How to resolve hardware Error in Linux Operating System

The booting process of the Linux OS can stop due to many software reasons like file system damage, metadata structure corruption, virus infection, improper system shutdown etc. and hardware bad connection, inappropriate electrical connections etc. issues. In such non-booting situations the data saved in the hard drive becomes inaccessible.

For complete access of your data, you require to restore it from the latest backup. But in case of no backup availability you should use effective Linux recovery software for software corruption issues. However, if the corruption of data has been caused due to some hardware issues and there is no backup available, Linux data recovery services come to help.

Consider a practical scenario, where you get error message when you attempt to boot the Linux OS.

“The System Log Says, end_request: I/O error ...”

When above error message appears the system becomes unbootable and the data saved in hard drive becomes inaccessible. In addition, you encounter the same error message each time you try to boot your system.

The main reason for the occurrence of the above error message is the hard drive error. Some causes that could result in hard drive error are discussed below:

• Bad connection to the hard drive, especially with home brew systems

• Interruption of the electric signals between the system board and the chassis

To avert the occurrence of the above error message, you need to follow these measures:

• Always use new ribbon cables

• Make sure that the electrical connections are tight and clean

To resolve the above problem and access the data, you need the help of Linux Recovery Services. These services are primarily performed by highly knowledgeable data recovery experts. These experts are fully capable of recovering and restoring the lost data in all possible cases of physical data loss. Furthermore, for absolute and systematic recovery of data from a physically damaged hard drive, the data recovery technicians need to perform recovery in Clean Rooms facility. To select the data recovery company , you need to firstly view the track record of that organization.

How to Recover Linux Error ´Currently has loop partition layout´

Linux-based hard drive is basically divided into two major types of partitions: data partition and swap partition. Data partitions are the basic partitions that contain system data, including that for starting and running the system in root partition. On the other hand, swap partition is responsible for holding hard disk extra memory and expanded system´s physical memory. In many of the Linux systems, fdisk is used to initially set the partition type. These partitions can be ext3 journaled, ext2, ext4. But, sometimes you may observe certain issues with these partitions. Thus Linux data recovery experts suggest maintaining an updated backup of important data that is stored on hard disk.

Consider a situation, you try to mount a Linux partition to install a Linux distribution and face a similar error message:

"/dev/hdg currently has loop partition layout."

Where, name of partition, i.e. /dev/hdg, can vary. It can be /dev/had, /dev/sda tc.

Possible reasons of above error message are listed below:

If you are using a third-party boot loader on primary hard disk´s MBR, Disk Druid may fail to recognize your partitions.

Partition layout is damaged

Disk Druid is the tool to manage partitions and associate mount points. It is a graphical tool that displays existing disks and partitions in a defined format.

You can follow these steps to recover from the situation:

If boot loader has been the issue, uninstall the current boot loader and install GRUB on MBR of primary hard disk.

If partition table is damaged, backup all exiting and information files and folders and repartition the drive. Restore lost data using backup. If backup has not been taken, is damaged or incomplete, you can use commercial tools of Linux Recovery.

Linux recovery software are advanced recovery applications that can scan drive affected from logical data loss. These applications use some algorithms that completely analyze existing disk structure. After locating missing files and folders, they compare their location information with that of existing ones. All the procedures are safe. Also, the interface provided is interactive and offer easy Linux Recovery options.

‘Group descriptors corrupted’ Linux Error

Ext2 and ext3 file systems space is divided into blocks, which are further organized into what we call as block groups. For each group block, there is a data structure that defines it and contains valuable information, called group block descriptor. This data structure helps accessing block groups and includes inode bitmap, inode table and blocks bitmap location information. Group descriptors take consecutive places and collectively form group descriptor table.

In case of group descriptors corruption, whole file system is taken as damaged. Corruption usually results due to unexpected system shutdown and virus attack like cases. While they are corrupt, system may not boot at all or show errors similar to:

“EXT3-fs error: ext3_check_descriptors / group descriptors corrupted”

For each block group, table of group descriptors is placed after the copy of superblock. To avoid Linux data recovery needs while file system corruption, group descriptors for each block group are duplicated. While normal run, system uses only first copy of group descriptors.

