Data cleansing ought to be an essential process in any organization that keeps consumer data. It allows the highest data quality by de-duping, and suppressing and also appending key details which are personal too. The accuracy of a consumer data base will erode at a frightening rate. Data cleaning identifies movers, duplicating records and enhances personal details. In its simplest form, the software would be like a singular person or more than one person who reads the set of records to verify their accuracy.

The typing and spelling errors can be rectified while the data which is improperly filed, labeled, incomplete or even missing can be completed through this software package. Data cleansing can also be performed by computer programming. A more complex data cleansing program might also be able to fill in a missing city based on correct zip code or convert prices of items in the data base to Euros instead of US dollars. This software is ideally suited for developing an updated mailing list which can be sent to clients for promoting / selling various products. The process is very important for the efficient management of data dependent business.

In case the clients have not recorded the correct phone numbers or the client’s e-mail addresses have not been formatted accurately, the automated e-mail system is unable to send information on the latest special deals or coupons. The software based data cleansing ensures that all the data recorded within a system is up-to-date and accurate so that product details can be forwarded to the proper destination.

In areas where two data systems are working together, data cleansing is more effective. In case a manufacturing company has multiple branches, but may be dealing with the same customers, the data in each branch has to be complete, accurate and similar. When customers update their phone numbers within one branch, the data at the other branches need to have the same set of information ensuring that all the branches have identical data bank. In such cases the software based data cleansing also guarantee updated, accurate and consistent data between different records.

Often when storing a huge data base, errors are bound to creep into the system. The objective of data cleansing is to minimize or eliminate such errors and to make the data base appear as meaningful and useful as possible. In the business world the pivotal rule is that incorrect data base could be damaging and detrimental to the company’s commercial activities. Hence, data cleansing should be a mandatory operation of any business set-up to maximize profits and ensure their message gets out to the intended recipients.

Determined not to be defeated by flooding again, Carlisle residents took measures to protect their homes and businesses, so that when heavy rain had caused flood warnings to be issued in October 2008, they could be ready.

One such Carlisle-based business, Malcolm Dodds Solicitors, took out a hosting policy with DPS Software in order to protect their IT infrastructure in the face of such disasters.

Hosting is the process by which software that is traditionally run from a desktop PC is run over the internet in virtually the same fashion. All that is required is broadband internet access to the DPS data centre, other than that, users go about their work in exactly the same way. As IT infrastructure and maintenance is carried out off site, flooding and other such disasters do not effect IT systems and provided the building is accessible, hosting allows clients to carry on working as normal.

Hosting ensures that software is kept up to date while the host carries the burden of keeping hardware performance checked and maintained. In addition, the need for IT staff and expertise is removed to the hosting provider. This allows firms to capitalise on not only a wider variety of software, but also more advanced versions of hardware. This is beneficial for firms as they can use the same software as much larger competitors offering high levels of client service without the major upfront costs.

Malcom Dodds commented: “Hosting guarantees a trouble free software system. I no longer have any networking problems and I have not had to call on engineers since I went hosted. This has saved me a considerable amount of money, time, and lowered my blood pressure to acceptable levels!”

He added, “Updates were becoming a problem with crime as the LSC introduced contract changes on a regular basis and I was having to install all these on the computer on my network, but these are now dealt with by DPS.”

“I have always found the support staff at DPS to be excellent since I became a client over 14 years ago. It also makes the system more mobile and I can access my case management system from anywhere and particularly with the advent of digital dictation working away from the office becomes a viable alternative. It is all worth serious consideration.”

One such metadata structure is the superblock, which is very essential for the health of the Linux system. A file system cannot be mounted if you are not able to access the superblock. This case arises if the superblock is corrupted that can happen because of various reasons such as virus infections, power outages, file system corruption, human errors, etc. In such cases, you should take appropriate corrective measures to recover the file system. If you are not able to resolve the issue, then you should use a third-party Linux data recovery software to perform data recovery of Linux system.

Consider a scenario wherein you have an ext3-partitioned Linux system. When you try to access the  partition, you are not able to do so. An error message is displayed, that is:

“/dev/sda2: Input/output error

mount: /dev/sda2: can’t read superblock”

Cause:

The cause of this error message is that the superblock has corrupted because of the aforementioned reasons.

Resolution:

You can restore the primary superblock from the various backup copies that the Linux system maintains for such situations. To do this, you need to perform the following steps:

Find out superblock location for /dev/sda2

Check and repair the Linux file system using alternate superblock # xyz, where xyz is the location of the alternate superblock.

Mount file system using mount command viz, # mount /dev/sda2 /mnt

Try to browse and access the file system.

However, if you still are unable to address the situation, then you should use a third-party Linux data recovery software to perform Linux recovery. Such tools are read-only in nature and perform Ext3 Recovery without overwriting the original data.

