known for its support for Linux. News of the Russian military creating their own Linux distribution has also surfaced, and has come to fruition as the G.H.ost Project. The Indian state of Kerala has gone to the extent of mandating for all state high schools to run Linux on their computers. China uses Linux exclusively as the operating system for its Loongson processor family to achieve technology independence. In Spain some regions have developed their own Linux distributions, which are widely used in education and official institutions, like gnuLinEx in Extremadura and Guadalinex in Andalusia. Portugal is also using its own Linux distribution Caixa Mágica, used in the Magalhães netbook and the e-escola government program. France and Germany have also taken steps towards the adoption of Linux.

Torvalds continues to direct the development of the kernel. Stallman heads the Free Software Foundation, which in turn supports the GNU components. Finally, individuals and corporations develop third-party non-GNU components. These third-party components comprise a vast body of work and may include both kernel modules and user applications and libraries. Linux vendors and communities combine and distribute the kernel, GNU components, and non-GNU components, with additional package management software in the form of Linux distributions.