We can use fsck and attempt repairing file system corruption in such cases. But in case of extensive damage, fsck rarely can remove all errors. Thus, we need to recreate whole file system by formatting the drive. But prior doing this, we need to backup all the required data.

Backup must be complete. So after carrying out backup, we need to check for its status. Also, it is recommended to check if backup contains all required files. However if backup is found to be incomplete or unproductive, we can use Linux recovery applications to extract lost data.
Linux Data Recovery Software can be used for affected media itself that scan and recover lost data. These applications carry out data recovery Linux using powerful scanning algorithms. Also, they are easy to use due to interactive interface.

Resolve Unexpected Inconsistency Error in Linux

Linux is considered to be a reliable operating system due to the data security features it offers. But due to reasons like unexpected shutdown, a Linux filesystem might get corrupt and prevent you from accessing the data. When you turn on a Linux system, fsck runs if finds any errors on the disk. However, if boot-time fsck cannot perform the desired repair task, it returns errors. To resolve such problems, you might need to reinstall the OS. You should use your backup to restore the lost data or scan the hard disk using Linux data recovery software.

For an instance, when you try to boot a Linux based system, it fails and gives the similar error:
"/dev/sda5: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY
(i.e., without -a or -p options)"
You cannot access the data stored on your hard disk after this error message occurs.

Cause

Boot time 'Unexpected Inconsistency' generally occurs due to filesystem defects. Your filesystem might be corrupted. Main causes for such defects are:
Improper system shutdown. For performance reasons, a Linux system performs filesystem buffering in its memory. The data written to the buffer memory is updated on the hard drive usually in every 30 seconds. The Linux filesystem might get damaged if an unexpected shutdown takes place while the write process is still running.
·Faulty hardware: A damaged hard disk controller or disk itself can eventually corrupt a file system.

Solution

Below are the steps that you need to undertake to solve the existing issue:
·Use Linux Rescue CD or installation disk to boot the system
·Execute the following command while making sure that the affected disk is not mounted:

e2fsck -f -c -y /dev/sda5

Ø-f option checks the filesystem even if it is appearing consistent
Ø-c options check the disk for bad sectors
Ø-y option answers 'yes' to all the questions while making repair

·If e2fsck fails, you need to format the corrupted disk and reinstall Linux. Restore lost data from backup thereafter.

While the unavailability of valid backup, you need to use Linux Recovery applications to search and restore the lost data. Linux Data Recovery tools employ high-end scanning algorithms and are competent to recover data in all set of conditions of logical crash.

Resolve Error Message in Linux OS "Must load Linux kernel before initrd"

Boot loaders such as GRUB (Grand Unified Bootloader), LILO (Linux Loader) etc. enable you to select to boot a particular OS in multiboot or dual boot systems. After selecting the OS (for example Linux), the booting process initially starts with the booting of Linux Kernel program. A Linux Kernel program is the central component of a computer OS. It requires the corresponding drivers to access the device on which the file system is based. To remove any conflict due to all imaginable drivers in the kernel, it uses initial ramdisk (intrd). The intrd is the temporary file system, which is mostly used for preparations before the real root file system can be mounted. Problems might occur when intrd gets loaded before Linux Kernel program. In such conditions, the hard drive volume becomes un-mountable and the data saved in the hard drive becomes inaccessible. You need to recover your data from the latest backup. In case, no backup is available or the backup is corrupted, you need to use efficient Linux data recovery applications to recover your lost data files. Consider a practical example, when you attempt to boot Linux operating system, you encounter the below error message: "Must load Linux kernel before initrd" The above error message occurs each time you try to boot the Linux operating system on your computer. After the above error message appears, the data saved in the Linux volume becomes inaccessible.

The above error message mainly occurs when the intrd gets loaded before the Linux Kernel program.

To resolve the above error and access the data, you need to remove the intrd from your computer. However, if you still encounter an error, then only option left is to access the volume by reinstalling the Linux operating system. A clean reinstall of the operating system will erase all previously stored data in the hard drive. In such scenarios, you need to recover lost data by using effective Linux data recovery software. These advanced recovery applications incorporate high-end scanning methods to recover lost data from a logically corrupted hard drive.

Error in Linux ‘The System Log Says, end_request: I/O error ...’