Stellar Phoenix Linux Data Recovery software is a Data Recovery for Linux software that enables you to perform Linux data recovery for various file system volumes. Apart from ext3 recovery, it is capable of performing ext2 recovery and ext4 recovery. In addition, this Linux recovery tool recovers data from various types of hard drives such as SCSI, SATA, EIDE, and IDE. It supports different Linux distributions such as Red Hat, SUSE, Debian, Caldera, Mandrake, Sorcerer, TurboLinux, Slackware, Gentoo, etc. It is compatible with Windows 7, Vista, Server 2003, XP, and Server 2000.

A dual boot or multi boot is a system in which two operating systems are installed on a single hard drive, letting you boot from either of the operating system. The boot loader is a program which allows you to have dual booting.

General combination of operating systems exercised in dual booting includes Linux and Windows. The dual booting allows you to use features and functions of both of the operating systems on a single computer. Dual boot systems are mostly useful for programmers and testers.

Although, dual boot systems are very useful but sometimes they can also cause several problems. A minor mistake made by the user while making a dual boot system can lead to the several catastrophic problems.

A common mistake made by the users, while making a dual boot system, is selecting “prepare hard drive” option. This option appears you when you install Windows operating system on a Linux system, in order to make it multi boot.

When you use this option, all of the hard drive partitions and stored data gets deleted. After that new partitions are created and the operating system is installed. When the installation will complete, you will have a blank hard drive without any operating system and data. Everything, which was previously stored on the hard drive, will be deleted.

Data loss and hard drive partition loss is the worst case scenario which a computer user, either general or professional, could face. It can cause several nightmares and can possibly put you out of the business.

In such circumstances, it becomes really important to recover your precious data from the formatted hard drive to save you and your business. The data recovery in these cases needs to be performed for the Linux data.

The data recovery Linux is possible through the use of Linux data recovery software. Linux recovery software is the applications, offered by the several data recovery companies, to handle all the data loss situations.

A powerful data recovery Linux software does a thorough scan of the hard drive and extracts data up to the maximum level of possibility. To ensure the absolute Linux data recovery, selecting powerful Linux recovery software of trusted brand is worth.

Stellar Phoenix Linux Data Recovery software is the most influential hard drive recovery software provided by the most trusted name of the data recovery industry- Stellar. This software is able to attend all the data loss scenarios and recover data in a quick and easy way.

This Linux Recovery software is extremely powerful and easy to use so that you can carry out Linux data recovery without having any sound technical knowledge. This software supports all the Linux file systems such as Ext2, Ext3 and ReiserFS.

If you are a Linux user, then you must have used a utility, known as Boot Loader. It provides different levers of functionality and support, through its different variations. Along with the boot operations, Linux boot loader also handles errors and helps you keep your system functional. Boot loader generally handles boot and memory errors at start up. However, in some cases, the boot loader can not fix the errors, which makes your system unbootable and unusable. In such circumstances, you can not access the data stored on your Linux hard drive and eventually face data loss. In order to extract lost data from the Linux hard drive in such situations, you need to opt for linux data recovery solutions.

Two most popular boot loaders of Linux operating system are:

LILO (Linux Loader)- It comes as default boot loader of all Linux distributions. As one among the oldest boot loaders, its strong Linux community accompaniment has enabled LILO to develop over time and remain useful as an operational modern boot loader. Some novel functionalities, such as exploitation of newer BIOS (Basic Input/Output System) functions and improved user interface, make this boot loader more stable and reliable.

GNU GRUB (Grand Unified Boot Loader)- It is considered as a replacement of LILO. It is based on original GRUB program and developed by Free Software Foundation. GRUB is reference implementation of Multi boot Specification that enables you to have various operating systems on same computer and select which one to use for booting.

Both these boot loaders allow Error Handling for proper functioning of your Linux computer.

Error Handling:

It denotes anticipation, detection, and finally, resolution of the operating system or application errors. The Linux boot loaders forestall most of such errors, recover your system from them when the errors occur, without affecting the system operations.

Although, boot loader error handling is a useful process, but if the critical errors can not be handled by Linux boot loaders, your system may become unstable. Such situations may cause data loss and require data recovery linux to be fixed.

Linux Data Recovery is possible using powerful and advanced linux recovery software. They are particularly designed to thoroughly scan whole Linux hard drive and extract all lost, missing, and inaccessible data. The applications are capable of handling virtually every type of logical data loss situations and enabling safe and easy recovery.

Stellar Phoenix Linux Data Recovery software recovers lost, missing, and inaccessible data quickly and successfully. It supports all major distributions of Linux operating system, such as Red Hat, SUSE, Ubuntu, Fedora, Mandriva, and Debian. The software recovers lost Linux data from Ext4, Ext3, Ext2, FAT32, FAT16, and FAT12 file system volumes.

To work around this issue, you need to install the latest version of Linux kernel. It may include ‘forcedeth’ patch, which is capable of resolving most of the incompatibility issues.

In some cases, after installing the latest version of Kernel, when you reboot the Linux system, you might face the following error message:

“fsck.ext2: No such file or directory while trying to open /dev/hda8. The super block 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 super block is corrupt, and you might try running e2fsck with an alternate super block: e2fsck -b 8193 <device> fsck failed.”

After this error message, neither the system boots nor any file can be accessed.

