Losing data from hard drive in such situations creates big problems for your business. So, you need to restore data from the latest backup to prevent data loss. However, in case backup is not updated or available, Linux Recovery solutions come to your help.

When you face boot errors, your Linux system refuses to boot properly. There are various types of boot errors, depending upon the type and cause of failure. One such error is SCSI CRC error. You may come across the below error message when your Linux operating system loads:

“Creating Root Device

mounting root filesystem

(scsi:0:0:0:0) CRC error during data-in phase

(scsi:0:0:0:0) CRC error in intermediate CRC packet

scsi: aborting command due to timeout: pid 0, scsi 0, channel 0, id 0, lun 0 read (10) ……”

The above error halts Linux boot process, making your hard drive inaccessible. To retrieve lost data in such cases, identify the problem and perform Data Recovery Linux by resolving it.

Cause

On the first appearance, this issue seems to be associated with hardware problems, but this is not the case. You may face this behavior due to any of the below reasons:

• Damaged or missing /boot directory from Linux operating system installation.

• File system error or corruption.

• Missing or corrupted initrd.

/boot directory is a major component of Linux operating system, which contains critical information about booting parameters and process. While initrd is a temporary data structure, which makes preparations before mounting of root file system.

Resolution

Use Rescue CD of Linux operating system to overcome this problem by restoring damaged /boot directory and initrd. When it fails, go for Linux Data Recovery software to retrieve lost data.

The Linux Data Recovery applications are able to scan damaged Linux hard drive and extract all lost data from it. They have read-only conduct on the drive to ensure safe recovery, without modifying original data on the disk.

Stellar Phoenix Linux Data Recovery is the most comprehensive and advanced utility to ensures absolute recovery of lost data. The software works well with all major distributions of Linux operating systems, such as SUSE, Debian, Red Hat, Ubuntu, and Fedora. It recovers data from Ext4, Ext3, Ext2, FAT32, FAT16, and FAT12 file system volumes.

Are you unable to boot your Windows 7 or Windows Vista operating system-based computer, after making it dual-boot with an earlier version of Windows operating system? Do you encounter error when your system tries to read disk? This behavior of Windows may occur due to various compatibility issues and make your system unusable. At this point, you can not access your hard drive partitions and encounter partition loss situations. In order to recover lost partitions in such circumstances, Windows Data Recovery is required.

As a practical example, you may come below issues after installing an earlier version of MS Windows on a Windows Vista or Windows 7-based machine in dual-boot configuration:

Windows Vista does not boot after making your system dual-boot. Only earlier version of Windows boots up.

When you install an extra instance of Windows XP on a system, which has Windows Vista and Windows XP in dual-boot configuration, the below error message occurs.
“Disk read error has occurred.”

This behavior make your system inaccessible. To recover lost partitions in such cases, it becomes essential to find the cause of this problem and perform Windows Data Recovery by sorting it out.

Reason

This behavior of Windows operating system occurs as earlier versions of MS Windows are not compatible with Windows Vista boot method. Vista employs a new BCD (Boot Configuration Database) store. The BCD includes a boot menu and the information about the operating system, which are installed on your computer. Thus, the Boot.ini file which is from earlier version of Windows can not be used for booting up Windows Vista.

Resolution

You can try out the following things to work around this problem:

Use the Bootsect.exe for restoring Windows Vista Master Boot Record (MBR) and boot code, which transfers control to Windows Boot Manager (WBM) program.

Use Bcdedit.exe for creating a manual entry in BCD Boot.ini file in earlier version of Windows.

Reboot your system.

If the above method does not work, you need to format your hard drive and reinstall Windows Vista. In this case, you will lose all your hard drive partitions and need to Recover Partitions.

The make it quite easy to retrieve lost hard drive partitions. The software are able to handle all types of partition loss situations, using advanced scanning methods.

Stellar Phoenix Windows Data Recovery is the best made software that provides assured recovery of lost Windows partitions. It recovers FAT16, FAT32, VFAT, NTFS, and NTFS5 file system partitions. The software is designed for Microsoft Windows 7, Vista, 2003, XP, and 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.

Partition Boot Sector is one of the most significant data structures of a Windows hard drive partitions. It is a small area of hard drive partition, which stores critical information about the file system of your Windows operating system (either FAT or NTFS) and a small machine language program. The machine language program is required to assist the operating system when it loads. Operating system can not recognize the partition if partition boot sector is faulty.

In some cases, the partition boot sector may get damaged and it renders the hard drive partition inaccessible. The corruption may occur due to virus infection, improper system shutdown, operating system malfunction, and power surges. Nevertheless of the cause of this problem, it eventually leads to partition loss and require Windows Partition Recovery to be handled.

Resolution

When you suspect that Microsoft Windows does not boot up because the hard drive partition boot sector is damaged, use special Recovery Console option in Windows. This special recovery console utility is known as Fixboot to sort out all types of boot issues.

You can access this tool by booting your system through Windows boot disk. Enter the Recovery Console and type:

“Fixboot [drive]:”

The [drive] is letter of hard drive for which you need to repair the partition boot sector.

If the above method does not work, you need to use Partition Recovery Software that work in most of the partition loss situations. The applications methodically scan whole hard drive using efficient scanning techniques and ensure absolute Partition Recovery. The tools come equipped with interactive and self-descriptive graphical user interface and thus do not demand sound technical skills. They do not alter original data on the drive as they have read-only and non-destructive conduct.

Stellar Phoenix Windows Data Recovery is the most effective solution for all types of partition loss problems. The software is designed for Microsoft Windows 7, Vista, 2003, XP, and 2000. It recovers FAT16, FAT32, VFAT, NTFS, and NTFS5 file system partitions and stored data.

When you try to boot your Linux computer, you may receive the following warning message:

“EXT2-fs warning: mounting unchecked fs, running e2fsck is recommended”

After the above error, when you run ‘e2fsck’ utility, you face further error messages that resemble the followings:

•    TivoMaster:/var/tmp$ e2fsck -y /dev/hda7 e2fsck 1.06, 7-Oct-96 for EXT2 FS 0.5b, 95/08/09 e2fsck: Bad magic number in super-block while trying to open /dev/hda7

•    The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock:

e2fsck -b 8193 <device>

This behavior of Linux operating system renders all your data inaccessible. In order to access your valuable data, you need to identify the cause of this problem and perform Data Recovery Linux by resolving the problem.

Root of the problem

This problem may occur after improper system shutdown without unmounting the root file system. After this, the root file system may get damaged and you will face the above stated problem.

Resolution

You can sort out this problem by formatting the hard drive and reinstalling Linux operating system. After formatting, you need to restore data from the current backup as it removes all the data from hard drive. However, if the backup is not available, Linux Recovery becomes essential.

Recovery is possible using advanced tools, known as Linux Data Recovery software. These software are designed to scan damaged hard drive using powerful algorithms and extract data that can not be accessed normally. They perform absolute recovery in a safe and easy way.

Stellar Phoenix Linux Data Recovery is the most effective tool that insures perfect recovery in all cases of data loss. The software is developed to recover data from Ext4, Ext2, Ext2, FAT32, FAT16, and FAT12 file system volumes. It works well with all major distributions of Linux operating system, include Debian, Mandriva, SUSE, Red Hat, Fedora, and Ubuntu.

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.