The indicatives of the hard drive failure or defect are few and different for varying OS. Regardless the number, the impact which they draw on the data is dangerous, the hard drive defect in any case lead to the data loss and hence the need of data recovery. For example, the following error message which occurs in the Linux operating system:

‘The System Log Says, end_request: I/O error ...’

This error message is the strong sign of the hard drive error or defect. Either of the physical assembly of the hard drive parts has got messed up leading to the critical situation of the data loss and thus you have to look for the better tools aimed for Linux data recovery.

The one and the only way to avoid the situation is to shut down the system immediately and call for the Linux recovery services. If you are sure that whatever data was there on the failed hard drive is back up, then restore it to a non-defected hard drive. This is best way to avoid spending money on the data recovery Linux services.

Before giving all the blames to the hard drive, make sure that all the connections to the drive are in good condition, especially with the home prepared systems, as this error message may also generate with this regard.

If the connections between the system board and the chassis are going on the bad grounds then this is the another reason for the same error message. So be sure that all the electrical connections are in proper condition.

If you decide upon the hard drive defect then better consult the Linux data recovery service at your place. Basically the data recovery services for all the OS have common causes. Data recovery linux be carried out by the geek data recovery experts who will analyze your hard drive and will work accordingly to end up the best for you.

Data is the most relevant governing factor for the organization and so risking it by choosing the incorrect Linux recovery services is not accepted. Look into the track record of the company and opt wisely.

How to Recover Data Lost while Resizing Ext2 Partition in Linux

Different Operating Systems use different file systems to manage their files stored on hard drive. File System is a method for storing and organizing computer files and the data they contain to make it easy to find and access them. Like FAT and NTFS file systems in Windows, Ext2 or Extended File System is a file system used in Linux Kernel. It is faster file system and it is used as the benchmarking standard.

We use file systems on the logical partitions of hard drive. Hard drives are partitioned to store one kind of data on one partition to manage them effectively. Different partitions can have different size.

Sometimes we need to resize the partitions. It is generally required in two cases:

1. When the particular partition is small and the amount of data is big.
2. When the partition is big and it decrease the accessing speed.

If any of these conditions take place, we resize the partition by increasing or decreasing the size of other partitions. We can resize the partition using two methods:

1. Formatting and deleting the partitions and them repartitioning the drive.
2. Resizing dynamically using software

In case of formatting the drive, data loss may occur. To save the data, we need to resize the partitions using software. These software resize the logical partitions without formatting the drive or affecting the existing data. With the help of these software, you can resize the partitions very easily.

Along with the advanced feature of these software have some drawbacks. They can cause data loss in some instances. For example if your want to increase the size of Logical Drive “D” by taking 5GB space from Logical Drive “E”. In case if you don’t have 5GB of free space on E drive the software will delete the existing data on the drive and take the space for D. in this way, the software may cause data loss.

In these circumstances, the data from drive E become inaccessible and you need for data recovery to recover the lost data. You can perform this task using Linux recovery software.

Linux data recovery software are the application programs designed to recover data from Linux Operating System. In this particular case, you need to purchase a data recovery software that can recover data from Ext2 File System. Before purchasing any Data Recovery software, you should make sure that the particular Linux data recovery software you are going to purchase will support the recovery from Ext2 file system or not.

Data recovery in Linux and library file errors

When you start any application on your Linux system, you may come across with the following error message:

“Program name: error in loading shared libraries: lib ***…so. X: cannot open shared object file: No such file or directory.”

After this error message, the application gets terminated unexpectedly and you can not use it any more.

This situation occurs with the applications which are using shared libraries. This problem occurs if your computer has incompatible libraries to the applications and system have mismatched file versions of libraries.

Another cause of this problem could be the corruption to system files. The corruption could be the result of virus attack. Due to corruption, the application could not allow the required files and fails to start.

Regardless of the reason, this error message cause to the inaccessibility of your precious data stored on the hard drive and ultimately leads to data loss. To save your business critical data, it is extremely important to solve this problem as soon as possible.

To work around this problem, you can use the following two options:

1. If the problem is due to non compatible application or system libraries, update them.

2. If it does not work, the problem is due to system file corruption and it requires to reinstall the OS.

Reinstallation of OS is the solution of all the system related problems. But it also has a downside which can lead to data loss. Reinstallation requires hard drive formatting and formatting removes all the data stored on hard drive.