Grounds of the issue

As stated in the error message, this problem generally occurs due to super block corruption or file system corruption.

è Super block and file system are two most important data structure of Linux system. Proper functioning of both these is required for ensuring effective working of the system.

After corruption, the operating system could not locate the file and thus can not retrieve it.

Resolution

To work around this problem, you need to install a fresh copy of super block and file system. It is possible through formatting of the hard drive and reinstallation of operating system.

Though, it will remove the errors but will also erase all the data stored on your hard drive. It is the worst scenario of data loss and needs Linux data recovery to get it fixed.

Linux data recovery is feasible with the application of third party Linux recovery software known as Linux data recovery software. Linux recovery software is easy to use and thus allow you to have simple and fast data recovery Linux.

Stellar Phoenix Linux Data Recovery is the most advanced Linux recovery software offered by the data recovery giant- Stellar. This data recovery Linux software works well in all data loss cases and allows Linux data recovery for all sorts of files.

Stellar Phoenix Linux Data Recovery software is powerful enough to carry out efficient scanning of entire hard drive and extract all lost data from it. The user interface of this software is very interactive and thus does not require any sound technical knowledge from users’ side.

At this point, it becomes essential to opt for Linux data recovery to retrieve lost, missing or inaccessible data from your Linux hard drive. In a practical scenario, when you try to boot your Linux computer that is using Ext2 file system, you might come across below error message: “EXT2-fs error (device 09:00): ext2_check_descriptors:

Block bitmap form not in group (block 3670099)! EXT2-fs: group descriptors corrupted” In Ext2 file system, Block Groups are the critical components that commutatively create file system and design block group descriptor that is responsible for controlling and managing file creation and accessing tasks. This significant data structure possesses Super Block, Block Bitmap, Inode Table and Inode Bitmap like information that plays a very critical role for Linux data accessing. In case of corruption to these data structures, you need data recovery linux to salvage data from your Linux hard drive.

Root of the problem

This behavior of Linux operating system occurs due to corruption to the block bitmap. Block bitmap works as a map of all the blocks in group. If you run fsck in this situation, you encounter corruption error message, which states that your file system is harshly damaged. If you manage to locate the damaged data structure and can replace it with alternative one, you can make your system functional. But this method does not help you to recover your data. To retrieve valuable data from hard drive, Linux Recovery is required. Recovery is best possible using third party Linux data recovery software. The applications are capable of methodically scanning affected Linux hard drive and extract all of the lost data from it. These tools are completely easy to use as they have interactive and simple graphical user interface. With non-destructive conduct, the applications never alter original data on the hard drive.

Stellar Phoenix Linux Data Recovery is the best ever made and the most effective application for absolute recovery. It work well with all major distributions of Linux operating system. The application recovers all lost, missing or inaccessible data from Ext4, Ext3, Ext2 and ReiserFS file system volumes.

Superblock is the most significant component of a Linux volume that restrains critical information about files and folders in file systems as ext2, ext3 and more. It enables us to mount and access the file systems. Superblock corruption primarily occurs due to metadata structure damage, file system corruption, unexpected system shutdown, malicious software like virus and more.

In most cases of superblock corruption, the volume becomes unmountable and the data becomes inaccessible. In such situations, you can restore the lost data using an updated backup. However, if you have not maintained any backup or it is not up-to-date, then you need to recover your data by using advanced Linux Data Recovery tools.

Consider a practical scenario, when you attempt to boot your Linux system, you encounter the below error message:

“Wrong fs type, bad option, bad superblock on /dev/hda8, missing codepage or helper program, or other error. In some cases useful info is found in syslog – try dmesg | tail or so”

After running dmesg tail, you encounter the below error message:

“Couldn’t mount because of unsupported optional features (2000200)”

After the above error message appears, the system becomes unmountable and data stored on the hard drive volume becomes inaccessible. Additionally, you encounter the same error message each time you attempt to boot your system.

Cause:

The main reason behind occurrence of the above error message is superblock corruption.

Resolution:

To resolve the problem and access all inaccessible data, you need to follow these steps:

1. Boot your system by using an alternate block by running the below command:

e2fsck -b 98304 /dev/hdb8

2. Once the file system gets restored to the point at which it can be mounted, you need to fix it by using this command:

e2fsck -c /dev/hda8

-c parameter checks for the bad blocks

However, if the above steps are not able to resolve the issue, you should consider reinstalling Linux. A clean Linux reinstall will erase all existing data from the selected volume. For complete recovery of lost data, you should use efficient Linux Data Recovery software.

Such Linux Recovery tools incorporate effective scanning algorithms to recover all your lost data. These recovery tools provide highly graphical user interface that makes them easily understandable without prior technical knowledge. These tools recover data post situations like superblock corruption, group descriptor faults, inode table damage and more.

Stellar Phoenix Linux Data Recovery is the foremost Linux Recovery tool. It supports recovery from Ext2, Ext3 and ReiserFS file system based Linux volumes. This Data Recovery Linux tool gets installed on Windows (Vista, XP, 2003 and 2000) and the affected Linux drive is connected as slave.
