Is your Linux hard drive crashing abruptly every time when you boot your system? Are you unable to boot your Linux computer and access data from it? Well, the problem may occur due to numerous reasons, which cause hard drive crash. Most commonly, this problem occurs due missing or corrupt data structures of your Linux hard drive. Due to the same, operating system can not locate stored files on the hard drive and access them. At this point, you need to opt for Linux data recovery solutions to get your valuable data recovered.

Crash of a Linux hard drive is indicated by various symptoms. Such symptoms include the following ones:

Your Linux operating system-based computer does not boot up.

You encounter various error messages, such as “No Fixed Disk Present” or “DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER”

Black or blank screen after you power up your system.

System reboots, freezes, or stops responding frequently.

“Operating system not found” and “Drive not formatted” messages.

Hard drive crash can be caused by various reasons and renders entire system inaccessible. The most common reasons of Linux hard drive crash are as given below:

Boot sector virus or damaged MBR (Master Boot Record).

Corrupted or damaged file system of Linux hard drive.

Missing or damaged system files or operating system.

Virus infection.

Corrupt Superblock or other critical meta data structures.

When system crash occurs, it becomes impossible for the operating system to locate files on hard drive. If it can not locate and access the files, which are required by Linux operating system to boot up, the boot process fails.

In order to fix a crashed Linux hard drive and perform Data Recovery Linux, you are required to format it and reinstall operating system. This process replaces all the missing, corrupt, or damaged system resources and bring the hard drive back to life. However, it also removes all the data from hard drive and create needs of Linux recovery.

Recovery is best possible using advanced and efficient commercial software, known as linux recovery software. They use high-end scanning techniques to carry out in-depth scan of entire Linux hard drive to extract all lost data from it.

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.

Data loss is a terrible situation, which may occur to any system, irrespective of the operating system and hardware platform. Sometimes, you may find that your Linux computer does not boot properly or you can not find stored data on your Linux hard drive. This behavior leads to data loss. Data loss occurs due to numerous reasons, related to system errors and user errors.

In such situations, a complete backup of your significant data proves to be of great help. However, if the backup is either not available or not updated, you have to opt for Linux Data Recovery solutions to get your precious data recovered.

Your precious data from Linux hard drive may get lost because of a number of reasons, which include:

• Accidental deletion of important data files or unintentional hard drive formatting.

• Virus has infected your system and damaged its significant data structures.

In Linux operating system, fsck (file system check) is a command-line utility that allows you to check file system and hard drive integrity. Using this tool, you can even fix some minor errors of file system. Generally, it runs automatically during system boot when Linux detects that the file system is not in consistent state, indicating improper system shutdown like power loss or system crash. However, if you run fsck tool on physical volume, you may come across some odd error messages. The errors prevent you from accessing your data and lead to data loss. At this point, you need to use Linux Data Recovery solutions to extract lost data.

When you get such error messages, experts suggest to use the ‘pacman’ utility for upgrading your Linux kernel and reboot the system for finalizing this operation.

Pacman is an application of  Linux operating system, which is used for managing other applications. This tool uses simple files in form of packages and organizes the text-based databases. This is helpful in adding, deleting, and upgrading the packages in Linux computer.

After completion of kernel up-gradation process, if you try to restart the system, system does not boot up. It may stuck on the boot screen. Despite of loading the GRUB (Grand Unified Boot Loader) and starting, the system just display “loading GRUB” message.

In such cases, if you boot the system using floppy, you may get the below error message:

“ERROR: (device hda1): XT_GETPAGE: xtree page corrupt
ERROR: (device hda1): XT_GETPAGE: xtree page corrupt”

Subsequent to above error message, if you run fsck tool, the following error occurs:

“Errors detected in Primary File/Directory Allocation Table.
File system object FF65726 linked as: /var/run/random-seed
File claims cross linked block(s).
Cannot repair FF65726.”

