Author: The booting process of the Linux operating system can halt due to various software (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.
To completely and systematically access of data, you need to restore it from the latest backup. But in case of no backup availability, you should use effective Linux Data Recovery software for software corruption issues. However, if the corruption has been caused due to some hardware issues and there is no backup available, Linux Data Recovery services come to rescue.
Consider a practical scenario, where you receive the below error message when you attempt to boot the Linux operating system:
“The System Log Says, end_request: I/O error …”
After the 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.
Cause:
The key reason for the occurrence of the above error message is the hard drive error. Few causes that might 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
Resolution:
To resolve the above problem and access the data, you need the assistance 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.
Stellar Information Systems Limited, a world wide trusted data recovery organization, provides complete Linux Data Recovery in all physical loss scenarios. The rich experienced data recovery experts firstly analyze the percentage of data that can be recovered from the physically damaged hard drive. After examining, these experts perform recovery of data in the sterile environment of Class 100 Clean room facility.

Just what is a motherboard? What does “Advanced TCA” mean? What do various motherboards do for your computer? Here are some of the answers to those questions to help you learn more about computers in general and make the best choices when you buy your next one. At its simplest, a motherboard is the central printed circuit board used in many different complex electronic systems, of which personal computers are only one. Motherboards may be called the system board or mainboard, as well. In Apple computers, this part is referred to as the logic board.
Most motherboards today are made for IBM-compatible computers, after all, they make up 90% of computer sales around the world. Motherboards provide the electrical connections that other components use to communicate with one another, just like a backplane. However, they also host many subsystems and devices, as well as the computer’s CPU. The average desktop computer has the main memory, processor, graphics and sound cards, and other important components placed on the motherboard. Some components, like peripheral devices and external storage, as well as some sound and graphics cards, are plugged into the motherboard, rather than being integrated into it.
A vital component of motherboards is the chipset used to support the microprocessor, which provides the interfaces that support the buses, CPU, and external components. This chipset helps determine what the motherboard is capable of doing. A modern motherboard will include a minimum of a slot or socket to install the processor into, slots for memory installation, a chipset that acts as an interface between the main memory, front side bus, and peripheral buses, a clock generator, nonvolatile memory chips, firmware, expansion slots and power connectors. However, many motherboards include a lot more than this, since there are many more demands being made on them all the time.
All worthwhile motherboards include connectors for ordinary input devices, like USB and PS/2 connectors, parallel connectors, or FireWire connectors. While early computers used only minimal peripheral support, modern computers use a lot of plug in devices, resulting in more connectors and different types of connectors. Heatsinks and fan mounting points are also included, since modern computers produce a quantity of heat that is detrimental to their functioning. It’s important to keep electronics cool at all times, so that they’ll function at their best capacity.
There are a number of specifications for motherboards depending on what they’re being used for. The ATX format is the most common for computers, with smaller versions of the standard also being produced. Other devices may use other standards, including Advanced TCA or ATCA, which is the new standard for telecom applications. It combines the features offered by proprietary architectures and the Compact PCI standard with high packing density, as well as serviceability, availability and reliability. Phones, PDAs and other electronic devices may have their own unique motherboards.
If you’re in the market for powerful Advanced TCA motherboards, make sure you buy from a respected Advanced TCA manufacturer.

After a successful run of the computer system, the next day, when the user sits to work further, the hard drive is found to be crashed. Isn’t the story familiar to hear? Perhaps for some of you, it is. The hard drive failed and there is no operational ability that means no data access and hard disk recovery can make it possible. But, do you know the reason, why this happened? Let’s find out.
About Hard Drive
Hard drive is the creation through mechanical minds which has set of spinning platters that have layers of metal oxide material coated over them to retain data, a shaft mounting those platters, a motor to make the shaft moving, a bunch of read/write heads, actuator arms, electric control board and more. Platters spin at high speed in certain thousands of revolutions per minute, hold magnetic charges which are sensed by the heads so as to have data access privileges.
The read/write heads (each platter surface except the extremes has a head), which are attached to the actuator arm float at about 1-2 micro-inches height from platter surface on a cushion of air. Data flow happens through these heads via electrical connections. Now, with this ideal structure, any distraction implies the data loss is there and hard disk recovery is required.
About Data Loss Trend
With the increasing capacity of hard drives, hard disk recovery is setting more into business and the main reason behind is that data is being stored comparatively in smaller spaces. As compared to the last years, the storage capacity has multiplied itself and as a result has amplified the impact and chances of hard drive failure. Mechanical precision is getting smaller by the day as data is now stored on denser areas.
About Head Crash
A mere push, a contaminant entrance, power surge or any of the apparently small reason can make the head crash and the severest case says that due to scratched platters, data get permanently ruined. The head has come closer to the platter surface, at about 1-2 micro-inches. Now, the standard dust particle size is about 4-8 micro-inches and that of human hair is 10 micro-inches. So you can judge it out, how reckless it could be to have hard disk recovery attempts including opening it in the normal environment.
About Hard Disk Recovery Considerations
Hard disk recovery understands all the points such as what are the internal requirements, what is the suitable way to tackle, which is the precise procedure to have data recovery, the apt surroundings and more. The technicians have now generated tools and techniques which go accordingly with the latest developments in the hard drives.
Hard disk recovery is no more an issue, but with the insufficient ones, still it is. Clean Rooms have been set in order to offer the suitable dust-free surroundings.

Stellar Information Systems Limited is the place where you can sort out all your hard disk recovery queries. The Class 100 Clean Rooms, expertise of technicians, kno-about of all type of hard drive internals, high-tech bunch of tools and techniques, all combine to offer you the best help in hard disk recovery.
