What Is Data Corruption? Symptoms & Causes of Data Corruption

Data corruption refers to errors in computer data during writing, reading, transmission, storage, or processing, which can cause unintended changes to the original data. When data corruption occurs, if a system or application attempts to access the file, including the data, it will suffer severe consequences, ranging from minor data loss to a serious system crash.

What your computer or devices will happen when data corruption occurs? There are some common symptoms of data corruption:

  • The disk hangs or performs slowly.
  • File error comes with "invalid file format".
  • Files and folders are displaced or lost.
  • The computer regularly crashes or hangs for no apparent reason.
  • Disk action seems very busy, even though not many things are going on.

Data corruption will significantly damage our data on computers, so it is vital to know the causes of data corruption on Windows computers. Here are some reasons why your computer data get corrupt:

  • Malware attacks and computer viruses can corrupt your data.
  • A failing hard drive can lead to data corruption.
  • Data corruption may result from improperly saving files.
  • The data can also get corrupt when you improperly unplug storage devices from the computer.
  • Disk sectors sometimes go wrong, thus corrupting the files and folders.

3 Strategies to Prevent Data Corruption in Windows Computers

Data corruption has become one of the most common causes of permanent data loss. Therefore, it's essential to know how to prevent it. Here are three ways to help us avoid data corruption on our computers.

  1. Correctly Remove External Hard Drives from your Computer
  2. Use Antivirus Software on Windows Computer and Always Update It
  3. Keep an Eye on Hard Drive's Health

Correctly Remove External Hard Drives from your Computer

When using an external storage device, you should not just unplug it from the computer because you never know whether or not a background program is accessing a file. And doing this may lead to file corruption. In light of that, it is a good idea to eject the external drive before you unplug it from your computer. This will help prevent data loss from your external hard drive since applications will no longer use the data when unplugging.

Use Antivirus Software on Windows Computer and Always Update It

There is no denying the fact that viruses and malware are constantly developing and have become an important factor in data corruption. They can change your file from its original form to another form that is different from what the app that uses or your computer can read. This is why using antivirus software on your computer is also crucial. Firstly, you require a reputable security suite, including the best antivirus software, firewall, and other multi-tiered protections. Secondly, if you use emails, you should be aware of email-borne viruses. Doing so can save your data from getting infected by viruses or malware.

Keep an Eye on Hard Drive's Health

Although it's always a good idea to regularly check your hard disk health for Errors & Bad Sectors, it is equally essential to monitor the hard disk regularly if you do not want to be caught unaware by a hard disk failure for no apparent reason. One approach is to use S.M.A.R.T (Self-Monitoring, Analysis, and Reporting Technology) to monitor the hard drive's health and send out signals if it fails. The other one is to apply the scan disk tool if you are using Windows operating system.