Cause

This problem is caused by corruption to GRUB or Linux file system. In such cases, hard drive formatting is required, which removes all the data from hard drive. To recover lost data, Data Recovery Linux is required.

You can recover lost data using Data Recovery Linux applications. These are third-party applications, which are capable of methodically scanning the entire storage media and extract lost data from it. The Linux Recovery Software have simple and self-descriptive rich graphical user interface to provide ease of use. With read-only and non-destructive conduct, the applications are safe to use.

Stellar Phoenix Linux data Recovery is the best ever made tool for quick and safe recovery of lost Linux data. It recovers data from Ext4, Ext3, Ext2, FAT32, and FAT16 file system volumes. The software works well with all major distributions of Linux operating system.

In Linux operating system, fsck is a useful utility that helps you to check file system integrity and fix the errors. It is helpful particularly in case of file system corruption, dirty system shutdown and operating system related issues. When improper system shutdown happens, fsck runs when you reboot the system and check file system integrity. But if fsck process gets terminated due to improper system shutdown or power failure, you might come across serious data loss issues. In such circumstances, you are required to opt for effective and powerful Linux Data Recovery solutions.

In a practical scenario where fsck process gets interrupted due to power outage, when you restart the system, all of your hard drive volumes are found to be inaccessible. It cause critical data loss situations. When you try to sort out the problem by using fdisk command on Linux hard drive, you see following message: “Warning: invalid flag 0×0000 of partition table 4 will be corrected by w(rite) Command (m for help): p Disk /dev/hdb: 203.9 GB, 203928109056 bytes 255 heads, 63 sectors/track, 24792 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System Command (m for help):”

Cause

As stated in the above error message, the problem is caused by corruption to partition table. It is an important data structure of Linux operating system that stores important information about hard drive partitions/volumes. It is a 64-byte table, which store four partition entries, 16 byte for each. Damage to the partition table means your operating system could not locate partitions on hard drive and thus can not access them. In other means, you need to carry out Data Recovery Linux for fixing this issue.

Resolution

In order to work around this issue, you need to format the hard drive and reinstall Linux operating system. It will replace the damaged partition table with new one, after that system will work perfectly. But formatting the drive would remove all the data from it and you face serious data loss situations. Linux Recovery in such situations is possible using commercial Linux Data Recovery software. The applications are completely safe and easy to use and perform absolute recovery in most of the data loss situations. Stellar Phoenix Linux Data Recovery is the most comprehensive solution for all types of data loss situations. It recovers lost data from Ext4, Ext3, Ext2 and ReiserFS file system volumes. The application is usable with all major distributions of Linux operating system.

Mac OS is the most efficient and competent OS now a days. This operating system has several added features along with the features of the earlier operating systems of this series. Although Leopard is more powerful and full features operating system from Apple, but it has a huge bug. In this operating system when you move a file from one volume to or from another volume.

Once you try to move operating for a particular file or folder and while you choose to cancel the operation, it deletes the original file without making any copy of the file. When you move a file to or from different volumes, a new reference of that file in created on the file system of other volume and data is read from the source of the original file, and written to the specified destination.

If you will see that the moving operation completes successfully, the original file is deleted and when you cancel it, it should display a message “Moving Failed” without deleting the original file but leopard deletes the file in both cases. This problem occurs because the finder of the operating system fails to ensure that the file has been written successfully to the destination before deleting the original file.

This bug can lead to the big problem of data loss in Mac operating system. In these situations, you can’t find the data on both original and target location and you can lose them. In these conditions of data loss, you need for data recovery solutions to recover these lost data from Mac operating system. You can use data recovery software known as Mac Data Recovery to recovery your lost data.

Macintosh data recovery software are specially designed data recovery software tools that can help you in recovering your data in all possible cases of data loss. These Mac Recovery software use advanced searching algorithms to search and locate the lost data from Mac volumes and restore them in their original format on their original location.
