Some users think that no data would be lost in the event of power failure as long as they take measures at once. But, to be honest, it is not as simple as what you think. This article will focus on power failure and expose how it can harm your data.
Have you ever experienced sudden power failure when you’re dealing with your computer? For instance, you are editing a Word document in your Desktop PC. All of a sudden, power is off, and then the PC shuts down improperly. In this scenario, your first concern must be the Word document. Actually, power failure can pose great risks to your computer data, not only the unsaved files but also other kinds of data, such as system or software settings files, registry files and so on. Now, we will guide you to learn more about the dangers that power failure can cause to your data.
System & App Crash
When the power is shut down suddenly, it can result in abrupt system crash in your computer. The operating system and all the programs, which are running in the crash, may get damaged. Then, later when you power on your computer again, you will find some programs unable to run as normal. At worst, the computer is incapable of booting up as usual. In this scenario, you’ll lose access to your PC data.
Damage Computer Components
Besides, in the event of abrupt power failure, no matter outages or surges, the wires in your computer would be subject to electrical pressure, thereby leading them to heating up or being melted or burnt. Other components like chips may be damaged as well. Under this circumstance, you will be unable to read your PC data.
Lose Unsaved Files
Many users have experienced such a situation that they have no time to save the files they are editing when power fails abruptly. In this case, the files, no matter Word documents, Excel worksheets or others, may be gone forever. Of course, it’s still likely that next time when you start up your PC, you can recover them by any powerful software, such as to recover PST file via Outlook recovery tool.
Accelerate Computer & Drive Degradation
Perhaps you may find everything is still fine after power failure. To be specific, you still can boot up your PC in normal manner. All your computer data is intact as well. Yet, the case is not that simple. Actually, power failure will speed up the degradation of both your computer and internal hard drive. As we all know, hard drive is the place storing computer data. And it’ll surely die one day as soon as it reaches a certain age. At that time, the drive data will be lost.
