Data Recovery Process An Essential In Computing

Data recovery in computing language is known as the process of salvaging or retrieving the lost, inaccessible, damaged and formatted data from the secondary memory devices. This process is implemented when the data cannot be retrieved in a standard way.

Cleanroom data recoveryis often required due to the physical damaged and the logical damage, which damages the file system and is prevented from mounting by the operating system of the device.

The various reasons for data recovery are a failure of the operating system, hardware malfunction, and logical failure within the software, physical damage and accidental deletion of the data. The most primary step is to copy the data of the hard disk or create an image of the hard disk onto another storage device.

Data Recovery

Various Recovery phases.

In some cases, there is only a minute damage to the physical drive and by changing some physical parts data can be easily retrieved from the device. But for logical damage first, every byte of readable data is recovered using imaging techniques onto a reliable medium after that the disk is analyzed for logical damage for the reconstruction of the file manager.

  • Phase 1 (Hardware): The first step involves that the physical damage to the hardware should be repaired so that the hard disk can function enough to read the data from the hard disk. Then the data should be copied onto another memory disk to avoid data corruption.
  • Phase 2 (Software): Firstly the image of the drive is formed on to another drive such that there exists a copy of the data and then the operations of recovering the data can be employed. When logical error takes place mostly it is due to the corruption of the file manager which prevents mounting, in which the data is not made visible to the user by the operating system and to retrieve the data Live CD is used which is bootable computer software installation that directly runs through the ROM rather than from the hard disk drive. So it can run even when the hard drive is corrupted to retrieve the data. Software recovery is considered over the hardware recovery because it is easy and more efficient than hardware recovery which needs professionalism.

The hard disk drive is a delicate device and it should be handled with care and it is always preferred that the partitioning of the hard disk should be done such that directories, firmware and important files of the system are stored in another drive such that the recovery can be done easily.

Things to consider while you opt for computer repair

Computer Repair

Many times, your computer switches off without a warning, exactly when you haven’t saved your work. The worst times are the power failures which don’t turn up for hours, if you are an Indian, you know how it works.

Computer repair is a business of its own. Right from installation to frequent problems set right, the computer repair guy seems to save the day all the time.

  • What actually goes into computer repair?

Right from the CPU overheating due to insufficient space and the system running corrupt, there’s nothing that cannot be repaired back to perfection when it comes to computers. Yes, the cost is something you got to bear, given that the damage is done!

Computer Repair

  • Do there exist online platforms for computer repair?

Well, yeah. Everyone appreciates the curiosity to fix things on your own, if not to save the costs. There are a couple of really good websites which help you identify and sort out almost all problems but are mainly software oriented. One such is ComputerAssitant.com. They have organized all possible issues you could come across your PC, and also provide a step by step help out guide.

  • What if, you are one among the ‘Supermans’ in this domain?

The best would be to seek out to the nearest digital showroom and get a good job for your passion and interests. If not full time, these online platforms are also hiring technicians who are ringed upon necessity, along with tasks of addressing customer issues online. A worthy domain to make good money.

  • How to take care of the data security while giving for repair?

In unavoidable scenarios, especially when it’s the hardware of the system that needs a check, make sure you transfer all your important data to an external hard disk, system reset the computer before handing it out to the repair person. This is highly recommended for confidential projects or data files.

  • Recycling old computers

Whether you recycle for money or karma, make sure you don’t dispose of them straight down your daily waste. E-waste demand to be treated differently. There ae many organizations like E-Cycle, Gazelle, NextWorth and even welfare organizations like the National Cristina Foundation, which take these old used electronics to give them a second life, maybe!

The next time you have any computer repair issue, now you know how to handle it.

10 Technology Trends that Can Change the World

The rate of technological change today is directly proportional to the computational power in use. As much as disruptive technology is unpredictable, it is still quite possible to have a hint of what the future holds in terms of technology. At Cisco Live, chief technologist and futurist for the Cisco IBSG, Dave Evans, stated some of the technological trends that could change the world. Outlined below are some of the trends that were stated.

1. New Cloud Power

It is predicted that within a short time, a third of all data will pass through, or live in the cloud. When connected to a device, it will be possible to give real-time information such as what a person is doing at the specific moment. For example, one person can tell that the other person is driving, meaning that it is not the appropriate time for them to video call the other party.

2. Advanced Additive Manufacturing

3D printing involves the process of integrating materials to create objects from the 3D model data. With this advanced technology, it will be possible for human beings to manufacture physical items such as food and clothes, among others.

3. Zettaflood

In 2011, there was the creation of 1.2 zettabytes. One zettabyte is equivalent to 1024 exabytes. Therefore, the use of video internet data is increasing immensely over the years. However, this zettaflood will require advanced networks to facilitate effective functioning.

4. Normality of the Use of Nanobots in Medical Centers

The introduction of devices such as nanobots in hospitals can transform the medical sector as they will facilitate the treatment of many conditions, if not all.

5. Use of Advanced Interplanetary Network

Technologists predict that the internet speed present today could increase by 3 million times in the next ten years. With the use of an Interplanetary network, this will be possible as it allows the flow of data over wide distances without disturbance.

6. The Internet of Things

Today, the number of things connected to the Internet is more than the number connected to people. Therefore, Cisco predicts that in less than five years, the number of things connected to the Internet will amount to around 50 billion in total.

Having such a large number of things connected to the Internet means that it will be easier to carry out different activities.

7. Virtual Humans

Dave Evans predicts that in 2032, human beings will be mentally inferior to robots. After three years, the robots could completely take over the workforce. Thus, this will result in huge advancements in most sectors such as communication and health.

8. Proper Investment in Solar Energy

Researchers from Oregon State University discovered how to print solar cells through the use of an inkjet printer. The practice is stated to be relatively affordable, thus applicable to sustain the increasing population of human beings on earth.

9. Creation of Borg

It is predicted that there could be the creation of a powerful species that will be partly man and part machine. This will be a huge turning point for human beings.

10. A Smaller World

A smaller world will facilitate faster dissemination of information. In turn, events will be able to go from near time to real time, thus promoting the immediate influence of different cultures.
