Data loss is one of the major problems among all the computer users including individual PC users and the professional PC users who are working in business environment. You may lose your data due to many reasons, I will discuss about this part later. In this tech world, day to day new types of electronic data are created by many technology geeks and these data volumes have become much more than the requirement over a span of few years. Classical or we can say old data management tools and techniques failed to keep these large amounts of information/data. Therefore to prevent this critical situation of protecting data and overcome data loss, now all the large, medium and small size organizations use to secure their prior data/information in data center hard drives, servers and also use to create and maintain backup system in regular interval. No matter where the organizations save their data, still the security of data in many companies is under question mark.
All over the world, every organizations and individual computer users are putting their maximum effort to secure their data, but still data loss occurs due to many reasons. In the past few years, data loss has become one of the major reasons for business loss in many organizations. Most of the companies don't plan about security of their data/information and having unstructured way of maintaining their data are the main reasons behind most of the organization's shut down in past few years.
What are the Prime Reasons for Data Loss
There are various types of reasons behind the data loss in a business environment and in individual user such as natural disasters (flood or earthquake), accidental delete, system failure and many more. So let's have a small look on, what are the possible reasons for data loss in a computer.
Hardware failure
Software corruption
Human errors
Computer viruses
Natural disaster
The following pie chart gives a clear idea about possible data loss reasons in a computer with their percentage.
Hardware Failure
This is one of the major reasons for data loss since long time. Some of the hardware failure may create a path for data loss in a computer. The thing in this cause is you are not able to detect such hardware failures in advance. For example high failure rates are linked with the entire storage media device and when it fails, you might lose all the data without any alert. Only the possible way to prevent data loss due to the hardware failure is, maintain a proper backup system for the data.
Software Corruption
Software corruption is listed next to hardware failure as a reason for data loss in a computer. Software corruption is a type of logical failure which leads to complete destruction of the data from the storage device. Any errors in the system or defects in the system can be the reason for software corruption.
Human Errors
Human error is another reason behind data loss in a computer. If a person lose data due to the human error, he is responsible for losing vital data assets. Keep in mind; humans have a mind setup like irresponsible and careless about the policies of following procedures, so this can result in data loss. This mind setup is considered as the most possible reason for data loss due to the human error. But still there are huge list of human error which can be considered as reasons for losing data such as careless when rebooting the system, accidental deletion of data, no proper virus protection and many more.
Computer Viruses
This is a well known reason for data loss in a computer as well as it can be listed under human error too. Viruses can damage not only your data from the hard disk, it can malfunction the operating system by crashing the boot sector of the hard disk too. The major reason of losing data due to the virus attack is, not having a firewall in the system or not installing or updating the antivirus guard. So the computer user must consider about virus protection of the PC to secure their data.
Natural Disaster
Losing the data in a computer due the natural disaster like flood or earthquake is counted very less in past few years. But still it took 3 percentages in the pie chart of 'possible data loss reasons'.
Data Recovery Planning and Maintenance
Keep in mind, there is no any shortcuts available to recover data if you lose it. So now all the small to large size companies have realized the importance of data recovery planning and maintaining the proper data recovery system within their organization. A recent report says most of the small to medium size company spend more than 6 hours to plan, create and maintain the data recovery process within their business plans. Whatever, if a company maintains a proper data recovery strategy, then they can avoid such a critical situation.
Data recovery plan and maintenance is a must for all the organizations, which can put back your business into the right track. If you are thinking to plan and create data recovery strategies for your business, you can find many specialized group of companies which gives you professional data recovery techniques and tools. Professional data recovery software is able to recover your formatted, lost, crashed and deleted data without causing loss.
Technology Behind Data Recovery Tool
You can find hundreds of free and paid data recovery tools in the internet. When you try to recover deleted data with those free/paid data recovery tools, you get positive or negative results. Sometimes you might recover your deleted data successfully and sometime you don't. I will discuss the possible reasons for this situation in next topic. Data recovery tools are designed by companies on considering various facts such as storage architecture, cost of data management, growth in structured data and few more facts.
Now let's have a small and clear look on what is the concept behind data recovery tool and how is the data recovery tool programmed. When you lose files from the hard disk due to accidental deletion or any other possible reasons, what happens to that lost files and where it goes? I believe such questions would have arisen in your mind. Here's the answer!
When a file gets deleted by the user in a computer, the deleted file still remains in the memory or some comparative areas until it gets deleted permanently by the current operating system of the computer. After the continuous innovation by the data recovery tool developing programmers, they developed the data recovery tools with the proprietary, recovery techniques and some recovery algorithms, which can able to scan the storage device for recently deleted files. These technologies and algorithms are developed on data recovery tools, after many years of research. So now you're thinking that if you have a powerful data recovery tool, you can recover any previous deleted files. Well it's wrong. I request you to highly consider on the following message for a successful data recovery.
Stop using the affected hard drive and avoid copying new files to the hard drive, until the data recovery tool recovers your lost data successfully.
Rules to Consider before going for Data Recovery
I request you to stop using the affected hard disk drive to prevent overwriting of deleted files. When you delete or lose any file or folder from the hard disk, it goes nowhere. When you give delete command for a file or folder, the certain file's index gets remove from the hard disk. So a question might come to your mind what is index? Well, the index is the entry of each and every files of the computer which is in the 'Index Table' of the operating system. When you delete a file from the hard disk, the file does not remain in the index entry in the index table of the operating system. So the operating system is unable to find the file anymore and it's ready to replace the space with any of a new file. When you keep on using the affected hard disk drive to copy new files, there is a huge chance created for overwriting new data over the lost/deleted files in the affected hard drive. Even most of the professional data recovery tools cannot recover the deleted data, if it gets overwritten by a new file. So keep in mind, you must NOT use the affected hard drive, if you want to recover the deleted files successfully.
What is the First Step You Have to Follow After the Data Loss in a Hard Disk
Data loss may occur due to many reasons such as hardware failure, software corruption, human errors and much more. If you are having a good data recovery tool, it doesn't mean you can get back all the lost data. You must follow the right steps to recover the deleted files before scanning the hard drive with data recovery tools.
Here I have listed few important points to consider, to create a good chance to get back the deleted/ lost data successfully.
If you lose data due to hardware failure and if the failed drive is the boot drive of your computer system, then DO NOT try to reboot the system from the particular drive. If you boot the system with the particular drive, there is a huge space for data damage.
If you lose data due to any of physical failure, then DO NOT try to recover the deleted files with any of data recovery tool. If you want to recover the deleted or lost data from the physical failure hard disk, better you contact a professional data recovery company for recovery process.
If you lose data due to system corruption or any of software corruption, then you can go with any of powerful data recovery software to recover the deleted files.
If your hard disk drive consists any of bad sectors, then DO NOT try to recover the deleted files with a data recovery tool. If you use a data recovery tool to get back the deleted files on a hard drive which includes bad sectors, it might damage the sectors of the hard disk and decrease the chances of successful data recovery.
Final Words
Now I believe you have got the complete idea about data recovery planning, maintenance, how a data recovery tool is programmed, how a data recovery tool works on the mechanism, what's the technology behind data recovery tool, what are rules to consider for successful data recovery and many more.
Make sure you know about the right process thoroughly before doing it. This article has covered all the major topics of data recovery. So now you can try a perfect data recovery process with a professional data recovery tool, in case if you lose any data from your hard disk or any other media storage devices.