In these situations, you require for something which can perform data recovery Linux to recover your lost Linux data. The data recovery Linux is possible with the application of Linux recovery software.

Linux data recovery software are the perfect solution of Linux recovery. They can carry out data recovery Linux in all situations of data loss. These software are highly developed and do fast and effective Linux data recovery.

You can use this Linux data recovery software for all flavors of Linux to recover all sorts of lost files including documents, spreadsheets, library files, application data and many alike. User interface of this Linux recovery software is very cool looking and thus allows you to have trouble-free data recovery Linux.

Resolve Your Unexpected Inconsistency Error in Linux?

Linux is reliable OS due to the data security features it offers. But due cause like unexpected shutdown, a Linux file system might get corrupted and prevent you from accessing the data. Whenever you open a Linux system, fsck runs if finds any errors on the disk. However, if boot-time fsck cannot perform the desired repair task, it returns errors. To manage with such problems, you might need to reinstall the OS. You should use your backup to restore the lost data or scan the hard disk using Linux data recovery software.

For an instance, whenever you try to boot a Linux based system, it fails and gives the same error:

"/dev/sda5: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY

(i.e., without -a or -p options)"

You cannot see the data stored on your hard disk after this error message occurs.

Boot time 'Unexpected Inconsistency' generally occurs due to file system defects. Your file system might be corrupted. Possible causes for such defects are:

Improper system shutdown. For major reasons a Linux system performs file system buffering in its memory. The data written to the buffer memory is updated on the hard drive usually in every 30 seconds. The Linux file system can get corrupted if unexpected shutdown takes place while the write process is still running.

Faulty hardware: A damaged hard disk controller or disk itself can eventually corrupt a file system.

Given below are the steps that you need to undertake to solve the existing issue:

·Use Linux Rescue CD or installation disk to boot the system

·Execute the following command while making sure that the affected disk is not mounted:

e2fsck -f -c -y /dev/sda5

Ø-f option checks the filesystem even if it is appearing consistent

Ø-c options check the disk for bad sectors

Ø-y option answers 'yes' to all the questions while making repair

·If e2fsck fails, you need to format the corrupted disk and reinstall Linux. Restore lost data from backup thereafter.

While the non availability of valid backup, you require to use Linux recovery applications to search and restore the lost data. Linux data recovery tools employ high-end scanning algorithms and are competent to recover data in all set of conditions of logical crash.

Linux data recovery after file descriptor corruption

When you open your Linux system, during the boot process, you can receive errors related to file system corruption and the system may get hang. You may face the following error messages:

"Activating swap partitions: dup2: Bad file descriptor [FAILED]

Setting hostname Leshkow2: dup2: Bad file descriptor [FAILED]

/etc/rc.sysinit: /dev/null: Read-only file system

/etc/rc.sysinit: /dev/null: Read-only file system

Mounting USB file system: dup2: Bad file descriptor [FAILED]

Initializing USB controller (usb-ohci): dup2: Bad file descriptor [FAILED]"

And

"Grep: /proc/mounts: No such file or directory

Checking root file system

dup2: Bad file descriptor [FAILED]"

when these error messages occurs, you get the Linux shell prompt. At this situation, your system becomes totally unusable

These situation occurs due to corrupted or missing file descriptors. Due to the same, Linux can not locate and access the boot files and thus displays the above error messages.

The file descriptors are conceptual keys to view files. Usually the file descriptors are the indexes for entries in Linux kernel-resident data structure, which contains details of all the stored files. The file descriptors are stored in file descriptor table.

When the file descriptors not working properly, OS can not locate the stored files and thus the accessibility of these files become impossible. To overcome this condition, you have to perform Linux data recovery.

Data Recovery Linux is the solution to retrieve your inaccessible, missing or lost data. It is potential using third party applications, known as Linux Recovery software.

Such recovery software are easy-to-use tools, which perform methodical scan of affected hard drive and recover all data from it. These software incorporate powerful scanning algorithms to scan the hard drive and salvage all lost data.

The Linux recovery tools come equipped with different set of functions. To ensure optimum data recovery in Linux, it is essential to implement quality and powerful recovery software. These software are designed with features like largely automated functionality, to-the-point documentation, self-descriptive graphical screens and user friendly recovery options to achieve full-fledged recovery in all logical data loss cases.
