What Is Data Loss | Definition, Causes, Prevention Methods, and Data Recovery

What Is Data Loss

When using data storage devices, you may encounter data loss. So, what are data loss means? Suppose your information is destroyed by failure, transmission, or processing; the information system will enter the error condition: data loss. And data loss can also occur when the physical medium that stores the data is lost.

Data Loss Types

Data loss types can be divided into several parts, and the main data loss types include data loss caused by intentional action, unintentional action, failure, disaster, crime, etc.

🧑‍🔧Intentional Action	Intentional deletion of files or programs
😣Unintentional Action	Accidental deletion of files or programs Misplacement of physical storage media
⚠️Failure	Failure of power, hardware, software Software crashes, freezes, bugs, or poor usability Data corruption
🔥Disaster	Nature disaster
🧑‍💻Crime	Theft, hacking, sabotage

And it has been found that hardware failure and human error account for about three-quarters of data loss types.

Common Causes of Data Loss

Data loss can be a serious issue for individuals and businesses, which means losing time and energy to retrieve essential data. Numerous factors can cause data loss. According to research, hard drive crashes account for the highest percentage.

Here are the nine common causes of data loss:

1. Hard Drive Damage

Most data losses are caused by hardware malfunctions. Hard drives are fragile, and they could be damaged as your computer is overheating due to overuse. And here are some signs which indicate your hard drive may be damaged:

• Your hard drive frequently crashes.
• Your computer is always overheating.
• The speed of the process becomes slower.
• Your computer freezes frequently.
• Your computer makes abnormal noises while working.

2. Human Error

Human error could play an important role in many other causes of data loss, such as hard drive damage, software corruption, and hard drive formatting. Human error can result in the unintentional deletion and overwriting of important files without realizing it.

3. Software Corruption

While software corruption can sometimes result from other factors of daily loss, such as power outages or other uncontrollable factors, it is essential to implement procedures for adequately shutting down software after every use.

Unexpected or improper software shutdowns may cause severe issues for the data on your computer. Improper shutdowns can corrupt your data or delete your progress, wasting time and losing valuable data.

4. Hard Drive Formatting

Intentional or unintentional formatting of your hard drive can cause you to lose data. And if you write new data on the formatted partition on your hard drive, the data may be lost forever and can't be restored anymore. If you only format your hard drive without writing new data, you can use data recovery software to restore your lost data.

5. Viruses and Malware

Viruses can delete and steal essential data, destroy functionality, and bring operations to crawl. Viruses could attack your computer from an email link or a click on a corrupted link, which allows viruses or malware to enter your computer system.

6. Power Outages

Power outages can shut down the processes you are working on without warning, resulting in the loss of unsaved files. And it can cause files to be corrupted due to improper shutdown of the process.

In addition, programs could be rendered non-functional by power outages. If your computer shuts down due to a power outage while it's writing the hard drive system, it's possible that your computer will not be bootable.

7. Theft of Physical Storage Medium

Physical storage medium theft is a potential risk when people use small office devices, such as laptops and smartphones, to work in public places. In addition to losing data, physical storage medium theft also poses the risk of data leakage. Studies show that stolen or lost devices accounted for more than 40% of all data breaches from 2005 to 2015.

8. Liquid Damage

Note that keeping liquids away from your computers, for that liquid damage can cause short circuits, making it difficult to recover data on your computer.

Even sometimes, the computer seems to work fine after spilling coffee or water on it, but internal damage can influence the computer and make it short-circuit later. Especially acidic drinks, such as coffee, can corrode the inside of the computer.

9. Disasters

Natural disasters, including earthquakes, tornadoes, and fires, can occur when you are most unexpected and have a devastating impact on your vital data. They can destroy your computer and your data and even destroy your work completely.

To minimize the impact of the disaster and ensure your work process can continue, you can back up your essential data once a week and store it in a secure location.

How to Prevent Data Loss

In both real life and work, we want to avoid facing data loss, which consumes energy, time, and money.

In addition to creating backups of your essential data, here are some effective methods to prevent data loss:

• Partition your hard drive: it means you can create separate data zones on your hard drive so that you can recover the data if the data partition crashes.
• Perform defragmentation of your disk: it helps to arrange files to speed up your computer's processing time and lower the risk of data loss.
• Install anti-virus software on your PC: it helps to prevent viruses or malware from infecting your computer. Note that you should keep the anti-virus software updated to ensure its function.
• Encrypt your data: whether encrypting your data storage device or encrypting your data can help you reduce the risk of data loss, especially the possibility of data leakage.
• Keep your computer dry: moisture in the computer can cause the crash of the hard drive and overheating of the computer, so keep your computer dry.

Data Loss Prevention in Company

Data Loss Prevention, known as DLP, is a set of processes designed to avoid data loss and unauthorized access to sensitive data. Many companies and organizations use DLP to:

• Protect personally identifiable information which complies with relevant regulations.
• Protect intellectual property.
• Secure data in the environment workers bring their own devices.
• Secure data on the remote cloud system.

Data Recovery on Windows 10/11 and macOS

Have you ever experienced data loss in your life and work? If so, then you may need to learn about data recovery. Data recovery is restoring lost, corrupted, accidentally deleted, or otherwise inaccessible data to its server, computer, mobile device, or storage device.

If you deleted or lost essential data and need to know how to recover it. Here are three methods to help you restore your data:

Data Recovery Using Software

The easiest and fastest way to retrieve lost or deleted data is to use data recovery software like EaseUS Data Recovery Wizard. This data recovery tool can work on Windows OS and macOS.

And the operation of EaseUS data recovery software is easy:

Step 1. Select the partition your deleted/lost data stored before.

Step 2. Click "Scan" to view all the deleted/lost data.

Step 3. Choose the data you want to restore and click "Recover".

Data Recovery from Specialize Services

You can ask data recovery services for help if you can't install data recovery software on your computer or you can't recover the deleted/lost data yourself. Experts who have been experts in data recovery for over 18 years from EaseUS data recovery service can help you recover different file types under various situations, including recovering permanently deleted files from an external hard drive, RAW partition recovery, etc.

For example, you can use some built-in backup tools like Windows Backup or Time Machine to make backups. Or you can use backup software like OneDrive, Clonezilla, Cobian Backup, etc.

Conclusion

Suppose your information is destroyed by failure, transmission, or processing. In that case, the information system will enter the error condition called data loss, which can also occur when the physical medium that stores the data is lost.

The main types of data loss are hardware failure and human error. And many factors can cause your computer to lose its data. In this case, you can install EaseUS Data Recovery Wizard to recover essential data, the easiest and fastest way to restore your data.
